We manufacture forging ingots, billets, and blooms in ASTM A182 F22 Steel, a chromium-molybdenum low alloy steel developed for high-temperature and high-pressure service.
The combination of chromium and molybdenum provides excellent elevated-temperature strength, creep resistance, oxidation resistance, and long-term thermal stability.
ASTM A182 F22 is widely used for manufacturing forged flanges, forged fittings, valves, shafts, fasteners, pressure vessel components, and piping systems for power plants, refineries, petrochemical plants, oil & gas facilities, and heavy engineering industries where superior mechanical performance under elevated temperatures is required.

| Carbon (C) | 0.05 – 0.15 | Provides strength while maintaining good weldability |
| Manganese (Mn) | 0.30 – 0.60 | Improves toughness and hardenability |
| Silicon (Si) | Max. 0.50 | Improves strength and acts as a deoxidizer |
| Chromium (Cr) | 2.00 – 2.50 | Improves oxidation resistance, corrosion resistance, and elevated-temperature strength |
| Molybdenum (Mo) | 0.87 – 1.13 | Enhances creep resistance and high-temperature performance |
| Phosphorus (P) | Max. 0.030 | Controlled impurity for improved toughness |
| Sulphur (S) | Max. 0.030 | Controlled impurity for better machinability |
| Iron (Fe) | Balance | Base metal |
(Properties may vary depending on section size and heat treatment conditions.)
