Product Overview
Introduction To Engineering Steel P12
MOKSH TUBES & FITTINGS LLP is a leading manufacturer, supplier, exporter, importer, and stockist of P12 steel products including seamless and welded pipes, tubes, plates, and forgings.
EN P12, is a chromium-molybdenum alloy steel designed for high-temperature service, offering enhanced strength and corrosion resistance compared to P11 steel. It is commonly used in boilers, superheaters, and pressure vessels operating up to 565°C (1050°F). P12 provides improved creep resistance and toughness, making it suitable for more demanding thermal and mechanical conditions.
