Stainless Steel 1.4122 Hex Bars are martensitic stainless steels, primarily made up of about 12% chromium, along with molybdenum and carbon, which enhance their strength and hardness. This material boasts a high tensile strength of around 850–1000 MPa and good wear resistance, while also offering moderate corrosion resistance in mildly aggressive environments. These hex bars can be heat-treated for added hardness and are magnetic. Their machinability and mechanical stability make them a versatile option for applications that require both strength and moderate corrosion resistance.
