IS 11169 (Part 1) 38Cr2 vs BS 970 (Part 1) 530A36

Close Alternative — 76.3% match based on chemical composition and mechanical property overlap.

IS 11169 (Part 1) 38Cr2 (IS 11169 (Part 1):2022) and BS 970 (Part 1) 530A36 (BS 970 (Part 1):1983) are both steel grades. Both fall under the Alloy Steel category. IS 11169 (Part 1) 38Cr2 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) 530A36 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) 38Cr2 is defined under Bureau of Indian Standards (IS), originating from India, while BS 970 (Part 1) 530A36 is defined under British Standards (BS), originating from United Kingdom.

As per chemical composition, IS 11169 (Part 1) 38Cr2 vs BS 970 (Part 1) 530A36 is a 76.3% 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 76.3%.
