They are produced to make supreme quality carbon steel plates intended for use in welded pressure vessels where notch toughness is important. The steel is killed and can be normalized as it conforms to fine austenitic grain size requirements. Boiler Quality plates are available in various grades that cover a range of tensile strengths, and its versatility explains much of the specification’s popularity. Since boilers and pressure vessels carry high pressure and temperature fluids, and hold low- temperature fluids as well, the steel plates ought to have properties like high strength, toughness, ductility and resistance to corrosion.
ISEPL maintains superior Boiler Quality (BQ) Steel Plates that can withstand the internal pressure of valves and boilers. Our clients repeatedly prefer us for the longevity and durability of our products. We supply BQ Plates of Domestic and Imported Make manufactured by the finest mills around the globe. They comply with various Indian and International Standards to meet different segment requirements. We also offer Cut-to-Length plate services to our customers in special cases.
