Varun Sheets and Plates stands out as a top-notch manufacturer and supplier of Boiler Quality (BQ) Sheets and Plates in Dubai, UAE. We specialize in high-strength steel products tailored for pressure vessels and high-temperature applications. Our BQ sheets and plates are crafted to meet international standards like ASTM A516 / ASME SA516, DIN 17155, and IS 2002, guaranteeing exceptional reliability, weldability, and mechanical performance even under intense pressure and heat. With options like A516 Gr 60/70, we serve a variety of industries across the UAE and the GCC, including power plants, petrochemicals, refineries, and thermal energy projects, all with precision and consistency.
Boiler Quality Sheets and Plates are crafted from carbon steel alloys, mainly in grades such as ASTM A516 Grade 60/70. Their typical composition includes carbon (≤0.30%), manganese (0.79–1.30%), phosphorus (≤0.035%), and sulfur (≤0.035%). These plates boast impressive mechanical properties, featuring a tensile strength of 485–620 MPa, yield strength of 260–300 MPa, and an elongation of 20% or more, depending on thickness. Engineered for notch toughness and resistance to brittle fracture, BQ plates can endure high pressure and temperature cycles, making them perfect for welding and forming in pressure vessel fabrication.
