Guide to Using the Stahlschlüssel (Key to Steel) PDF
What is a Stahlschlüssel?
- Definition: A Stahlschlüssel (German for “steel key” or “steel code”) is a table or index listing steel grades, chemical compositions, mechanical properties, and cross-references between national and international standards (e.g., DIN, EN, ISO, AISI/ASTM).
- Purpose: Helps engineers and buyers match required material properties to available steel designations and ensures correct material selection for strength, weldability, and corrosion resistance.
The Rise of the Stahlschlüssel PDF
While the physical "Key" remains a popular desk reference, the Stahlschlüssel PDF has become the preferred format for several reasons:
3. Cost-Effectiveness
Licensed PDF versions are often more affordable than the hardcover edition. Additionally, many universities, testing labs, and corporate libraries subscribe to site licenses, providing the PDF to entire teams. stahlschlussel pdf

Key Features of the Stahlschlüssel PDF
A genuine, official Stahlschlüssel PDF contains: Guide to Using the Stahlschlüssel (Key to Steel)
- Approx. 25,000 material designations from over 250 standards bodies and producers.
- Chemical composition tables (C, Si, Mn, P, S, Cr, Mo, Ni, V, etc.) for each grade.
- A cross-reference matrix – the famous "conversion tables" showing direct equivalents.
- Appendices on heat treatment, hardenability, and comparison of structural steels.
- A brand name index – crucial for identifying proprietary alloys from commercial suppliers.
Case B: You have a material number (e.g., "1.4301")
- Go to Table 2.
- Search for
1.4301.
- You will find:
- Trade names: X5CrNi18-10, AISI 304, SUS 304
- Standard: EN 10088-3
- Composition: Cr 17.0-19.5%, Ni 8.0-10.5%
Scenario 3: Legacy Drawings
An old blueprint from 1985 calls for "BS 970 080M40." That standard is withdrawn. Search the PDF. The cross-reference shows it is replaced by EN 1.1183 (C40E). You can now order modern steel. Definition: A Stahlschlüssel (German for “steel key” or
