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.
Stainless Steel 440C Bars and Rods find extensive use in industries that require high hardness, wear resistance, and corrosion resistance. In the realms of tooling and precision engineering, they are commonly used for cutting tools, dies, bearings, and knives. The automotive and aerospace industries utilize 440C bars and rods for shafts, gears, and components that endure high stress. In marine environments, they are essential as corrosion-resistant fasteners and parts exposed to harsh conditions. Furthermore, Stainless Steel 440C Bars and Rods are perfect for industrial machinery, medical instruments, and high-performance engineering applications where precision, strength, and longevity are crucial.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
