ASTM B265-20a

Standard Specification for Titanium and Titanium Alloy Strip, Sheet, and Plate

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.

TABLE 3 Permissible Variations in Weight of Cold Rolled
Titanium Sheet
The actual weight of any one item of an ordered thickness and size in any
finish is limited in overweight by the following tolerance:
Any item of five sheets or less, or any item estimated to weigh 200 lb (91
kg) or less, may actually weigh as much as 10 % over the estimated
weight.
Any item of more than five sheets and estimated to weigh more than 200 lb
may actually weigh as much as 7 ⁄2 % over the estimated weight.
There is no under tolerance in weight for titanium sheets, under tolerance being
restricted by the permissible thickness variations.
Only random (or mill size) sheets may be ordered on a square foot basis, and
the number of square feet shipped may exceed the number ordered by as
much as 5 %.
4.1.7 Additional required reports (Section 15), and
4.1.8 Disposition of rejected material (Section 14).
5. Chemical Composition
5.1 The grades of titanium and titanium alloy metal covered by this specification shall conform to the chemical composition
requirements prescribed in Table 8.
5.1.1 The elements listed in Table 8 are intentional alloy additions or elements which are inherent to the manufacture of titanium
sponge, ingot or mill product.
5.1.1.1 Elements other than those listed in Table 8 are deemed to be capable of occurring in the grades listed in Table 8 by and
only by way of unregulated or unanalyzed scrap additions to the ingot melt. Therefore, product analysis for elements not listed in
Table 8 shall not be required unless specified and shall be considered to be in excess of the intent of this specification.
5.1.2 Elements intentionally added to the melt must be identified, analyzed, and reported in the chemical analysis.
5.2 When agreed upon by producer and purchaser and requested by the purchaser in his written purchase order, chemical
analysis shall be completed for specific residual elements not listed in this specification.
5.3 Product Analysis—Product analysis tolerances do not broaden the specified heat analysis requirements but cover variations
between laboratories in the measurement of chemical content. The manufacturer shall not ship material that is outside the limits
specified in Table 8 for the applicable grade. Product analysis limits shall be as specified in Table 9.

TABLE 5 Permissible Variations in Weight of Hot Rolled Titanium
Sheet
The actual weight of any one item or an order’s thickness and size in any finish
is limited in overweight by as much as 20 %.
5.4 At least two samples for chemical analysis shall be tested to determine chemical composition. Samples shall be taken from
the ingot or the extremes of the product to be analyzed.
6. Mechanical Properties
6.1 Material supplied under this specification shall conform to the mechanical property requirements given in Table 7 for the
grade specified.
6.2 Tension testing specimens are to be machined and tested in accordance with Test Methods E8. Tensile properties shall be
determined using a strain rate of 0.003 to 0.007 in./in./min through the specified yield strength, and then increasing the rate so as
to produce failure in approximately one additional minute.
6.3 For sheet and strip, the bend test specimen shall withstand being bent cold through an angle of 105° without fracture in the
outside of the bent portion. The bend shall be made on a radius equal to that shown in Table 7 for the applicable grade. The bends
are to be made in accordance with Test Method E290, using Method 1, Guided Bend Test described in paragraph 3.6, bent through
105°, and allowed to spring back naturally. The surface of the specimen must include the original material surface with no material
removal or surface conditioning, except corners may be rounded to a maximum radius of 0.032 in. (0.8 mm). The width of the
bend shall be at least 5 times the thickness. The test report shall, at minimum, indicate acceptable or unacceptable results.
7. Permissible Variations in Dimensions
7.1 Dimensional tolerances on titanium and titanium alloy material covered by this specification shall be as specified in Tables
1-6 and Tables 10-16, as applicable.
8. Finish
8.1 Titanium and titanium alloy sheet, strip, and plate shall be free of injurious external and internal imperfections of a nature
that will interfere with the purpose for which it is intended. Annealed material may be furnished as descaled, as sandblasted, or
as ground, or both sandblasted and ground. If shipped as descaled, sandblasted, or ground, the manufacturer shall be permitted to
remove minor surface imperfections by spot grinding if such grinding does not reduce the thickness of the material below the
minimum permitted by the tolerance for the thickness ordered.

