Aung Metals, a well-respected manufacturer and supplier located in Naypyidaw, Myanmar, specializes in high-quality **Stainless Steel 420 Rectangular Bars**. These bars are celebrated for their impressive hardness, wear resistance, and ability to fend off corrosion. Each rectangular bar is meticulously crafted to adhere to international standards, guaranteeing dependable performance in various industrial, mechanical, and tooling applications. With a blend of high carbon and moderate chromium, 420 stainless steel delivers exceptional hardness, edge retention, and durability, all while offering decent corrosion resistance. Aung Metals’ 420 Rectangular Bars are perfect for tasks that demand strength, precision, and longevity, making them ideal for cutting tools, machinery components, and high-stress industrial applications across a range of engineering fields.
These Stainless Steel 420 Rectangular Bars contain about 12–14% chromium, 0.15–0.40% carbon, along with trace amounts of manganese, silicon, and phosphorus. This unique composition results in high hardness, solid wear resistance, and moderate corrosion resistance. They boast impressive mechanical properties, including a tensile strength of 600–800 MPa, yield strength of 275–450 MPa, and elongation of 15–25%. Thanks to their martensitic microstructure, these bars offer excellent toughness, fatigue resistance, and dimensional stability, making them well-suited for high-stress, wear-intensive, and precision applications in industrial settings.
