Strong Match — 92.7% match
based on chemical composition and mechanical property overlap.
IS 11169 (Part 1) 20C10BT (IS 11169 (Part 1):2022) and EN 10083-3 20MnB5 (EN 10083-3:2006) 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 EN 10083-3 20MnB5 is commonly used for quenched and tempered, flame or induction hardened machine parts (clause 1).
IS 11169 (Part 1) 20C10BT is defined under Bureau of Indian Standards (IS), originating from India, while EN 10083-3 20MnB5 is defined under European Standard (EN), originating from Europe.
As per chemical composition, IS 11169 (Part 1) 20C10BT vs EN 10083-3 20MnB5 is a 92.7% 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 92.7%.
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.
