IS 11169 (Part 1) 45C8 vs BS 970 EN36B

Related Material — 65% match based on chemical composition and mechanical property overlap.

IS 11169 (Part 1) 45C8 (IS 11169 (Part 1):2022) and BS 970 EN36B (BS 970:1955) are both steel grades. IS 11169 (Part 1) 45C8 is classified under Carbon Steel, while BS 970 EN36B is classified under Alloy Steel — a different category, which is worth noting alongside the chemistry match below. IS 11169 (Part 1) 45C8 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 EN36B is commonly used for case hardened gears and heavily loaded components. IS 11169 (Part 1) 45C8 is defined under Bureau of Indian Standards (IS), originating from India, while BS 970 EN36B is defined under British Standards (BS), originating from United Kingdom.

As per chemical composition, IS 11169 (Part 1) 45C8 vs BS 970 EN36B is a 65% 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 65%.
