The use of JIS SM490A plates

The seamless carbon steel pipe for ships (gb5213-85) is the seamless carbon steel pipe for the manufacture of class I pressure pipe system, class II pressure pipe system, boiler and Superheater of ships. JIS SM490A plates. The working temperature of carbon steel seamless pipe wall shall not exceed 450 ℃, and that of alloy steel seamless pipe wall shall exceed 450 ℃.

There is no weld on the outer surface of seamless steel pipe, which is the change from round steel progressive perforation to hollow round bar, with good compression resistance. According to different materials, the processed finished products JIS SM490A plates are applicable to a wide range of fields (for example: machine gearbox gears, gear wheel axles, cams, worms, piston pins, claw clutches, high-pressure pipes and various fasteners, high-grade carburized parts, such as gears, shafts, etc.) in the medium containing nitrogen hydrogen mixture for fluid transmission. It can improve the utilization of materials.

Blast furnace ironmaking is a traditional ironmaking method based on coke energy. It cooperates with converter steelmaking and is the main method of producing JIS SM490A plates steel at present. This dominance of blast furnace ironmaking is not expected to change for quite a long time. The essence of blast furnace ironmaking is the reduction of iron. Besides, coke is used as fuel and reducing agent. At high temperatures, iron ore or iron-containing raw materials are reduced from an oxide or mineral state to liquid pig iron.
