The Stainless Steel 440B Stud Bolts from Kyaw Stainless are well-known for their impressive corrosion resistance, strength, and outstanding finish, making them a reliable choice for clients in various sectors, including industrial, marine, and engineering, both in Myanmar and beyond.
These stud bolts are primarily made up of chromium (16–18%), carbon (0.75–0.95%), along with trace amounts of manganese, silicon, and molybdenum. This specific blend strikes a perfect balance between hardness, corrosion resistance, and wear resistance. Mechanically, these bolts showcase high tensile strength, remarkable hardness, and moderate impact toughness. They also offer solid resistance to mild acids and alkalis, ensuring they perform well even in high-stress or corrosive environments. The combination of robust mechanical properties and corrosion protection makes 440B an excellent choice for critical fastening applications.
