Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
IS 11169 (Part 1) 20C10BT (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) 20C10BT 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 NF A35-565 100C6 is commonly used for ball bearings, roller bearings, bearing races, rollers, precision tools, wear resistant parts.
IS 11169 (Part 1) 20C10BT 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) 20C10BT vs NF A35-565 100C6 is a 67.6% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a minimal match overall at 35%.
Frequently Compared With IS 11169 (Part 1) 20C10BT:
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
