Alloy Steel Buttweld Fittings are made up of a blend of chromium, molybdenum, carbon, manganese, and silicon, which give them their impressive mechanical and thermal properties. The addition of chromium and molybdenum boosts their corrosion resistance, strength, and hardness, while a carefully controlled carbon content enhances weldability and toughness. These fittings showcase a tensile strength of about 415 MPa, a yield strength of 205 MPa, and an elongation of around 20%. Their robust mechanical performance ensures a long service life, excellent creep strength, and resistance to oxidation, even in high-temperature and high-pressure settings.
