Rinsing – spray and/or immersion must be thorough. Drying- this must immediately follow rinsing. The standards of ASTM A967 provide specific details of the acceptable methods required for passivating stainless steel. The passivation standards listed in the ASTM document embrace a variety of potential methods and techniques.

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 … بیشتر
