Maduka Metals, a reputable manufacturer and supplier located in Abuja, Nigeria, has made a name for itself by producing top-notch **Stainless Steel 420 Rectangular Bars**. These bars are meticulously crafted using cutting-edge manufacturing techniques and high-quality raw materials, guaranteeing exceptional performance, durability, and finish. Stainless Steel 420, known for its high-carbon martensitic properties, is prized for its remarkable hardness and decent corrosion resistance. Maduka Metals offers these rectangular bars in a variety of sizes to cater to different industrial requirements, serving sectors like engineering, automotive, construction, and tooling with products that embody strength and reliability.
**Stainless Steel 420 Rectangular Bars** primarily consist of **iron**, along with **12–14% chromium**, **0.15–0.40% carbon**, and trace amounts of **manganese**, **silicon**, **phosphorus**, and **sulfur**. This type of martensitic stainless steel achieves impressive hardness and tensile strength after appropriate heat treatment, with values soaring between **700–850 MPa**. It also showcases good wear resistance and moderate corrosion protection in less aggressive environments. The chromium content boosts its resistance to oxidation, while the high carbon content enhances edge retention and mechanical strength, making it ideal for both precision and heavy-duty applications.
