EN 10213 Grade GX23CrMoV12-1 quenched and tempered (+QT)

EN 10213 Grade GX23CrMoV12-1 quenched and tempered (+QT) introduction

Material GX23CrMoV12-1 is equivalent to trademark G-X 22 CrMoV 12-1 acc. to DIN17245-87. It is due to its high creep and thermal strength (except at temperatures around 600 °C) applicated if fast temperature changes or even thermal shocks may occur. The well weldable material is used at room temperature and increased temperatures (up to approx. 600 °C) for turbine casings, valve boxes and steam collecting boxes as well as for reeling segments of wide strip lines.

Equivalent material: DIN G-X22CrMoV12-1, ISO GX23CrMoV12-1, DIN 1.4931, DIN GX23CrMoV12-1, EN 1.4931
