The ASTM A967 passivation standard applies to the cleaning, passivation and testing of stainless steel parts. Chemical passivation removes free iron and other surface contaminants from stainless steel parts, improving corrosion resistance. Stainless steel passivation performed to the ASTM A967 standards meets these standards by passing …

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 B 117 salt spray testing for 2 to 3 hours, and then evaluated for signs of red rust. Red rust is considered a failure for passivation. In addition, the stainless steel test specimens were also examined for signs of IGA (intergranular attack) and pitting after being treated in the optimized nitric, optimized citric acid, and 3

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.

ASTM B600 [affil link] is the proper standard for cleaning and descaling titanium alloys. Toby Padfield Automotive module supplier - Michigan 2005. 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 ...

1. Passivation Process: ASTM A967 defines the passivation process as the removal of free iron or other foreign matter from the surface of stainless steel by means of a chemical treatment. This treatment encourages the formation of a passive oxide layer, strengthening the steel's resistance to corrosion. 2.

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 ...

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.
