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 42CrMoS4 round bar for fastener further processing in our processing center and provide you gas cylinder steel plates. And we can punch steel discs for your convenient use.
42CrMoS4 round bar for fastener, Hot-rolled steel coils are made of steel billets, which are made into strip steel by the rough rolling mill and the finishing mill after heating. The hr steel strip from the rolling mill behind the finishing rolling is cooled to a set temperature by laminar flow, and then coiled into a steel coil by the coiler. The cooled steel coil will undergo different processes according to the different needs of users, and is processed into steel plates, flat coils and slit steel strip products.
S355J2G3 is low alloy high strength structural steel, and it is roughly equivalent to GB Q345D.S355J2G3 is a European standard steel with composition of C ≤ 0.20, Si ≤ 0.55, Mn ≤ 1.60, P ≤ 0.035, S ≤ 0.035. The meaning of J2G3 indicates that the delivery state of S355J2G3 steel is normalized, the impact energy at - 20 ℃ is 27J. G3 and G4 indicate the deoxidization mode. 42CrMoS4 round bar for fastener, S355J2G3 steel is semi killed steel, S355J2G4 steel is fully killed steel.
