GB/T6653 HP325 Welded Gas Cylinder steel plates and coils

HP325 steel size:
Thickness: 1.6mm-12mm
Width: 800mm-1630mm
Length: 3000mm-18000mm OR Coils

GB/T6653 HP325 gas cylinder steel coils/sheets/plates for welded gas cylinders usually have uniform thickness, smooth and clean surface, low carbon content etc. features.

With grain refinement, GB/T6653 HP325 gas cylinder steel coils/sheets/plates can maintain good plasticity, toughness and process ability at the same time with high strength. Those characteristics create necessary conditions for production and safe use of welded gas cylinders.
