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.
Abstract. This specification covers several different types of chemical passivation treatments for stainless steel parts. The treatments are the following: immersion treatment using nitric acid solutions, immersion treatment using citric acid solution, and electrochemical treatment.
Changes to the new 2013 Edition of A967/A967M can be found in the following areas: Section 1.5 (changed to combined Metric/US units), Revised Section 4.1 and added Section 4.3, Added Notes 2 and 3 to Sections 6 and 7, Revised Section 13.3, Combined Sections 14 through 19 into a new Section 14, Revised Section 22.1 (Now numbered 17.1) and added
A967 was developed for replacement of Mil QQ-P 35. As part of the development, the word "dissolved" appears to be accidental dropped in para. 7.2. for the description of clean water. ASTM offers descriptions of work items in the interest of openness, as well as to solicit input from interested stakeholders who may not be …
Solution strengths of 4-10% citric acid are specified for passivation treatments in ASTM A967. Specifications for passivation treatments for stainless steels. Traditionally the American standards have been used. These include: – ASTM A380 – Practice for Cleaning, Descaling and Passivating of Stainless Steel Parts, Equipment and Systems
ASTM A967. General industries use this standard to describe and control the passivation of stainless steel. Passivation is a process of making stainless steel more stainless than it would be if left alone. It is based on using an acid (nitric or citric) under highly controlled conditions to remove free iron particles from the surface and to help form a metal oxide …
ASTM A967 passivation standards apply to the passivation, cleaning and testing of Stainless Steel parts. ASTM A967 standards help industries to ensure safe and reliable passivation services using nitric acid immersion, citric acid immersion and electromechanical treatments such as Electropolishing.
