Question

Carbon pickup during the production of austenitic stainless steels has caused premature failures of intergranular corrosion.

(a) True

(b) False

The question was posed to me in an interview.

The question is from Eight Forms topic in chapter Eight Forms of Corrosion of Corrosion Engineering

Answer 1

Right option is (a) True

The explanation is: Carbon pickup or surface carburization during the production of austenitic stainless steel has caused premature failures. It occurs when these steels are cast into molds that contain carbonaceous materials such as organic binders and baked oil sand. It reduces the corrosive resistance of these steels in the viewpoint of intergranular attack.
