The ASTM A387 Grade 12 Plates are popularly known and considered the most commonly used in those applications which require high-temperature service within the industrial material scenario. These sets of plates have been obtained from the development of chrome-molybdenum alloy steel, which depicted high mechanical attributes, resistance to corrosion, and adaptability against various manufacturing processes. A and M Industries is proud to boast about ourselves as one of the leading manufacturing companies and suppliers of these excellent plates, making sure our clients get only the best.

The ASTM A 387 specification covers chromium-molybdenum alloy steel plates for welded boilers and pressure vessels. GR. 12 refers specifically to the grade that includes within its nominal composition 1% molybdenum and 1.25% chromium, hence becoming an excellent material for applications involving high temperatures. It has special properties that enable this alloy to preserve structural integrity and resist oxidation in service, even at very high temperatures, which makes it a must in the power generation, petrochemical, and chemical processing industries.
