19Mn6 steel

DIN 19MN6 steel plate, under EN 10120 standard, we can regard DIN 19MN6 steel plate for gas cylinders and gas vessels.
DIN 19MN6 steel plate are characterised by a good weldability. The user of DIN DIN 19MN6 steel plate must make sure that his calculation, design and processing methods are appropriate for the material. The steel grades of DIN 19MN6 steel plate are used for manufacturing gas cylinders by welding coldformed parts together and normalizing the inished cylinder.
