Based in the heart of Addis Ababa, Tariku Metals is a trusted name for industrial and construction materials, known for reliability and a deep understanding of local needs. We are proud to be your premier supplier for Stainless Steel 1.4122 flat bars, a robust martensitic grade chosen for its exceptional durability. This steel finds a perfect balance between strength and corrosion resistance, making it an ideal, cost-effective solution for demanding projects across Ethiopia, from heavy machinery to vital architectural components. Our commitment is to provide not just the product, but the expert support to ensure your project’s success.
Stainless Steel 1.4122 is a martensitic grade appreciated for its impressive strength and good resistance to corrosion. Its composition includes a higher carbon content along with chromium, which gives it a notable hardness and the ability to withstand wear and tear remarkably well. After proper heat treatment, it achieves high tensile strength, making these flat bars substantially more durable than standard carbon steels. This combination of properties means it can perform reliably in challenging environments where both mechanical stress and moderate corrosive elements are a factor.

Yes, Stainless Steel 1.4122 flat bars can be welded, though preheating and post-weld heat treatment may be necessary to reduce the risk of cracking and ensure optimal weld quality.
Yes, Stainless Steel 1.4122 flat bars can be heat treated. It is typically hardened by quenching and tempering, allowing control over hardness and strength for specific applications.
Stainless Steel 1.4122 flat bars resist corrosion due to their high chromium content, forming a passive oxide layer that protects the material from oxidation and corrosion in various environments.
The unique properties of 1.4122 flat bars make them incredibly versatile. You’ll often find them at work in the cutting edges of industrial blades, molds for plastic injection, and components for pumps and valves that face abrasive conditions. Within the construction sector, they are ideal for structural parts in aggressive environments, critical fasteners, and even components for mining equipment. Essentially, wherever an application demands a material that can stand up to significant mechanical pressure, friction, and a degree of corrosion, this steel grade proves to be an outstanding and dependable choice.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
