ISO Q235b A36 Wear Resistant Steel Plate Hot Rolled Ms SS400 3mm

  Q235B has a certain degree of elongation, strength, good toughness and castability, and is easy to stamp and weld. It is widely used in the manufacture of general mechanical parts. Mainly used for welding structural parts with higher quality requirements in construction and bridge engineering.

  The smelting of carbon steel is usually carried out in converters and open hearth furnaces. The converter generally smelts ordinary carbon steel, while the open hearth can smelt various high-quality steels. The oxygen top-blown converter steelmaking technology has developed rapidly, and there is a trend to replace open-hearth steelmaking. Inject the refined molten steel into a steel ingot mold to obtain various steel ingots. Steel ingots are processed into steel plates, steel strips, steel bars and various cross-sectional shapes after forging or rolling. Carbon steel is generally used directly in the hot rolled state. When used in the manufacture of tools and various machine parts, heat treatment is required according to the requirements of use; as for steel castings, most of them must be heat treated.
