IS 11169 (Part 1) 20C10BT (quenching and tempering) vs BS 970 (Part 1) 590H17

Related Material — 67.7% match based on chemical composition and mechanical property overlap.

IS 11169 (Part 1) 20C10BT (quenching and tempering) (IS 11169 (Part 1):2022) and BS 970 (Part 1) 590H17 (BS 970 (Part 1):1983) are both steel grades. Both fall under the Alloy Steel category. IS 11169 (Part 1) 20C10BT (quenching and tempering) 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) 590H17 is commonly used for case hardening steel supplied to specified hardenability limits (end quench test, table 10).. IS 11169 (Part 1) 20C10BT (quenching and tempering) is defined under Bureau of Indian Standards (IS), originating from India, while BS 970 (Part 1) 590H17 is defined under British Standards (BS), originating from United Kingdom.

As per chemical composition, IS 11169 (Part 1) 20C10BT (quenching and tempering) vs BS 970 (Part 1) 590H17 is a 67.7% 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 67.7%.
