DIN 17100 — General structural steels; quality specifications (withdrawn)
Scope
The German standard for general structural steels St33, St37-2, USt37-2, RSt37-2, St37-3, St44-2, St44-3, St52-3 and the machinery grades St50-2, St60-2, St70-2. Withdrawn in 1994 when EN 10025 was adopted, but the St37/St52 names remain in daily use worldwide. This page maps every DIN 17100 grade to its EN 10025-2 successor.
