440 steel can be found in most machine shops, as it is an easy metal to machine when annealed and yet is strong and resilient when heat treated. This material is exceptionally good for components that must resist corrosion relatively well and yet not wear under repeated use. It is a great steel for knife edges, as its hardness yet formability excels when used for kitchen cutlery. There are some other notable applications of 440 steel, listed below:
1.Mold and dies
2.Valve components
3.Instruments/measurement devices
4.Textile components
5.Ball bearings
