IS 1570 (Part 2/Sec 1) 10C4 vs BS 970 (Part 1) 040A12

Strong Match — 92.4% match based on chemical composition and mechanical property overlap.

IS 1570 (Part 2/Sec 1) 10C4 (IS 1570 (Part 2/Sec 1):1979) and BS 970 (Part 1) 040A12 (BS 970 (Part 1):1991) are both steel grades. Both fall under the Carbon Steel category. IS 1570 (Part 2/Sec 1) 10C4 is typically used for wire for wood screws, welding electrode core wire and case hardened parts (the standard links this grade to is 1812, is 2879, is 4432), while BS 970 (Part 1) 040A12 is commonly used for as-rolled, or as-rolled and softened, steel (section two). IS 1570 (Part 2/Sec 1) 10C4 is defined under Bureau of Indian Standards (IS), originating from India, while BS 970 (Part 1) 040A12 is defined under British Standards (BS), originating from United Kingdom.

As per chemical composition, IS 1570 (Part 2/Sec 1) 10C4 vs BS 970 (Part 1) 040A12 is a 92.4% match. Mechanical property data is not available for both grades, so this factor could not be scored. Combined, this makes them a strong match overall at 92.4%.
