Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
IS 11169 (Part 1) 40C15BT (IS 11169 (Part 1):2022) and UNI 11234 100Cr6 (UNI 11234:2007) are both steel grades.
Both fall under the Alloy Steel category.
IS 11169 (Part 1) 40C15BT 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 UNI 11234 100Cr6 is commonly used for ball bearings,roller bearings,needle bearings,dies,punches,gauges,wear resistant components.
IS 11169 (Part 1) 40C15BT is defined under Bureau of Indian Standards (IS), originating from India, while UNI 11234 100Cr6 is defined under Ente Nazionale Italiano di Unificazione (UNI), originating from Italy.
As per chemical composition, IS 11169 (Part 1) 40C15BT vs UNI 11234 100Cr6 is a 52.8% 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) 40C15BT:
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
