Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
IS 11169 (Part 1) 31Cr2Mo1BT (IS 11169 (Part 1):2022) and NF A35-565 100C6 are both steel grades.
Both fall under the Alloy Steel category.
IS 11169 (Part 1) 31Cr2Mo1BT 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 NF A35-565 100C6 is commonly used for ball bearings, roller bearings, bearing races, rollers, precision tools, wear resistant parts.
IS 11169 (Part 1) 31Cr2Mo1BT is defined under Bureau of Indian Standards (IS), originating from India, while NF A35-565 100C6 is defined under Association Francaise de Normalisation (NF), originating from France.
As per chemical composition, IS 11169 (Part 1) 31Cr2Mo1BT vs NF A35-565 100C6 is a 57.6% match.
As per mechanical properties, the match is 0%.
Combined, this makes them a minimal match overall at 35%.
Frequently Compared With IS 11169 (Part 1) 31Cr2Mo1BT:
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
