DIN 17210 15Cr3 vs BS 970 (Part 1) 523H15

Close Alternative — 83.2% match based on chemical composition and mechanical property overlap.

DIN 17210 15Cr3 (DIN 17210:1986) and BS 970 (Part 1) 523H15 (BS 970 (Part 1):1983) are both steel grades. Both fall under the Alloy Steel category. DIN 17210 15Cr3 is typically used for low-alloy chromium case-hardening (carburizing) steel; gears, shafts, pins, and machine components requiring a hard wear-resistant carburized surface with a tough core, while BS 970 (Part 1) 523H15 is commonly used for case hardening steel supplied to specified hardenability limits (end quench test, table 10).. DIN 17210 15Cr3 is defined under Deutsches Institut fur Normung (DIN), originating from Germany, while BS 970 (Part 1) 523H15 is defined under British Standards (BS), originating from United Kingdom.

As per chemical composition, DIN 17210 15Cr3 vs BS 970 (Part 1) 523H15 is a 83.2% 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 83.2%.
