Gas Cylinder Steel Plate Manufactured in China
HP295 is mainly used in the manufacture of liquefied gas cylinders, its chemical composition is stable, P, S content is low, pure steel, the internal organization, fine grain. Moderate strength, good plasticity, low yield ratio, yield platform is not obvious, vertical and horizontal performance of small differences, excellent cold stamping performance. Flat steel plate, with a small thickness of the plate. Low carbon equivalent, to adapt to automatic submerged arc welding, plasma welding and other welding process requirements.
Gas cylinder steel plate is used to manufacture the material which can be used repeatedly to manufacture liquefied petroleum gas cylinders with working temperature of 40-60 ℃, test pressure of 2.36 MPa, water volume of 23.5L, 35.5L, 118L. Delivery status: Hot-rolled steel In the hot-rolled state or controlled rolling state or heat treatment, the state of delivery, cold-rolled steel to the annealing state of delivery.
