Alloy Steel Fittings
Alloy Steel Fittings are made from chromium-molybdenum alloy steel (Cr-Mo), designed for exceptional strength, durability, and performance in demanding environments. Manufactured as per ASTM A234 WP11, WP22, WP5, and WP91 standards, these fittings are suitable for boiler piping, oil & gas pipelines, refineries, and power plants. Alloy Steel Butt Weld, Socket Weld, and Forged Fittings deliver excellent heat resistance, corrosion protection, and pressure-handling capability, making them ideal for critical engineering applications.

Manufacturing Process
Our Alloy Steel Fittings are sourced from premium manufacturers that follow advanced forging and heat-treatment processes. High-quality Cr-Mo billets undergo forming, forging, and precision machining to meet ASTM and ASME standards. After shaping the fittings (elbows, tees, reducers, caps), they are subjected to heat treatment processes such as normalizing, annealing, and tempering to enhance strength and durability. CNC machining ensures dimensional accuracy, while each fitting undergoes rigorous testing including hydrotesting, tensile testing, PMI testing, and NDT inspection. As trusted alloy steel fittings traders, we deliver high-performance components suitable for boilers, refineries, power plants, chemical industries, and other critical applications.
