The quality inspection department is responsible for the inspection management of raw materials and finished products, and the quality inspection and acceptance of products and raw materials. Strictly abide by the company's management system, conscientiously exercise the management power given by the company, and put an end to all ultra vires; be responsible for the inspection of all kinds of raw materials entering the company, and put forward quality problems and handling opinions.
Steel materials a633 grc can be classified not only by chemical composition, main quality grade, main performance or use characteristics, but also by habit into carbon steel and alloy steel. Carbon structural steel is easy to smelt, has good processability, low price and large output, and can meet the requirements of common parts of general engineering structure in performance. Carbon structural steel a633 grc is usually rolled into steel plates and various sections, which are used for mechanical parts such as factory buildings and bridges.
20Mn2 steel has medium strength, and the properties of 20Mn2 steel and 20Cr steel are similar. The impact toughness and weldability of 20Mn2 steel at low temperature are better than those of 20Cr steel. The plasticity and machinability of 20Mn2 steel are high during cold deformation. The hardenability of 20Mn2 steel is higher than that of corresponding carbon steel, a633 grc. Chemical composition of 20Mn2 steel: C: 0.17-0.24, Si: 0.17-0.37, Mn: 1.40-1.80. Mechanical properties of 20Mn2 steel: tensile strength ≥ 785 MPa, yield strength ≥ 590 MPa, elongation after fracture ≥ 10%, section expansion rate ≥ 40%, impact absorbed energy ≥ 47J.
NM400 alloy steel plate is a kind of wear-resistant steel plate. NM—The first letter of the Chinese pinyin 400 of the characters “resistant” and “grind” for wear resistance is the HB value of the Brinell hardness value. NM400 alloy plate is widely used in engineering machinery, mining machinery, coal mining machinery, environmental protection machinery, metallurgical machinery and other product parts. Excavator, loader, bulldozer bucket plate, blade, side blade, blade.
