Alloy Steel WP91 Buttweld Fittings consist primarily of chromium (8-9.5%), molybdenum (0.85-1.05%), and carbon, with trace amounts of manganese, silicon, and nickel. This balanced mixture provides superior corrosion resistance, strength at elevated temperatures, and durability. From a mechanical perspective, these fittings demonstrate superior tensile and yield strength, outstanding hardness, and superior creep resistance at high temperatures. Meeting ASTM A335 and ASME SA234 specifications, WP91 fittings possess superior thermal stability and toughness with reliable performance and extended service life even in the most challenging industrial conditions.
