Stainless Steel 1.4122 Square Bars are martensitic stainless steels containing approximately 12% chromium, 1% molybdenum, and controlled carbon content, which enhance hardness, strength, and corrosion resistance. These bars exhibit tensile strength ranging from 700 to 950 MPa and yield strength around 500 MPa, with excellent wear resistance and good machinability. They also provide moderate corrosion resistance in mildly aggressive environments while maintaining high mechanical stability. With good hardenability and tempering properties, Stainless Steel 1.4122 Square Bars are widely used in precision components, tools, and mechanical applications requiring toughness, durability, and long service life.

Yes, Stainless Steel 1.4122 square bars can be heat treated. They are typically hardened and tempered to enhance strength and wear resistance, with tempering temperatures ranging between 200°C and 400°C depending on desired properties.
Consider factors like required strength, corrosion resistance, wear resistance, application environment, dimensional accuracy, thermal properties, compliance with industry standards, and suitability for machining or heat treatment when choosing Stainless Steel 1.4122 square bars.
Yes, Stainless Steel 1.4122 square bars can be welded, but they require preheating to around 200-300°C and post-weld heat treatment to reduce residual stresses and maintain mechanical properties.
Stainless Steel 1.4122 Square Bars are extensively used in industries requiring high strength, wear resistance, and reliable machinability. They are applied in the production of automotive components, shafts, spindles, and machine parts where durability and performance are critical. In addition, they are used for making surgical instruments, knives, and cutting tools due to their hardness and moderate corrosion resistance. Mechanical engineering, construction, and tool-making industries also benefit from their versatility. Their combination of toughness, machinability, and wear resistance makes Stainless Steel
