IS 11169 (Part 1) 16Ni8Cr6Mo2 vs BS 970 (Part 1) 822H17

Strong Match — 86.9% match based on chemical composition and mechanical property overlap.

IS 11169 (Part 1) 16Ni8Cr6Mo2 (IS 11169 (Part 1):1984) and BS 970 (Part 1) 822H17 (BS 970 (Part 1):1983) are both steel grades. Both fall under the Alloy Steel category. IS 11169 (Part 1) 16Ni8Cr6Mo2 is typically used for cold heading and cold extrusion; the standard covers wires, wire rods and bars of 2 to 100 mm diameter (clause 1.1), while BS 970 (Part 1) 822H17 is commonly used for case hardening steel supplied to specified hardenability limits (end quench test, table 10).. IS 11169 (Part 1) 16Ni8Cr6Mo2 is defined under Bureau of Indian Standards (IS), originating from India, while BS 970 (Part 1) 822H17 is defined under British Standards (BS), originating from United Kingdom.

As per chemical composition, IS 11169 (Part 1) 16Ni8Cr6Mo2 vs BS 970 (Part 1) 822H17 is a 86.9% 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 86.9%.
