Abstract

Analyzing failure causes of the parts made of heat resistant steel shows that one of the defining factors impacting the properties is concentration of harmful impurities both dissolved in steel and being in the form of nonmetallic inclusions. The latter, in turn, is considerably defined by the process of steel deoxidation.
