Casting technology

Our cryogenic service valve castings are typically made of modified ASTM CF8M austenitic stainless steel which contains a higher percent nickel to minimize transformation of an austenitic structure to a martensitic structure. This undesirable transformation occurs when valve parts are machined during production process (or subjected to mechanical stress), which make them vulnerable to distortion, when valve assemblies are exposed to extremely low temperature in the field. This must be prevented during production because of subsequently degraded seat face precision, and resultant concern of seat leakage. By the way, a higher nickel content usually lowers the temperature where martensitic transformation begins (Martensitic Transformation Temperature or MTT in short, only in this article below). For this reason, our foundries always ensure proper adjustment of other chemicals such as carbon and chromium to make MTT lower.
