Close Alternative — 74.2% match
based on chemical composition and mechanical property overlap.
IS 11169 (Part 1) 46Cr2 (IS 11169 (Part 1):2022) and BS 970 (Part 3) 530M40 (BS 970 (Part 3):1991) are both steel grades.
Both fall under the Alloy Steel category.
IS 11169 (Part 1) 46Cr2 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 3) 530M40 is commonly used for bright cold finished bars (cold drawn, turned or precision ground) for general engineering purposes, in straight lengths; alloy direct hardening steel (table 16).
IS 11169 (Part 1) 46Cr2 is defined under Bureau of Indian Standards (IS), originating from India, while BS 970 (Part 3) 530M40 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, IS 11169 (Part 1) 46Cr2 vs BS 970 (Part 3) 530M40 is a 74.2% 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 74.2%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
