DIN 17210 20Mn5 vs BS 970 (Part 1) 045A10

Close Alternative — 79.6% match based on chemical composition and mechanical property overlap.

DIN 17210 20Mn5 (DIN 17210:1986) and BS 970 (Part 1) 045A10 (BS 970 (Part 1):1983) are both steel grades. Both fall under the Carbon Steel category. DIN 17210 20Mn5 is typically used for unalloyed manganese carbon steel for quenching and tempering; machine components requiring moderate strength and hardenability, while BS 970 (Part 1) 045A10 is commonly used for case hardening steel for mechanical and allied engineering purposes (table 11 mechanical properties).. DIN 17210 20Mn5 is defined under Deutsches Institut fur Normung (DIN), originating from Germany, while BS 970 (Part 1) 045A10 is defined under British Standards (BS), originating from United Kingdom.

As per chemical composition, DIN 17210 20Mn5 vs BS 970 (Part 1) 045A10 is a 79.6% match. Mechanical property data is not available for both grades, so this factor could not be scored. Combined, this makes them a close alternative overall at 79.6%.
