IS 11169 (Part 1) 45C7S3 vs BS 970 (Part 1) 080H46
Strong Match — 85% match
based on chemical composition and mechanical property overlap.
IS 11169 (Part 1) 45C7S3 (IS 11169 (Part 1):2022) and BS 970 (Part 1) 080H46 (BS 970 (Part 1):1983) are both steel grades.
Both fall under the Carbon Steel category.
IS 11169 (Part 1) 45C7S3 is typically used for cold heading and cold extrusion of parts that are quenched and tempered; the standard covers bars, wire rods and wires of 2 to 100 mm (clause 1.1, annex c), while BS 970 (Part 1) 080H46 is commonly used for through hardening steel for mechanical and allied engineering purposes; supplied in the hardened and tempered conditions of table 6..
IS 11169 (Part 1) 45C7S3 is defined under Bureau of Indian Standards (IS), originating from India, while BS 970 (Part 1) 080H46 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, IS 11169 (Part 1) 45C7S3 vs BS 970 (Part 1) 080H46 is a 85% 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 85%.
Frequently Compared With IS 11169 (Part 1) 45C7S3:
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
