Our company was founded in 2000, which initially committed to providing high-quality steel A709 Gr 50 structural steel sheet products for China's rapid infrastructure construction. With the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel in the international market, we began to export A709 Gr 50 structural steel sheet steel to the international market, opening up the international steel market.
A709 Gr 50 structural steel sheet, JIS 3101 SS540 is high strength low alloy steel plate sheet, which is widely used in plants building, general mansions and all kinds of construction machinery, such as mines and various types of drilling rig used in construction, power shovel, electric wheel dump trucks, mining vehicles, excavators, loaders, bulldozers , various types of cranes, hydraulic support, coal mining machinery and equipment and other structures.
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 A709 Gr 50 structural steel sheet, carbon structural steel, the use of low-alloy high-strength steel can reduce the size of structural parts and reduce weight.
Composition characteristics of Q420 alloy steel plate: 1.Low carbon: Due to the high requirements for toughness, weldability and cold forming performance, its carbon content does not exceed 0.20%. 2. Add manganese-based alloy elements. 3. Add auxiliary elements such as niobium, titanium or vanadium, which is beneficial to obtain fine ferrite grains and improve the strength and toughness of the Q420 alloy steel, A709 Gr 50 structural steel sheet.
SS400 is a low carbon steel with no specified carbon content. According to its mechanical properties, it is similar to A709 Gr 50 structural steel sheet ASTM A36, which is widely used in engineering and industrial applications. The cost of JIS SS400 steel angle steel structure is low, and it has good performance in major projects. SS400 angle steel description:Item: SS400 angle steel.
