                      440C Stainless Steel Sheet
                      9Cr18 is a kind of martensitic steel which contains high carbon and high chromium. After quenching, 9Cr18 has relatively high hardness and wearing resistance. 9Cr18 also has stable temper resistance. We use LF furnace refining after electric furnace smelting so as to ensure the purity and uniformity of the steel. The steel ingot will be forged after annealing by appropriate forging process and ratio so as to refine particles、change inclusion morphology、forge together the internal defects、eliminate segregation. Thus, the mechanical property of the steel can be improved dramatically.
