Aung Metals, a well-respected manufacturer and supplier located in Naypyidaw, Myanmar, specializes in high-quality **Stainless Steel 420 Square Bars and Rods**. These products are celebrated for their impressive hardness, wear resistance, and ability to fend off corrosion. Crafted with precision to meet international standards, they promise reliable performance across various industrial, mechanical, and tooling applications. Thanks to their high carbon and moderate chromium content, 420 stainless steel delivers exceptional hardness, edge retention, and durability, all while ensuring decent corrosion resistance. Aung Metals’ 420 Square Bars and Rods are perfect for tasks that demand strength, precision, and longevity, particularly in fields like tooling, engineering, and industrial machinery.
These Stainless Steel 420 Square Bars and Rods contain about 12–14% chromium and 0.15–0.40% carbon, along with trace amounts of manganese, silicon, and phosphorus. This unique blend results in high hardness, solid wear resistance, and moderate corrosion resistance. They boast impressive mechanical properties, including a tensile strength ranging from 600–800 MPa, yield strength between 275–450 MPa, and elongation of 15–25%. Their martensitic structure provides excellent toughness, fatigue resistance, and dimensional stability, making them ideal for high-stress, wear-intensive, and precision industrial applications.
