What is ASTM A967 Passivation? The ASTM A967 passivation standard applies to the cleaning, passivation and testing of stainless steel parts. Per passivation standard, ASTM A967 requires the parts to be immediately neutralized post immersion followed by a chemical treatment to treat the surface of the part. ASTM approved tests may include:

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 …

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 …
