DIN 17100 St52 Steel

St52 steel (St52-3) is an unalloyed structural steel grade complies with DIN 17100: 1980, the designation has been discarded since 2004. According to German standard DIN 17100, St52 steel is divided into St52-3U (1.0553) and St52-3N (1.0570 material). St 52 material new designation is S355, St52-3 new name is S355J2 (1.0577), St52-3 U new designation is S355J0 (1.0553), and St52-3 N new name in EN 10025: 1993 is S355J2G3, DIN 17100 has been replaced by EN 10025-2: 2004.
