Welcome to Maduka Metals, your trusted partner for premium stainless steel right here in Abuja. We take pride in supplying robust materials that fuel the growth of Nigerian industry, and our Stainless Steel 1.4122 bars are a perfect example. Known for its excellent durability, this grade is engineered to withstand demanding environments, offering superior performance for critical projects. We understand that quality materials are the foundation of lasting work, which is why we ensure our 1.4122 bars meet the highest standards for professionals who won’t settle for less.
This particular grade, often called 420C, is a martensitic stainless steel valued for its balanced composition. It contains a higher carbon content alongside chromium, which gives it notable hardness and impressive resistance to wear and corrosion. After the appropriate heat treatment, these bars develop exceptional mechanical strength, making them remarkably tough and durable. This combination of properties means they can handle significant stress and abrasive conditions without degrading, ensuring a long service life even in challenging situations.

Yes, Stainless Steel 1.4122 bars can be recycled after use. Stainless steel is highly recyclable, retaining its properties and reducing environmental impact, making it a sustainable material for reuse.
Yes, Stainless Steel 1.4122 bars can be welded. It is weldable using standard methods like TIG or MIG welding, though pre-heating and post-weld heat treatment may be required for optimal results.
Yes, Stainless Steel 1.4122 bars can be heat treated. It can be hardened through quenching and tempering processes, improving strength and wear resistance while maintaining its corrosion resistance properties.
You’ll find these versatile bars at the heart of many demanding applications across various sectors. They are ideal for manufacturing essential cutting tools, surgical instruments, and high-stress components like valve parts and pump shafts. In the oil and gas industry, their corrosion resistance is crucial for specific tools and machinery components. Beyond that, they are perfectly suited for creating durable moulds, dies, and even high-quality kitchen cutlery, proving their worth anywhere strength, edge retention, and reliability are non-negotiable for success.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
