Boiler Plate is hot‑rolled special pressure‑vessel steel plate dedicated for boilers and pressure‑bearing equipment. Featuring outstanding high‑temperature resistance, high‑pressure resistance, creep‑impact resistance and excellent weldability, Boiler Plate withstands long‑term alternating high‑temperature and high‑pressure loads, serving as indispensable special pressure‑bearing steel for power‑station boilers, industrial boilers, pressure vessels and heat‑exchange equipment manufacturing. Boiler Plate is mainly divided into Boiler Steel Plate and Pressure‑Vessel Boiler Plate. Different materials and specifications ofBoiler Plate adapt to power‑station steam drums, boiler furnaces, heat‑exchange cylinders, chemical storage tanks, reactors and thermal‑power equipment. With complete material grades and special‑equipment certificates available,Boiler Plate supports flame cutting, plasma blanking, sandblasting‑painting pretreatment, Z‑direction property customization and normalizing‑tempering heat‑treatment deep processing. As core pressure‑bearing material for boiler bodies with strict chemical‑composition control and full UT inspection grades, Boiler Steel Plate is the most versatileBoiler Plate. Used for high‑pressure vessels and chemical pressure‑bearing tanks, Pressure‑Vessel Boiler Plate delivers stable high‑temperature mechanical performance to guarantee long‑term safe operation of pressure‑bearing equipment. Conventional thickness of Boiler Plate ranges 6‑150mm, width 1500‑4500mm, length 4000‑18000mm. Main grades include Q245R, Q355R, 15CrMoR, 12Cr1MoVR, P265GH, SA516Gr70. Delivery states: hot‑rolled, normalized, tempered. Every plate passes tensile test, high‑temperature impact test and full‑coverage UT ultrasonic inspection. All Boiler Plate comply with GB/T713.2‑2023 national standard as well as EN10028, ASTM A516 foreign‑trade standards. Boiler plants and pressure‑vessel manufacturers can select Boiler Steel Plate and Pressure‑Vessel Boiler Plate according to working temperature, pressure‑bearing grade and equipment design specifications, giving full play to advantages of high‑temperature & high‑pressure resistance, good toughness and reliable weldability of Boiler Plate to ensure safe production and operation of pressure‑bearing equipment.
