Q550D Application: This steel is mainly used in steam turbines for main steam pipes with steam parameters up to 540℃, turning guide vane ring, steam turbine baffle, baffle outer ring, and various superheater tubes, ducts and pipes with tube wall temperature ≤570℃ The corresponding forgings.

P235GH steel for boiler, 09CuPCrNi-A weather resistant steel is origined in China. Its equivalent grades are JIS SPA-H, BS WR50A, Corten steel, etc. The Cu, P, Cr, Ni are important elements that gave 09CuPCrNi-A weather resistant steel its weathering ability. The Cu content of 09CuPCrNi-A steel is 0.25–0.50, P content is 0.060-0.12, Cr content is 0.30-1.25, Ni content is 0.12-0.65. For 09CuPCrNi-A steel coil ≤ 4mm, the min. yield strength is 310Mpa, min. tensile strength 440Mpa. For 09CuPCrNi-A steel sheets >4mm, the min. yield strength is 345Mpa, min. tensile strength 480Mpa.

After quenching and tempering, 40Cr alloy steel plate and p235gh steel for boiler sheet have good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel p235gh steel for boiler is good. It can be hardened to Ф28 ～ 60mm during water quenching and Ф15 ～ 40mm during oil quenching. In addition to quenching and tempering, this steel is also suitable for cyanidation and induction hardening. The cutting performance is better. When the hardness is HB174 ～ 229, the relative cutting workability is 60%. 40Cr alloy steel is suitable for making medium-sized plastic molds.
