Welcome to Maduka Metals, your trusted partner for premium stainless steel in Abuja. We are proud to supply high-grade Stainless Steel 1.4122 Square Bars, a material chosen by local fabricators and engineers for its exceptional resilience. Known for its excellent edge retention and toughness, this specific grade is ideal for demanding applications where both strength and corrosion resistance are non-negotiable. We ensure our stock meets the highest standards, providing you with a reliable foundation for projects that are built to last in Nigeria’s diverse climate.
Stainless Steel 1.4122 is a martensitic grade celebrated for its balanced composition, which includes chromium for good corrosion resistance and a higher carbon content that contributes to its notable hardness. After proper heat treatment, it achieves impressive mechanical properties, including high tensile strength and excellent wear characteristics. This combination makes it particularly tough and durable, allowing it to maintain a sharp edge and resist deformation under significant stress, which is why it’s often selected for cutting tools and high-wear components.

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.
The uses for these square bars are extensive, particularly in industries that demand durability and precision. They are expertly machined into essential components like blades for agricultural machinery, custom tools for local workshops, and parts for the food processing industry. Their corrosion resistance also makes them suitable for surgical instruments and various automotive applications. At Maduka Metals, we see our 1.4122 square bars forming the backbone of countless projects across Abuja, from robust industrial machinery to specialized architectural fittings that withstand the test of time.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
