The Deutsches Institut für Normung (DIN) standards define high-quality steel specifications used across European engineering and manufacturing. These German-engineered standards ensure precision, reliability, and interoperability in industrial applications worldwide.
Below are some of the most widely used DIN steel grades, with links to their detailed chemical compositions and properties:
Common Structural & Engineering Steels
- DIN 1.0301 (St37) – General structural steel for construction and machinery
- DIN 1.0402 (C22) – Low carbon steel for forged parts and machinery
- DIN 1.0503 (C45) – Medium carbon steel for high-strength components
- DIN 1.7218 (25CrMo4) – Chromium-molybdenum alloy for high-stress parts
Popular Stainless Steels
- DIN 1.4301 (X5CrNi18-10) – 304 equivalent austenitic stainless steel
- DIN 1.4401 (X5CrNiMo17-12-2) – 316 equivalent molybdenum stainless
- DIN 1.4016 (X6Cr17) – Ferritic stainless for automotive applications
Tool Steels
- DIN 1.1274 (C60W) – High-carbon tool steel
- DIN 1.2344 (X40CrMoV5-1) – Hot work tool steel for dies and molds
- DIN 1.2842 (90MnCrV8) – Cold work tool steel for cutting tools
Key Applications of DIN Standard Steels
These grades are essential for:
- Automotive: Chassis components, engine parts (e.g., 25CrMo4)
- Industrial Machinery: Gears, shafts (e.g., C45)
- Construction: Structural supports, fasteners (e.g., St37)
- Tooling: Molds, cutting implements (e.g., X40CrMoV5-1)
