At Esha Steel, we proudly supply premium ASME SA 387 Grade 5 Class 1/2 Sheets and Plates to industries across Kolkata and nationwide. Manufactured according to ASME standards, these sheets and plates are engineered to provide reliable performance in high-temperature and high-pressure industrial applications. Esha Steel ensures precise dimensions, consistent quality, and superior mechanical properties. Trusted across power generation, petrochemical, and industrial sectors, Grade 5 Class 1/2 sheets and plates offer excellent toughness, heat resistance, and durability, making them ideal for boilers, pressure vessels, and heat exchangers in demanding industrial environments.
ASME SA 387 Grade 5 Class 1/2 Sheets and Plates are made from alloy steel containing controlled amounts of carbon, chromium, molybdenum, and manganese, along with small percentages of phosphorus, sulfur, and silicon. This composition provides excellent high-temperature strength, creep resistance, and corrosion resistance. Mechanically, the plates offer tensile strength of 485–620 MPa, yield strength of 260–415 MPa, and good elongation and impact toughness. Uniform microstructure and heat treatment enhance hardness, dimensional stability, and weldability, making these sheets and plates suitable for high-stress, high-temperature industrial applications.
