Close Alternative — 83.6% match
based on chemical composition and mechanical property overlap.
IS 11169 (Part 1) 40Cr4Mo2 (IS 11169 (Part 1):2022) and GOST 4543 35XM (GOST 4543-2016) are both steel grades.
Both fall under the Alloy Steel category.
IS 11169 (Part 1) 40Cr4Mo2 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 GOST 4543 35XM is commonly used for gears, shafts, connecting rods, turbine fasteners, forged parts, high-strength components.
IS 11169 (Part 1) 40Cr4Mo2 is defined under Bureau of Indian Standards (IS) (India).
As per chemical composition, IS 11169 (Part 1) 40Cr4Mo2 vs GOST 4543 35XM is a 83.6% 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 83.6%.
