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 demand exceptional hardness and wear resistance. They are perfect for crafting precision components like bearings, shafts, valves, cutting tools, and knife blades. Their impressive corrosion resistance and ability to keep a sharp edge make them ideal for marine and chemical processing equipment. Moreover, 440C rods are widely utilized in aerospace, automotive, and medical fields where performance and durability are paramount. Phehlukwayo Metal provides these bars and rods in tailored dimensions to meet specific industrial requirements, ensuring dependable and long-lasting performance in challenging environments.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
