ASTM A387 Grade 22 plates are manufactured by using supreme quality raw material & high technology. It has a wide range of specifications such as different standards, hardness, form, finishing, thickness. A387 Grade 22 plate can work at 600°C temperature. Chromium and molybdenum work continuously at different temperatures with excellent performance. ASTM A387 gr 22 plate class 2 has benefits such as flawless finish, corrosion-resistant, good durability high-temperature resistance, high performance, high strength & efficiency, Flawless Finish, and weldability.
ASTM A387 Gr 22 class 1 is mainly intended for welded boilers and pressure vessels designed for elevated temperature services. ASTM A387 gr 22 class boiler steel plate is under steel standard specification, they can carry high pressure and temperature fluids and hold low- temperature fluids as well due to its properties like toughness, high strength, ductility, and resistance to corrosion. It is very popular due to its diversity of use and longevity.
