Chanchai Stainless provides Stainless Steel 440C Bolts in Bangkok, Thailand. These bolts are crafted for maximum strength, hardness, and wear resistance. As a high-carbon martensitic stainless steel, 440C has the highest hardness among stainless steels, making these bolts ideal for heavy-duty fastening in mechanical and industrial applications. They combine moderate corrosion resistance with exceptional toughness and durability, especially when heat-treated. Chanchai Stainless manufactures 440C Bolts to strict quality standards, offering secure fastening solutions for industries needing high performance, abrasion resistance, and mechanical strength in tough settings. Chanchai Stainless, Bangkok, Thailand, has been recognized as a supplier of superior stainless steel products to the various industrial requirements. We believe in delivering durable solutions with the highest quality standards and customer satisfaction. Among the products we specialize in is the SS 440C Bolt, which offers high strength coupled with excellent resistance to wear due to its increased carbon content. These bolts are perfect for demanding applications where hardness and wear resistance are crucial. We are committed to supplying products that combine excellence, performance, and long-term reliability.
Stainless Steel 440C bolts contain chromium (16–18%), carbon (0.95–1.20%), and molybdenum (~0.75%). Heat treatment allows hardness up to 58–60 HRC, with a tensile strength around 760–950 MPa and a yield strength of about 450 MPa. While their corrosion resistance is lower than austenitic grades, it remains adequate in mild conditions. 440C provides superior wear resistance, mechanical strength, and stability, making it ideal for high-strength fasteners.
