IS 11169 (Part 1) 20C10BT (quenching and tempering) vs SAE J404 5120
Close Alternative — 70.5% match
based on chemical composition and mechanical property overlap.
IS 11169 (Part 1) 20C10BT (quenching and tempering) (IS 11169 (Part 1):2022) and SAE J404 5120 (SAE J404:2009) are both steel grades.
Both fall under the Alloy Steel category.
IS 11169 (Part 1) 20C10BT (quenching and tempering) 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 SAE J404 5120 is commonly used for case hardened gears, pins, shafts, cams, automotive transmission parts.
IS 11169 (Part 1) 20C10BT (quenching and tempering) is defined under Bureau of Indian Standards (IS), originating from India, while SAE J404 5120 is defined under SAE International, originating from United States.
As per chemical composition, IS 11169 (Part 1) 20C10BT (quenching and tempering) vs SAE J404 5120 is a 70.5% 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 70.5%.
Frequently Compared With IS 11169 (Part 1) 20C10BT (quenching and tempering):
