03Symbol Interpretation of DIN 17100 St37-2
The DIN 17100 designation encodes the steel family, the strength class and the quality group — a compact code that tells you exactly what you are buying.
St
St — Steel (Stahl)
The leading prefix identifies the material as general structural steel for engineering use.
37
37 — Strength Class
Nominal minimum tensile strength of approximately 370 N/mm² (≈37 kgf/mm² class).
2
2 — Quality Group
Quality class with controlled chemistry and defined impact requirements (vs. group 1 basic grade).
DIN
DIN 17100 — Standard
German standard for general structural steels, widely referenced in European engineering.
04Chemical Composition (Heat Analysis)
Controlled non-alloy chemistry ensures consistent weldability, formability and batch-to-batch stability per DIN 17100.
