440c stainless steel flat bar for sale

        440C steel is a martensitic stainless steel.Carbon content is 1.0%,chromium content is 16-18%.It has strong rust resistance and is high-quality stainless steel.



        440:High-strength cutting tool steel with slightly higher carbon content.After proper heat treatment,higher yield strength can be obtained.The hardness can reach 58HRC,which is among the hardest stainless steels.The most common application example is "razor blades".There are three commonly used models:440A,440B,440C,and 440F (easy processing type).

        Scope of application:Mainly used to manufacture bearing parts that work in corrosive environments and non-lubricated strong oxidizing atmospheres.440C has good high temperature dimensional stability,so it can also be used as corrosion resistant high temperature bearing steel.In addition,it can also be used to manufacture high-quality knives, such as medical scalpels, scissors, nozzles, bearings, etc.440C has low dynamic load capacity
