17Mn4 steel

DIN 17Mn4 steel are characterised by a good weldability. The user of DIN 17Mn4 steel must make sure that his calculation, design and processing methods are appropriate for the material. The DIN 17Mn4 steel of this series are used for manufacturing gas cylinders by welding cold-formed parts together and normalizing the inished cylinder.
