High-strength hot-rolled steel plates produced to DIN 17155 (HI / HII) grades for pressure-vessel and gas-cylinder applications. Though DIN 17155 is an older German specification now largely superseded by EN standards, these traditional grades remain in demand for repair, legacy equipment and specific engineering requirements. We supply DIN 17155 HI/HII equivalent plates and sheets with consistent chemistry and workmanship to meet industrial customers' needs.
