30CrMo Gas Cylinder Tube is a kind of alloy structural steel. Its quench-hardening ability is higher, no temper brittleness. This material demonstrates very low tendency for cold crack formation while maintaining excellent machinability and cold straining plasticity. These properties make 30CrMo ideally suited for manufacturing critical components including CNG/LPG/hydrogen storage tanks, firefighting breathing apparatus cylinders, medical oxygen cylinders, industrial gas cylinders, fuel cell vehicle hydrogen tanks, scuba diving tanks, as well as various aerospace and military applications.
