Alloy Steel Socket Weld Full Coupling
Built for high-temperature, high-pressure small-bore piping
Alloy Steel Forged Fittings are made by adding chromium and molybdenum to carbon steel, giving them improved strength, hardness and resistance to heat and creep. Forged construction further enhances their reliability in boiler lines, refinery units and power plant piping operating at elevated temperature and pressure.
Royal Steel India manufactures Alloy Steel Forged Fittings in F5, F9, F11, F22 and F91 grades, tested and certified for critical high-temperature service.

Frequently Asked Questions
Where are Alloy Steel Forged Fittings used?
They are used in high-temperature and high-pressure piping such as boiler feed lines, refinery process units, power generation plants and petrochemical piping.
Which grades of Alloy Steel Forged Fittings do you supply?
We supply ASTM A182 F5, F9, F11, F22 and F91 grade alloy steel forged fittings.
Why choose alloy steel over carbon steel for high-temperature fittings?
Alloy steel retains its strength and resists creep at temperatures where plain carbon steel would soften and fail, making it safer for critical high-temperature service.
