Pressure Vessel Steel Home Page DIN 17155 HI | HII | 17Mn4 | 19Mn6 |
DIN 17155 HII is the German standard for pressure vessel steel. This standard is no longer active and has been superseded along with the old British Standard by EN 10028, the new Euro Norm standard. Our customers often search and make sales enquiries for this steel grade and as a consequence we have provided grade specification details on this website.
Please refer to the technical data below. Note that this information should be used for cross reference purposes – please refer to equivalent grades when making your enquiry for our pressure vessel grade steels.
