Kyaw Stainless is a well-respected manufacturer and supplier located in Naypyidaw, Myanmar, specializing in top-notch Stainless Steel 309H Forged Fittings. These fittings are designed to excel in high-temperature and corrosive industrial settings. Renowned for their remarkable strength, durability, and resistance to oxidation, the Stainless Steel 309H Forged Fittings are crafted using cutting-edge forging techniques and adhere to strict quality standards. Kyaw Stainless guarantees precise dimensions, a superb surface finish, and dependable mechanical properties, making these fittings perfect for applications in power generation, petrochemicals, and furnaces where heat and corrosion resistance are crucial.
The composition of Stainless Steel 309H Forged Fittings includes about 22–24% chromium, 12–15% nickel, and a higher carbon content (up to 0.12%) compared to standard 309 grades, along with small amounts of manganese, silicon, and phosphorus, with iron making up the rest. This unique blend boosts their creep strength and oxidation resistance at high temperatures. These fittings boast a tensile strength of around 515 MPa and a yield strength of about 205 MPa, along with good ductility, toughness, and structural stability. Their elevated carbon content helps them retain strength and hardness even when exposed to prolonged heat.
