IS 11169 (Part 1) 41Cr4S3 vs BS 970 (Part 3) 530M40

Strong Match — 89.8% match based on chemical composition and mechanical property overlap.

IS 11169 (Part 1) 41Cr4S3 (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) 41Cr4S3 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) 41Cr4S3 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) 41Cr4S3 vs BS 970 (Part 3) 530M40 is a 89.8% 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 89.8%.
