IS 11169 (Part 1) 17C10BT vs BS 970 (Part 1) 527M17

Close Alternative — 71.3% match based on chemical composition and mechanical property overlap.

IS 11169 (Part 1) 17C10BT (IS 11169 (Part 1):2022) and BS 970 (Part 1) 527M17 (BS 970 (Part 1):1983) are both steel grades. Both fall under the Alloy Steel category. IS 11169 (Part 1) 17C10BT 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) 527M17 is commonly used for case hardening steel for mechanical and allied engineering purposes (table 11 mechanical properties).. IS 11169 (Part 1) 17C10BT is defined under Bureau of Indian Standards (IS), originating from India, while BS 970 (Part 1) 527M17 is defined under British Standards (BS), originating from United Kingdom.

As per chemical composition, IS 11169 (Part 1) 17C10BT vs BS 970 (Part 1) 527M17 is a 71.3% 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 71.3%.
