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 applications in industries that require exceptional hardness and strength. They are commonly used in the production of surgical instruments, bearings, valve parts, and pump components, thanks to their durability and wear resistance. In the automotive and engineering fields, they are utilized for dies, molds, and precision tools. The alloy’s ability to retain a sharp edge makes it ideal for crafting knives and cutlery. Furthermore, the defense and aerospace sectors rely on these bars and rods for specialized equipment, where strength, toughness, and a long service life are essential.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
