High temperature (creep temperature above) boiler steel plate, generally indicates low alloy heat-resistant steel acier S690QL equivalent, the commonly used are chrome molybdenum steel, chrome molybdenum vanadium steel, chrome molybdenum tungsten steel, etc. For example, 15CrMoG and 12Cr1MoVG boiler steel plate in GB713 and gr 22 and gr 91 boiler steel plate in ASME SA387/SA387M. High temperature boiler steel plate acier S690QL equivalent is mainly used to manufacture high temperature pressure parts such as high temperature header end cover, steam pipe plug plate, etc.

The yield point of the steel structure determines the stress that the structure can withstand without permanent deformation. The minimum yield point of typical carbon structural steel is 235MPa. The minimum yield point of typical low-alloy high-strength steel is 345MPa. Therefore, according to the proportional relationship of its yield point, the use of low-alloy high-strength steel allows the stress to be 1.4 times higher than that of carbon structural steel. Compared with acier S690QL equivalent, carbon structural steel, the use of low-alloy high-strength steel can reduce the size of structural parts and reduce weight.

Superior process production line advantage sdf: The company has focused on weathering steel acier S690QL equivalent, pressure vessel plate, oil tank plate, pipeline steel plates, and steel welded structures for many years, and has a strong factory scale; one of the domestic excellent weathering steel manufacturers, serving customers all over the world; using frequency conversion and microcomputer program control, the equipment is highly automated; Improve product efficiency and improve product quality.

acier S690QL equivalent, 15CrMo alloy steel is Chinese material. It is characterized by high Chrome and Molybdenum contents. The 15CrMo alloy steel chrome content is 0.80-1.10, and molybdenum content is 0.40-0.55. Besides, 15CrMo carbon content is 0.12-0.18, silicon content is 0.17-0.37, manganese content is 0.40-0.70. The heating temperatures for quenching and tempering of 15CrMo alloy steel are 900 and 650 centigrade respectively. The yield point of 15CrMo alloy steel is 295Mpa.
