IS 1570 (Part 2/Sec 1) 70C6 vs BS 970 (Part 1) 040A04
Related Material — 69.9% match
based on chemical composition and mechanical property overlap.
IS 1570 (Part 2/Sec 1) 70C6 (IS 1570 (Part 2/Sec 1):1979) and BS 970 (Part 1) 040A04 (BS 970 (Part 1):1991) are both steel grades.
Both fall under the Carbon Steel category.
IS 1570 (Part 2/Sec 1) 70C6 is typically used for cold rolled strip for springs, spring washers and cold rolled medium and high carbon strip (the standard links this grade to is 2507, is 4072, is 7226), while BS 970 (Part 1) 040A04 is commonly used for as-rolled, or as-rolled and softened, steel (section two).
IS 1570 (Part 2/Sec 1) 70C6 is defined under Bureau of Indian Standards (IS), originating from India, while BS 970 (Part 1) 040A04 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, IS 1570 (Part 2/Sec 1) 70C6 vs BS 970 (Part 1) 040A04 is a 85.7% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a related material overall at 69.9%.
Frequently Compared With IS 1570 (Part 2/Sec 1) 70C6:
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
