DIN 1654-2 C8C vs BS 970 (Part 1) 040A04

Minimal Match — 35% match based on chemical composition and mechanical property overlap.

DIN 1654-2 C8C (DIN 1654-2:1989-10) and BS 970 (Part 1) 040A04 (BS 970 (Part 1):1991) are both steel grades. Both fall under the Carbon Steel category. DIN 1654-2 C8C is typically used for wire drawing, cold heading, nails, while BS 970 (Part 1) 040A04 is commonly used for as-rolled, or as-rolled and softened, steel (section two). DIN 1654-2 C8C is defined under Deutsches Institut fur Normung (DIN), originating from Germany, while BS 970 (Part 1) 040A04 is defined under British Standards (BS), originating from United Kingdom.

As per chemical composition, DIN 1654-2 C8C vs BS 970 (Part 1) 040A04 is a 95.6% match. Mechanical property data is not available for both grades, so this factor could not be scored. Combined, this makes them a minimal match overall at 35%.
