Steel for gas cylinders and gas vessels are characterised by a minimum yield strength of 245 - 355Â MPa and by good weldability. The user of these steel grades must make sure that his calculation, design and processing methods are appropriate for the material. Steel for gas cylinders and gas vessels are used for manufacturing gas cylinders by welding cold-formed parts together and normalizing the finished cylinder.
The main grade of Steel for gas cylinders and gas vessels are :
