We have full ranges of gas cylinder steels, not only GB standard gas cylinder steel, but also JIG standard and EN standard materials. Such as SG255, SG295, HP265, P245NB, etc. The MOQ is 200 tons. For the gas cylinder steel coil, we can do A709 grade 50S bridge steel plate further processing in our processing center and provide you gas cylinder steel plates. And we can punch steel discs for your convenient use.
A709 grade 50S bridge steel plate, 45# steel is widely used in mechanical manufacturing, and its mechanical properties are very good. But 45# steel is a kind of medium carbon steel, the quenching property is not good, 45# steel can be hardened to HRC42 ~ 46. Therefore, if the surface hardness is required, and the superior mechanical properties of 45# steel are expected to be exerted, the surface of 45# steel is often carburized and quenched, so that the required surface hardness can be obtained.
Chemical composition of 65Mn steel: C 0.62-0.70, Si 0.17-0.37, Mn 0.90-1.20, Cr ≤ 0.25, Ni ≤ 0.30, Cu ≤ 0.25. 65Mn steel mechanical properties: tensile strength: ≥735 Mpa, yield strength: ≥430 Mpa, elongation after fracture: ≥9%, reduction of area: 30%, impact absorbed energy: no impact. A709 grade 50S bridge steel plate, 65Mn steel has high strength, high hardenability, less decarburization tendency, overheat sensitivity, easy to produce quenching cracks and temper brittleness. 65Mn steel is used for making various flat and round springs, leaf springs, spring rings, valve springs, steel wire cold coil springs, clutch springs of light trucks and cars.
SG255 gas cylinder A709 grade 50S bridge steel plate steel is widely used in petroleum, chemical industry, power station, boiler, etc, used to make the reactor, heat exchanger, separator.
