Alloy Steel Buttweld Fittings typically contain a combination of chromium (2.25%), molybdenum (1%), and small amounts of carbon, manganese, silicon, phosphorus, and sulfur. This composition provides enhanced resistance to high temperatures, oxidation, and corrosion. The mechanical properties include a tensile strength of 485 MPa (min), yield strength of 205 MPa (min), and elongation of 30% (min). These fittings offer excellent durability and strength, making them ideal for high-pressure and high-temperature environments. Their superior thermal stability and resistance to wear make them suitable for applications in power generation, petrochemical, and oil & gas industries.
