440C / SS440C / UNS S44004 stainless steel is a member of the 400 series of stainless steel. It has the highest carbon content among them. The standout properties of this type of steel are its hardness, mechanical strength and fatigue resistance. This combination of properties makes it useful in the production of cutting tools. Due to its high carbon content, it does not have outstanding corrosion resistance, but it can still be used for applications that require moderate corrosion resistance such as surgical instruments. 440C is very similar to the 440B grade
