HP295 steel plate chemical composition and mechanical properties

HP295 steel plate is mainly used for manufacturing welding gas cylinder, which generally refers to the gas cylinder containing liquefied petroleum gas and dissolved acetylene gas. Therefore, the HP295 steel plate used to manufacture flasks needs higher strength index and toughness index. At the same time, HP295 steel plate has good cold forming performance.
