Rupal Metals is a well-known Indian manufacturer and supplier located in Delhi that supplies a variety of top-quality stainless steel products, such as Stainless Steel 1.4122 Square Bars. These square bars are known for their accurate precision engineering, excellent surface finish, and dimensional accuracy, and they are widely renowned across various industrial applications. Rupal Metals is focused on quality, consistency, and customer satisfaction, and hence it is a name to reckon with in the domestic and international markets. With state-of-the-art manufacturing units and highly qualified personnel, the organization provides better stainless steel solutions customized to suit the particular demands of engineering, fabrication, and structural usage.
Stainless Steel 1.4122 Square Bars are martensitic stainless steel bars containing mostly 12–14% chromium, supplemented with carbon, manganese, and minor fractions of silicon and phosphorus. These bars exhibit tensile strength of 800–1000 MPa, Brinell hardness of 250 HB at most. They have moderate corrosion resistance, good wear resistance, and excellent machinability in tempered condition. These steel grades can be heat treated for improving its mechanical properties and can be used in applications where strength, hardness, and moderate corrosion resistance are desired.

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.
1.4122 Stainless Steel Square Bars are extensively applied in automotive, mechanical engineering, and tooling sectors for parts such as spindles, shafts, and gears that require superior durability and strength. They can also be used for pump components, valve parts, and other fittings subject to mild corrosive environments due to their resistance to wear and moderate corrosion. These bars are most often used in the production of machine components subject to high stress, such as bushings and fasteners, where both hardness and machinability are required. Their easy versatility to heat treatment further extends their applications in other industrial processes.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
