440FSE Stainless Steel
440FSE is a high carbon martensitic stainless steel that is AOD melted. This alloy is considered a free machining grade because of the added Selenium creating a better machinability version of similar grades 440A stainless and 440C stainless. This grade is suitable for non-galling and non-seizing applications. This alloy is often considered for general machined parts requiring higher hardness values than other free machining grades such as 420F.
