ABSTRACT
This guide covers a cleaning and descaling procedure useful to producers, users, and fabricators of titanium and titanium alloys for the removal of ordinary shop soils, oxides, and scales resulting from heat treatment operations and foreign substances present as surface contaminants. It is recommended that the materials shall be subjected to soil removal prior to heat treatment or application of acid treatment. Mechanical descaling methods such as sandblasting, shot blasting, and vapor blasting may be used to remove hot work scales and lubricants from titanium surfaces. Recommended post treatment of shot or abrasive blasted titanium surfaces may include acid pickling to ensure complete removal of surface contaminants. For chemically milled materials, salt bath conditioning may be required to remove the oxygen-contaminated layer. Acid etching treatment may be required following mechanical abrading or chemical conditioning of materials to completely clean the surface.
SCOPE
1.1 This guide covers a cleaning and descaling procedure useful to producers, users, and fabricators of titanium and titanium alloys for the removal of ordinary shop soils, oxides, and scales resulting from heat treatment operations and foreign substances present as surface contaminants.  
1.2 It is not intended that these procedures be mandatory for removal of any of the indicated soils but rather serve as a guide when titanium and titanium alloys are being processed in the wrought, cast, or fabricated form.  
1.3 It is the intent that these soils be removed prior to chemical milling, joining, plating, fabrication, and in any situation where foreign substances interfere with the corrosion resistance, stability, and quality of the finished product.  
1.4 Acid etching may be required following cleaning when the surface has an oxygen-contaminated layer or alpha case present.  
1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

ABSTRACT
This specification covers seamless and welded titanium and titanium alloy tubing on which the external or internal surface, or both, has been modified by a cold forming process to produce an integral enhanced surface for improved heat transfer. The tubes are used in surface condensers, evaporators, heat exchangers and similar heat transfer apparatus in unfinned end diameters of a specific size. Tubes shall be furnished with unenhanced ends in the annealed condition and shall be suitable for rolling-in operations. Each tube shall be subject to a nondestructive eddy current test, and either a pneumatic or hydrostatic test.
SCOPE
1.1 This specification covers seamless and welded titanium and titanium alloy tubing on which at least part of the external or internal surface has been enhanced by cold forming for improved heat transfer. The tubes are used in surface condensers, evaporators, heat exchangers, coils, and similar heat transfer apparatus in diameters up to and including 1 in. [25.4 mm]. The base tube wall thickness is typically at least 0.049 in. [1.245 mm] average, but lighter gauge may be negotiated with the manufacturer.  
1.2 Tubing purchased to this specification will typically be inserted through close-fitting holes in tubesheets, baffles, or support plates spaced along the tube length such as defined in the Tubular Exchanger Manufacturer’s Association (TEMA) Standard.2 The tube ends will also be expanded, and may then be welded.

ABSTRACT
This specification covers virgin titanium metal melting stock. This virgin metal is commonly designated as sponge titanium because it is most commonly porous and spongelike in texture, although metal produced electrolytically is granular and is essentially nonporous. Sponge titanium is usually prepared by reduction of titanium tetrachloride and gets its spongelike character from the processes involved in production. This spongy characteristic, however, is not considered essential and may be expected to vary greatly with manufacturing methods. For example, virgin titanium produced electrolytically is crystalline or granular in character and is essentially nonporous. The metal is usually supplied in lump or granular form. The virgin titanium shall be free of scrap, intentionally added contaminants and shall be in uniform, well-mixed blends. The titanium metal shall conform to the chemical composition and Brinell hardness requirements prescribed.
SCOPE
1.1 This specification covers the purchase of virgin titanium sponge metal. This virgin metal is commonly designated as titanium sponge because it is most commonly porous and sponge-like in texture, although metal produced electrolytically is granular and is essentially nonporous.  
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

