ASTM A967/A967M-17 Chemical Passivation Treatments for Stainless Steel Parts

Scope:

ASTM A967/A967M-17 test method covers the characteristics of stainless steel. The method proceeds with the quality check, heat treatment, and testing of the chemical composition of the material. The results obtained from this method help in quality control, research, mixing, and placing operations; determination of compliance with specifications; control for evaluating the effectiveness of admixtures; and performance evaluation of stainless steel.

Procedure:

The method covers the passivation treatment of stainless steel. The specimen parts are treated with nitric acid, citric acid, and electrochemical solutions. The parts then undergo rinsing and neutralization. The post-cleaning treatments include water immersion test, high humidity test, salt spray test, copper sulfate test, potassium ferricyanide nitric acid test, damp cloth test, and boiling water immersion test.

Specimen Size:

Specimen size should be as per the requirements. In this case, the parts can be of any length that can be submerged in the specific solution volumes.

Data:

The stainless steel parts undergo passivation treatment in the presence of specified volumes of nitric acid, citric acid, and electrochemical solutions.

Conclusion:

ASTM A967/A967M-17 test method is specifically important for the quality assurance and durability check of stainless steel. The top service provider in this regard is the Infinita Lab which ensures efficient and reliable testing.
