They offer ASME SA 387 Grade 11 Class 1 & Class 2 Sheets and Plates, crafted to meet rigorous ASME standards for strength, durability, and thermal stability. These plates are essential for critical industrial equipment that operates under both pressure and heat. Nizar Sheetsandplates is committed to maintaining strict quality control, ensuring precise dimensions, and adhering to international specifications.
ASME SA 387 Grade 11 is a chromium-molybdenum alloy steel that contains around 1.0–1.5% chromium and 0.45–0.65% molybdenum. This unique blend gives it impressive tensile and yield strength, along with enhanced creep and oxidation resistance at high temperatures. Class 1 plates come in a normalized state, while Class 2 plates are quenched and tempered, providing greater strength and toughness. Both classes are designed for excellent weldability when the right welding techniques are used.
