Aung Metals, based in Naypyidaw, Myanmar, is a top-notch manufacturer and supplier known for its high-quality **Stainless Steel 440C Square Bars and Rods**. These products are celebrated for their remarkable hardness, wear resistance, and ability to withstand corrosion. Each bar and rod is meticulously crafted to meet international standards, ensuring they perform exceptionally well in tough environments where durability and strength are a must. Thanks to their high carbon and chromium content, 440C stainless steel offers outstanding hardness and edge retention, making it perfect for parts that face friction and wear. Aung Metals’ 440C Square Bars and Rods find their place in various industrial, mechanical, and tooling applications, delivering reliable and long-lasting performance.
These Stainless Steel 440C Square Bars and Rods contain around 16–18% chromium and 0.95–1.2% carbon, along with trace amounts of manganese, silicon, and molybdenum. This unique blend gives them impressive hardness, corrosion resistance, and wear resistance. They boast mechanical properties like a tensile strength ranging from 760 to 1,000 MPa, hardness levels of 58–60 HRC, and moderate ductility, striking a great balance between toughness and strength. The martensitic structure of the material ensures excellent edge retention and fatigue resistance, making it a great choice for high-stress and high-wear industrial components.

Yes, Stainless Steel 440C Square Bars are magnetic. This is because they are martensitic stainless steel, which contains a high amount of carbon, making them ferromagnetic.
Yes, Stainless Steel 440C square rods can be heat-treated to improve hardness and strength. The typical heat treatment process includes austenitizing, quenching, and tempering.
Stainless Steel 440C square bars offer excellent high-temperature strength and maintain their hardness and wear resistance in elevated temperatures. However, prolonged exposure may lead to some reduction in toughness and ductility.
Aung Metals’ Stainless Steel 440C Square Bars and Rods are widely utilized in industries where hardness and wear resistance are crucial. They’re perfect for crafting bearings, valves, knives, cutting tools, and precision instruments. Additionally, they serve well in shafts, fasteners, and wear-resistant components for machinery that operates under significant stress. The combination of corrosion resistance, hardness, and dimensional stability makes these bars and rods ideal for marine, chemical, and industrial applications, guaranteeing long-lasting performance and reliability even in challenging conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
