Stainless Steel 1.4122 Bars are celebrated for their remarkable blend of strength, hardness, and resistance to corrosion, making them a go-to choice for a variety of engineering and industrial tasks. As a martensitic stainless steel grade, akin to AISI 420, 1.4122 boasts impressive wear resistance, polishability, and dimensional stability. These bars shine in environments where durability and moderate corrosion protection are key. Their excellent machinability and heat-treatable properties make them perfect for crafting precision components. With reliable performance and versatility, Stainless Steel 1.4122 bars find their way into mechanical, automotive, and tool manufacturing industries.
The composition of Stainless Steel 1.4122 Bars primarily includes chromium (around 12–14%), with carbon levels fine-tuned for enhanced hardness and strength. This alloy achieves a tensile strength of approximately 700–850 MPa and a yield strength of about 450–550 MPa when tempered. After heat treatment, it showcases good hardness and dependable resistance to wear, abrasion, and mild atmospheric corrosion. The material maintains stable mechanical properties under stress and offers solid machinability in both annealed and tempered states, making it ideal for demanding engineering applications that require strength and durability.
