IS 11169 (Part 1) 23Cr1BT vs BS 970 (Part 1) 527H17

Related Material — 66.2% match based on chemical composition and mechanical property overlap.

IS 11169 (Part 1) 23Cr1BT (IS 11169 (Part 1):2022) and BS 970 (Part 1) 527H17 (BS 970 (Part 1):1983) are both steel grades. Both fall under the Alloy Steel category. IS 11169 (Part 1) 23Cr1BT 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) 527H17 is commonly used for case hardening steel supplied to specified hardenability limits (end quench test, table 10).. IS 11169 (Part 1) 23Cr1BT is defined under Bureau of Indian Standards (IS), originating from India, while BS 970 (Part 1) 527H17 is defined under British Standards (BS), originating from United Kingdom.

As per chemical composition, IS 11169 (Part 1) 23Cr1BT vs BS 970 (Part 1) 527H17 is a 66.2% 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 66.2%.
