At Esha Steel, we proudly offer premium ASME SA 387 Grade 12 Class 1/2 Sheet and Plates to industries across Kolkata and nationwide. Manufactured according to ASME standards, these sheets and plates are designed to withstand high temperatures, pressure, and demanding industrial conditions. Esha Steel emphasizes precision, quality, and timely delivery to ensure every product meets strict mechanical and chemical specifications. Trusted across petrochemical, power, and pressure vessel industries, our Grade 12 sheets and plates provide superior durability, corrosion resistance, and reliable performance in critical applications.
ASME SA 387 Grade 12 Class 1/2 Sheet and Plates are made from alloy steel with chromium (approximately 1%) and molybdenum additions, along with controlled carbon, manganese, phosphorus, and sulfur. This composition provides excellent heat resistance, corrosion resistance, and mechanical strength. Mechanically, the plates and sheets offer tensile strength ranging from 415–585 MPa, yield strength of 240–290 MPa, and good elongation. They also exhibit exceptional impact toughness and dimensional stability at elevated temperatures. These properties make them ideal for pressure vessels, boilers, and high-temperature process equipment.
