SA 387 Grade 5 is a chromium-molybdenum alloy steel grade designed for high-temperature and pressure service applications. Supplied in plate and sheet form (sheet cut from plate), SA 387 Grade 5 alloy steel is widely used in pressure vessels, boilers, and heat exchangers where reliable strength, good oxidation resistance, and stable performance at elevated temperatures are required. Its balanced chemical composition provides improved mechanical properties compared to carbon steels, making it suitable for demanding industrial environments. Ladhani Metal Corporation is a trusted manufacturer, supplier, and exporter of SA 387 alloy steel plates and sheets, including SA 387 Grade 5. 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 5 specification): • Carbon (C): 0.05 – 0.15 • Manganese (Mn): 0.30 – 0.60 • Silicon (Si): 0.50 max • Chromium (Cr): 0.50 – 1.00 • 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. 22 – 25% Key Features: • Good strength retention at elevated temperatures • Resistance to oxidation and hydrogen-induced damage • Good weldability with proper preheating and PWHT • Improved creep resistance over carbon steels • Stable mechanical properties under pressure service • Suitable for moderate to high-temperature environments Material Characteristics: SA 387 Grade 5 alloy steel combines chromium and molybdenum to enhance high-temperature strength, oxidation resistance, and long-term service stability. This grade is commonly selected for pressure-containing components operating at moderate to high temperatures, where dependable performance and compliance with pressure vessel codes are essential. Applications: • Pressure vessels and boilers • Heat exchangers and condensers • Refinery and petrochemical equipment • Power plant components • Reactors, separators, and drums • Oil & gas processing systems Conclusion: Ladhani Metal Corporation supplies premium-quality SA 387 Grade 5 alloy steel plates and sheets for high-temperature and pressure service applications.
