IS 11169 (Part 1) 20Mo5Cr2 vs BS 970 (Part 1) 708H20

Close Alternative — 71.1% match based on chemical composition and mechanical property overlap.

IS 11169 (Part 1) 20Mo5Cr2 (IS 11169 (Part 1):2022) and BS 970 (Part 1) 708H20 (BS 970 (Part 1):1983) are both steel grades. Both fall under the Alloy Steel category. IS 11169 (Part 1) 20Mo5Cr2 is typically used for cold heading and cold extrusion of parts that are case hardened; the standard covers bars, wire rods and wires of 2 to 100 mm (clause 1.1, annex b), while BS 970 (Part 1) 708H20 is commonly used for case hardening steel supplied to specified hardenability limits (end quench test, table 10).. IS 11169 (Part 1) 20Mo5Cr2 is defined under Bureau of Indian Standards (IS), originating from India, while BS 970 (Part 1) 708H20 is defined under British Standards (BS), originating from United Kingdom.

As per chemical composition, IS 11169 (Part 1) 20Mo5Cr2 vs BS 970 (Part 1) 708H20 is a 71.1% 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 71.1%.