ABSTRACT
This specification covers annealed titanium and titanium alloy strip, sheet, and plate. The grades of titanium and titanium alloy metal covered by this specification shall have the chemical composition requirements of: nitrogen, carbon, hydrogen, iron, oxygen, aluminum, vanadium, tin, ruthenium, palladium, cobalt, molybdenum, chromium, nickel, niobium, zirconium, silicon, and titanium. For sheet and strip, the bend test specimen shall stand being bent cold through without fracture in the outside of the bent portion. Product analysis tolerances cover variations between laboratories in the measurement of chemical content of the specimen. In cutting samples for analysis, the operation should be carried out insofar as possible in a dust-free atmosphere because utmost care must be used in sampling titanium for chemical analysis due to its great affinity for elements such as oxygen, nitrogen, and hydrogen. The chemical analysis shall be conducted by the standard techniques normally utilized by the manufacturer and purchaser.

ABSTRACT
This guide covers a cleaning and descaling procedure useful to producers, users, and fabricators of titanium and titanium alloys for the removal of ordinary shop soils, oxides, and scales resulting from heat treatment operations and foreign substances present as surface contaminants. It is recommended that the materials shall be subjected to soil removal prior to heat treatment or application of acid treatment. Mechanical descaling methods such as sandblasting, shot blasting, and vapor blasting may be used to remove hot work scales and lubricants from titanium surfaces. Recommended post treatment of shot or abrasive blasted titanium surfaces may include acid pickling to ensure complete removal of surface contaminants. For chemically milled materials, salt bath conditioning may be required to remove the oxygen-contaminated layer. Acid etching treatment may be required following mechanical abrading or chemical conditioning of materials to completely clean the surface.
SCOPE
1.1 This guide covers a cleaning and descaling procedure useful to producers, users, and fabricators of titanium and titanium alloys for the removal of ordinary shop soils, oxides, and scales resulting from heat treatment operations and foreign substances present as surface contaminants.  
1.2 It is not intended that these procedures be mandatory for removal of any of the indicated soils but rather serve as a guide when titanium and titanium alloys are being processed in the wrought, cast, or fabricated form.  
1.3 It is the intent that these soils be removed prior to chemical milling, joining, plating, fabrication, and in any situation where foreign substances interfere with the corrosion resistance, stability, and quality of the finished product.  
1.4 Acid etching may be required following cleaning when the surface has an oxygen-contaminated layer or alpha case present.  
1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.6 This standard does not purport to address the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

This specification covers plate consisting of a base metal to which is bonded, integrally and continuously, on one or both sides a layer of one of the following: titanium, zirconium, tantalum, niobium, and their alloys. The material generally is intended for pressure vessel use. The cladding metal shall be bonded to the base metal by any cladding operation that will produce a clad product which will conform to the requirements of this specification. When the cladding operation does not affect the chemical composition of the cladding or base metal, or both, the chemical analysis, in accordance with cladding, or base metal specifications or both, may be performed prior to the cladding operation. All heat treatments shall be performed as needed in the cladding operation unless otherwise specified or agreed between the purchaser and the manufacturer. Mechanical testing of the base metal, in accordance with the base metal specification, may be performed prior to the cladding operation. The tensile properties shall be determined by a tension test on the base metal only in accordance with the testing requirements of the base metal specification. The specimen orientation, location with respect to thickness, and number of tests and retests shall be in accordance with the requirements of the base metal specification when tension, bend, and impact tests shall be performed. The product surfaces shall be free of excess imperfections and extraneous materials as determined by visual examination.

ABSTRACT
This specification covers virgin titanium metal melting stock. This virgin metal is commonly designated as sponge titanium because it is most commonly porous and spongelike in texture, although metal produced electrolytically is granular and is essentially nonporous. Sponge titanium is usually prepared by reduction of titanium tetrachloride and gets its spongelike character from the processes involved in production. This spongy characteristic, however, is not considered essential and may be expected to vary greatly with manufacturing methods. For example, virgin titanium produced electrolytically is crystalline or granular in character and is essentially nonporous. The metal is usually supplied in lump or granular form. The virgin titanium shall be free of scrap, intentionally added contaminants and shall be in uniform, well-mixed blends. The titanium metal shall conform to the chemical composition and Brinell hardness requirements prescribed.
