Résumé. 1.1 This specification covers several different types of chemical passivation treatments for stainless steel parts. It includes recommendations and precautions for descaling, cleaning, and passivation of stainless steel parts. It includes several alternative tests, with acceptance criteria, for confirmation of effectiveness of such ...
35A, AMS 2700C, ASTM A 967-05 and ASTM A 380-06 standards. Passivation alone will not remove heavy adherent oxide films created from heat treatment, welding, hot-forming and other high-temperature operations. Therefore AST uses different types of pickling acids designed to remove these films prior to the Passivation of the parts.
Scope. 1.1 This test method covers determination of compressive strength of cylindrical concrete specimens such as molded cylinders and drilled cores. It is limited to concrete having a density in excess of 800 kg/m 3 [50 lb/ft 3 ]. 1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard.
ASTM A967 and ASTM A380 have similar mechanical properties. Both materials have a yield strength of 205 MPa and a tensile strength of 520 MPa. The main difference is that ASTM A967 has a higher elongation at break (10%) than ASTM A380 (8%). This means that ASTM A967 is more ductile than ASTM A380 and is better suited …

The following spec refers to ASTM A380 for passivation of stainless steel and thus allows the use of ASTM A967: MIL-DTL-14072D/E/F (Table IV. Finish E300) The spec MIL-T-704K in section 3.2.6 directly describes a passivation process analogous to QQ-P-35's type II followed by a chromate post-treatment. However, QQ-P-35 assigns this process as ...

For example, ASTM A967 contains more options for passivation verification tests while AMS2700 provides more guidance on sampling large batches of components for testing and inspection after passivation. As the most direct linear descendant of QQ-P-35, AMS 2700 naturally shows its "heritage". QQ-P-35 types II, VI, VII and VIII are equivalent ...

ASTM A967 defines seven tests for verification that a suitable passive surface has been formed on the component surface. These tests are all qualitative. Although some tests can more precisely detect the amount of free iron remaining on a surface, they are meant to serve as a go, no-go test for passivation. Water immersion test.

A. ASTM A967 [affil link] is often specified for passivation of titanium, although it is a misnomer for sure. What you are removing by "passivation" of titanium is any iron or iron oxide that may have been put on the surface in the fabrication process of the parts. Even though you do not truly passivate the titanium metal itself, you need to ...

Both AMS 2700 and ASTM A967 base their nitric acid passivation methods on using 42° Baume nitric acid. The Baume scale is a measurement of specific gravity. Positive degrees of Baume indicate chemicals or solutions denser than water. 42° Baume nitric acid corresponds to a 1.4 specific gravity solution of nitric acid that is roughly 67% …
A. Suggested method is the High Humidity Test per ASTM A967 [affil link] practice B. It can be used on ALL metals and is non-toxic (versus the copper sulphate testing). An additional bonus is having an independent, (semi) local testing lab perform and certify the results. This method provides uniform exposure to entire surface area.
