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 strength, hardness, and wear resistance. They are particularly well-suited for applications such as bearings, valve components, pump shafts, fasteners, cutting tools, and knife blades. Their superior resistance to corrosion and wear makes them ideal for sectors like aerospace, marine, petrochemical, and automotive. Additionally, these bars and rods are employed in medical instruments, molds, dies, and precision machinery parts where durability and dimensional accuracy 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.
