Stahl Key to Steel is a well-known reference book (originally by Deutsche Edelstahlwerke / Stahlschlüssel) that lists thousands of steel grades from around the world, including their chemical compositions, mechanical properties, and international equivalents (DIN, AISI/SAE, EN, JIS, GB, etc.). The “Key to Steel” name refers to its tabular format that helps you cross-reference and identify unknown steel grades.
