1.1120 (DIN 17182 : 1992-05) GS-20 Mn 5 1.1120 DIN 17182 : 1992-05 DIN 17182 : 1992-05 replaced by DIN EN 10213-1/-3 : 1996-01 and DIN EN 10293 : 2005-06 Replaced Germany 1.1.1 ≤ 300 1)
1) Remark: In comparison to the unalloyed cast steel grades according to DIN 1681, the materials of this group show distinctly higher values of the notch impact energy. As a result of their low carbon content (0.23 per cent maximum), they are well suitable for welding. By liquid quenching and tempering, the connection of this material to the micro-alloyed fine-grain structural steels, which this cast steel grade is to be used together with in welded composite constructions, can be achieved for wall thicknesses of up to 40 mm.
