440 steel is a series of high-carbon martensitic stainless steels, including grades 440A, 440B, and 440C. Known for their excellent hardness and wear resistance, these steels are commonly used in the production of high-performance knives and cutting tools.
440 steel is part of the stainless steels or those alloy steels which contain a minimum of 10% chromium, imbuing these alloys with increased resistance to corrosion. The AISI has created a three-digit naming index for the stainless steels (as opposed to the typical four-digit names given to other, non-stainless steels), where the first digit repres...
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 excel...
