What is the difference between 4140, EN19, and 42CrMo4?
+
4140 (AISI/SAE), EN19 (BS 970), and 42CrMo4 (DIN/EN) are equivalent grades of chromium-molybdenum alloy steel with nearly identical chemical composition and mechanical properties. The difference is only in the standard system used — American (AISI), British (BS), or European (DIN). All are used for high-strength, high-toughness applications.
