The HP345 steel grade belongs to the high-strength category specified in the GB6653 standard and is primarily used for manufacturing low-pressure welded steel gas cylinders for liquid chlorine, liquid ammonia, etc. The volume of these cylinders typically ranges from 40 to 1400 liters. Additionally, HP345 is also utilized in the production of liquefied petroleum gas cylinders and acetylene cylinders.
There are three main advantages of using GB6653 HP345 steel in the production of various welded gas cylinders:
High Strength: HP345 steel possesses high yield strength and tensile strength, meeting the material strength requirements for welded gas cylinders.
Good Toughness: Through process measures such as grain refinement, HP345 steel maintains good plasticity and toughness while achieving high strength, enhancing the safety performance of the gas cylinders.
Easy to Process: HP345 steel exhibits excellent stamping and forming properties as well as welding performance, making the manufacturing process more efficient and convenient.
