Martensitic steel represents one of the most versatile and high-performing families of stainless steels, prized by manufacturing engineers for its exceptional strength, wear resistance, and ability to be hardened through heat treatment. First discovered in 1912 by Harry Brearley of Sheffield, England—who was originally seeking a corrosion-resistant alloy for gun barrels—martensitic stainless steel has since…
Grade 440C stainless steel represents the pinnacle of hardness and wear resistance among all stainless steel grades. As a high-carbon martensitic stainless steel, it has earned its reputation as the go-to material for applications requiring exceptional strength, durability, and the ability to maintain a sharp edge under demanding conditions. From precision ball bearings in critical…
