Chanchai Stainless is a well-known stainless steel manufacturer and supplier based in Bangkok, Thailand. They specialize in high-quality Stainless Steel 316L Nuts, which are built to last with exceptional durability and resistance to corrosion. The 316L grade is a low-carbon version of 316 stainless steel, making it easier to weld and less prone to sensitization during welding or high-temperature processes. With outstanding protection against pitting, crevice corrosion, and stress cracking from chlorides, these nuts are perfect for tough and corrosive settings. Chanchai Stainless takes pride in delivering reliable fastening solutions for various industries, including petrochemical, marine, pharmaceutical, food processing, and power generation.
Stainless Steel 316L Nuts are made up of 16–18% chromium, 10–14% nickel, and 2–3% molybdenum, with a lower carbon content that enhances weldability and prevents carbide precipitation. This unique blend gives them excellent resistance to chemical attacks, chloride corrosion, and acidic conditions. On the mechanical side, 316L nuts boast a tensile strength of about 485 MPa, a yield strength of 170 MPa, and impressive ductility for easy forming and fabrication. They retain their toughness, hardness, and resistance to oxidation, even at higher temperatures. With their enhanced stability against stress corrosion cracking, Stainless Steel 316L Nuts provide strong, secure, and long-lasting fastening performance in demanding environments.
