EN 10083-3 33MnCrB5-2 vs IS 11169 (Part 1) 34C14BT
Close Alternative — 78.5% match
based on chemical composition and mechanical property overlap.
EN 10083-3 33MnCrB5-2 (EN 10083-3:2006) and IS 11169 (Part 1) 34C14BT (IS 11169 (Part 1):2022) are both steel grades.
Both fall under the Alloy Steel category.
EN 10083-3 33MnCrB5-2 is typically used for quenched and tempered, flame or induction hardened machine parts (clause 1), while IS 11169 (Part 1) 34C14BT is commonly 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).
EN 10083-3 33MnCrB5-2 is defined under European Standard (EN), originating from Europe, while IS 11169 (Part 1) 34C14BT is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, EN 10083-3 33MnCrB5-2 vs IS 11169 (Part 1) 34C14BT is a 78.5% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a close alternative overall at 78.5%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
