(Specification)Standard Specification for Titanium and Titanium Alloy Castings
Standard Specification for Titanium and Titanium Alloy Castings
ABSTRACT
This specification covers the standard requirements for titanium and titanium alloy castings intended for general corrosion resistant and industrial applications. Materials for this specification shall be melted by conventional processes used for reactive metals such as consumable electrode and induction-slag, plasma arc, induction-skull, and electron beam melting processes. The materials shall undergo chemical, pour, and product analysis to determine the chemical composition which shall conform to the requirements for nitrogen, carbon, hydrogen, iron, oxygen, aluminum, vanadium, tin, ruthenium, palladium, cobalt, molybdenum, chromium, nickel, niobium, zirconium, silicon, and titanium. All castings shall be supplied in the as-cast condition except when post-weld heat treatment is required wherein it shall consist of a stress relief performed at certain temperatures. The surface of the castings shall be free of adhering mold material, scale, cracks, and hot tears as determined by visual inspection.
SCOPE
1.1 This specification covers titanium and titanium alloy castings intended for general corrosion resistant and industrial applications.
1.2 This specification is intended for use of purchasers and/or producers of reactive metal castings for defining the requirements and assuring the properties of castings for unique corrosion-resistant applications, that is, not for commodity items which must meet all potential purchasers' requirements.
1.2.1 Users are advised to use the specification as a basis for obtaining castings which will meet minimum acceptance requirements established and revised by consensus of the members of the committee.
1.2.2 User requirements considered more stringent may be met by the addition to the purchase order of one or more supplementary requirements, which may include, but are not limited to, those listed in Sections S1 through S8.
1.3 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.
