SA 387 Grade 11 is a chromium-molybdenum alloy steel grade developed for pressure vessels and equipment operating at elevated temperatures. Supplied in plate and sheet form (sheet cut from plate), SA 387 Grade 11 alloy steel provides excellent high-temperature strength, good oxidation resistance, and improved creep resistance, making it suitable for severe service conditions in power plants, refineries, and petrochemical industries. Ladhani Metal Corporation is a reliable manufacturer, supplier, and exporter of SA 387 alloy steel plates and sheets, including SA 387 Grade 11. Our materials are sourced from approved mills and supplied in normalized and tempered condition, ensuring consistent quality, dimensional accuracy, and full compliance with ASME / ASTM standards for pressure vessel and high-temperature applications. Forms Available: plate, sheet (cut from plate) Grades Available: SA 387 Grade 5, Grade 9, Grade 11, Grade 12, Grade 22 Chemical Composition (% – as per SA 387 Grade 11 specification): • Carbon (C): 0.05 – 0.15 • Manganese (Mn): 0.30 – 0.60 • Silicon (Si): 0.50 max • Chromium (Cr): 1.00 – 1.50 • Molybdenum (Mo): 0.45 – 0.65 • Phosphorus (P): ≤ 0.025 • Sulphur (S): ≤ 0.025 Mechanical Properties (Typical, vary by thickness): • Tensile Strength: approx. 415 – 585 MPa • Yield Strength: approx. 205 MPa • Elongation: approx. 20 – 24% Key Features: • Excellent strength and stability at elevated temperatures • Improved oxidation and corrosion resistance • Enhanced creep resistance for long-term service • Good weldability with proper preheating and PWHT • Reliable mechanical performance under pressure • Suitable for high-temperature and high-pressure environments Material Characteristics: SA 387 Grade 11 alloy steel contains higher chromium content compared to Grade 5, providing better oxidation resistance and thermal stability at elevated temperatures. The addition of molybdenum improves creep resistance and high-temperature strength, making this grade ideal for critical pressure-containing components. Applications: • Pressure vessels and boilers • Heat exchangers and condensers • Refinery and petrochemical equipment • Power plant components • Reactors, drums, and separators • Oil & gas and process industry units Conclusion: Ladhani Metal Corporation supplies premium-quality SA 387 Grade 11 alloy steel plates and sheets for demanding high-temperature and pressure service applications. With verified chemical composition, dependable mechanical properties, and strict compliance with international standards, SA 387 Grade 11 remains a preferred material for critical industrial equipment.
