ASTM A573 Grade 58(A573 Gr 58) sheet, Alloy steel plate can be used for machining machinery and equipment. The requirement of the equipment to the steel plate is very high, so the alloy steel plate is mostly used to manufacture the mechanical equipment. The alloy steel plate can also be used as raw materials for fastening hardware. Nuts and bolts are used in a complex environment, so there must be certain requirements for strength and high temperature resistance. Otherwise, if fracture occurs, it will lead to accidents and cause a series of irreparable consequences.
ASTM A573 Grade 58(A573 Gr 58) sheet, Hardened wear-resistant plates are gradually annealed at a temperature higher than 250℃ to lose their hardness, which greatly reduces the wear resistance. The welding process will also reduce the hardness near the weld; the wear layer of the bimetal wear plate is of high alloy composition, and there is a secondary hardening effect at a certain temperature, and it can generally work below 650℃.
Most common ASTM A573 Grade 58(A573 Gr 58) sheet steel plates are rolled by hot rolling or controlled rolling. Compared with the general hot rolling process, the advantages of controlled rolling are: the strength and low temperature toughness of steel plates are greatly improved by controlled rolling to refine grains. In addition, the controlled rolling process can give full play to the role of Microalloying Elements Nb, V and Ti, not only play a role of precipitation strengthening, but also refine the grains, and improve the toughness of the rolled ASTM A573 Grade 58(A573 Gr 58) sheet steel plates.
