WebMaraging steel 350 refers to crystalline tempered steel. Martensite, which is created through an aging process. When aging is used, steel is forced to cool from its molten state to its solid state over a prolonged period of time. The result is a metal that is harder and stronger than it would be had the steel been allowed to cool at a natural rate. WebIntroduction. Ferritic, martensitic and duplex stainless steels tend to become brittle as the temperature is reduced, in a similar way to other ferritic / martensitic steels. The austenitics stainless steels such as 304, (1.4301), and 316, (1.4401), are however ‘tough’ at cryogenic temperatures and can be classed a ‘cryogenic steels’.