9. Sampling for Chemical Analysis
9.1 Samples for chemical analysis shall be representative of the material being tested. The utmost care must be used in sampling
titanium for chemical analysis because of its great affinity for elements such as oxygen, nitrogen, and hydrogen. Therefore, in
cutting samples for analysis, the operation should be carried out insofar as possible in a dust-free atmosphere. Chips should be
collected from clean metal and tools should be clean and sharp. Samples for analysis should be stored in suitable containers.
10. Methods of Chemical Analysis
10.1 The chemical analysis shall normally be conducted using the ASTM standard test methods referenced in 2.1. Other industry
standard methods may be used where the ASTM test methods in 2.1 do not adequately cover the elements in the material or by
agreement between the producer and purchaser. Alternate techniques are discussed in Guide E2626.
11. Retests
11.1 If the results of any chemical or mechanical property test lot are not in conformance with the requirements of this
specification, the lot may be retested at the option of the manufacturer. The frequency of the retest will double the initial number
of tests. If the results of the retest conform to the specification, then the retest values will become the test values for certification.
Only original conforming test results or the conforming retest results shall be reported to the purchaser. If the results for the retest
fail to conform to the specification, the material will be rejected in accordance with Section 14.
12. Referee Test and Analysis
12.1 In the event of disagreement between the manufacturer and the purchaser on the conformance of the material to the
requirements of this specification, a mutually acceptable referee shall perform the tests in question using the ASTM standard
methods in 2.1. The referee’s testing shall be used in determining conformance of the material to this specification.
13. Rounding-Off Procedure
13.1 For purposes of determining conformance with this specification, an observed or a calculated value shall be rounded off
to the nearest “unit” in the last right-hand significant digit used in expressing the limiting value. This is in accordance with the
round-off method of Practice E29.
14. Rejection
14.1 Material not conforming to the specification or to authorized modifications shall be subject to rejection. Unless otherwise
specified, rejected material may be returned to the manufacturer at the manufacturer’s expense, unless the purchaser receives,
within three weeks of notice of rejection, other instructions for disposition.
15. Certification
15.1 The manufacturer shall supply at least one copy of the report certifying that the material supplied has been manufactured,
inspected, sampled, and tested in accordance with the requirements of this specification and that the results of chemical analysis,
tensile, and other tests meet the requirements of this specification for the grade specified. The report shall include results of all
chemical analysis, tensile tests, and all other tests required by the specification.
16. Marking and Packaging
16.1 Marking:
16.1.1 Identification—Unless otherwise specified in the purchase order, each plate, sheet, and strip shall be marked in the
respective location indicated below, with the number of this specification, heat number, manufacturer’s identification, and the
nominal thickness in inches. The characters shall be not less than ⁄4 in. (6.35 mm) in height, shall be applied using a suitable

marking fluid, and shall be capable of being removed with a hot alkaline cleaning solution without rubbing. The markings shall
have no deleterious effect on the material or its performance. The characters shall be sufficiently stable to withstand ordinary
handling.
16.1.2 Plate, flat sheet, and flat strip over 6 in. (152 mm) in width shall be marked in lengthwise rows of characters recurring
at intervals not greater than 3 in. (76 mm), the rows being spaced not more than 2 in. (51 mm) apart and alternately staggered.
Heat numbers shall occur at least 3 times across the width of the sheet and at intervals not greater than 2 ft (0.610 m) along the
length. As an option, when specified in the purchase order, each plate, sheet, or cut length strip may be marked in at least one
location with the number of this specification, heat number, manufacturer’s identification, and the nominal thickness in inches or
millimetres as required.
16.1.3 Flat strip 6 in. (152 mm) and under in width shall be marked near one end.
16.1.4 Coiled sheet and strip shall be marked near the outside end of the coil.
16.2 Packaging—Unless otherwise specified, material purchased under this specification may be packaged for shipment either
by boxing, crating, single boarding, burlapping, or with no protection in accordance with the manufacturer’s standard practice.
