DIN 17204 36Mn5 vs BS 970 (Part 3) 070M55

Close Alternative — 83.1% match based on chemical composition and mechanical property overlap.

DIN 17204 36Mn5 (DIN 17204:1990-11) and BS 970 (Part 3) 070M55 (BS 970 (Part 3):1991) are both steel grades. Both fall under the Carbon Steel category. DIN 17204 36Mn5 is typically used for unalloyed manganese carbon steel for quenching and tempering, higher manganese content than 28mn6; shafts and machine components requiring higher hardenability and strength, while BS 970 (Part 3) 070M55 is commonly used for used for springs, blades, wear plates, hand tools, shafts, and cutting components.. DIN 17204 36Mn5 is defined under Deutsches Institut fur Normung (DIN), originating from Germany, while BS 970 (Part 3) 070M55 is defined under British Standards (BS), originating from United Kingdom.

As per chemical composition, DIN 17204 36Mn5 vs BS 970 (Part 3) 070M55 is a 83.1% 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 83.1%.
