Stainless Steel 440C Bars and Rods are known for their high hardness, achieving up to 58-60 HRC when heat-treated. This makes them ideal for applications requiring excellent wear and abrasion resistance.
Stainless Steel 440C offers good corrosion resistance in mild environments, but for more aggressive conditions (like exposure to saltwater), it is recommended to use more corrosion-resistant stainless steel grades like 316 or 317.
Aung Metals’ Stainless Steel 440C Bars and Rods find extensive use in industries where hardness, wear resistance, and corrosion protection are paramount. They are ideal for crafting bearings, bushings, shafts, knives, cutting tools, and precision instruments. Additionally, they serve in fasteners, mechanical assemblies, and wear-resistant components that face friction and stress. Their unique combination of hardness, corrosion resistance, and dimensional stability guarantees a long service life, reliability, and high performance in challenging industrial, mechanical, and tooling applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
Aung Metals is a leading manufacturer, supplier, and exporter of high-quality bars, rods, and forgings, catering to various industries in Naypyidaw, Myanmar
