Andre Stainless is a well-respected manufacturer and supplier of stainless steel based in Pulau Ujong, Singapore. They specialize in high-quality Stainless Steel 317 Bolts, which are crafted for exceptional corrosion and chemical resistance. Renowned for their precision-engineered fasteners, Andre Stainless serves demanding industries like petrochemical, marine, food processing, and pharmaceuticals. These 317-grade bolts are built to meet international standards, ensuring reliable performance even in highly corrosive and high-temperature settings. With a commitment to durability, prompt delivery, and technical support, Andre Stainless offers tailored fastening solutions that guarantee long-lasting performance in both local and global markets.
Stainless Steel 317 Bolts are made up of iron, 18–20% chromium, 11–15% nickel, 3–4% molybdenum, and a maximum of 0.08% carbon. This alloy, rich in molybdenum, delivers outstanding resistance to pitting, crevice corrosion, and chemical attacks. The bolts boast a tensile strength of about 515 MPa, a yield strength of roughly 205 MPa, and an elongation of 35–40%, along with good creep and stress rupture resistance at high temperatures. Their impressive corrosion resistance makes 317 bolts particularly well-suited for environments with sulfuric, acetic, and other aggressive acids, outperforming standard 304 and 316 stainless steels in various chemical applications.
