Kyaw Stainless, a reputable manufacturer and supplier located in Naypyidaw, Myanmar, specializes in high-quality Stainless Steel 309S Fasteners that are designed to perform exceptionally well in high-temperature and corrosive settings. These fasteners are crafted using cutting-edge technology and precise machining techniques, ensuring they boast remarkable strength, accurate dimensions, and long-lasting durability. Built to resist oxidation and scaling, Stainless Steel 309S Fasteners are perfect for critical industrial applications where reliability and longevity are a must. Kyaw Stainless guarantees that all products adhere to international quality standards, catering to industries like petrochemical, thermal power, cement, and chemical processing with trustworthy fastening solutions.
Stainless Steel 309S Fasteners are made up of chromium (22–24%), nickel (12–15%), and carbon (≤0.08%), along with trace amounts of manganese (≤2%), silicon (≤1%), phosphorus (≤0.045%), and sulfur (≤0.03%). The high levels of chromium and nickel in the alloy provide exceptional resistance to oxidation and corrosion, while the low carbon content improves weldability and minimizes carbide precipitation. In terms of mechanical properties, these fasteners deliver a tensile strength of about 515 MPa, a yield strength of 205 MPa, and an elongation of 40%. They maintain impressive structural stability, toughness, and strength even under thermal cycling and significant mechanical stress.
