SA 387 Grade 22 is a chromium-molybdenum alloy steel grade developed for high-temperature and high-pressure service conditions. Supplied in plate and sheet form (sheet cut from plate), this material is extensively used in pressure vessels, boilers, and heat exchangers operating in elevated temperature environments. The 2.25% chromium and 1.0% molybdenum content provides excellent creep resistance, oxidation resistance, and long-term strength stability. Ladhani Metal Corporation is a trusted manufacturer, supplier, and exporter of SA 387 Grade 22 alloy steel plates and sheets. All materials are sourced from approved mills and supplied in normalized and tempered condition, ensuring consistent quality, dimensional accuracy, and full compliance with ASME SA 387 / ASTM A387 standards for pressure equipment. Forms Available: plate, sheet (cut from plate) Grades Available: SA 387 Grade 5, Grade 9, Grade 11, Grade 12, Grade 22 Chemical Composition (% – SA 387 Grade 22): • Carbon (C): 0.05 – 0.15 • Chromium (Cr): 2.00 – 2.50 • Molybdenum (Mo): 0.90 – 1.10 • Manganese (Mn): 0.30 – 0.60 • Silicon (Si): up to 0.50 • Phosphorus (P): ≤ 0.025 • Sulphur (S): ≤ 0.025 Mechanical Properties (SA 387 Grade 22 – typical, vary by thickness): • Tensile Strength: 415 – 585 MPa • Yield Strength: minimum 205 MPa • Elongation: minimum 18% Key Features: • Excellent strength retention at elevated temperatures • Superior creep resistance for long-term service • Good resistance to oxidation and hydrogen attack • Designed for high-pressure and high-temperature environments • Good weldability with controlled preheating and post-weld heat treatment • High structural stability and toughness Material Characteristics: SA 387 Grade 22 alloy steel is engineered for prolonged service under high temperature and pressure. The chromium content enhances oxidation and corrosion resistance, while molybdenum improves tensile strength and creep resistance. This grade offers a stable microstructure, making it suitable for critical pressure-retaining components. Applications: • Pressure vessels and boilers • Heat exchangers and condensers • Refinery and petrochemical equipment • Power plant components • Reactors, separators, and drums • Oil & gas and chemical processing units Conclusion: Ladhani Metal Corporation supplies high-quality SA 387 Grade 22 alloy steel plates and sheets for demanding industrial applications. With excellent chemical stability, reliable mechanical performance, and compliance with international standards, SA 387 Grade 22 remains a preferred material for high-temperature and high-pressure service.
