Strong Match — 89.3% match
based on chemical composition and mechanical property overlap.
IS 11169 (Part 1) 20C4GC (IS 11169 (Part 1):2022) and SAE J403 1020 (SAE J403:2009) are both steel grades.
Both fall under the Carbon Steel category.
IS 11169 (Part 1) 20C4GC 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 SAE J403 1020 is commonly used for chemistry-only grade; product scope as listed in the composition notes.
IS 11169 (Part 1) 20C4GC is defined under Bureau of Indian Standards (IS), originating from India, while SAE J403 1020 is defined under SAE International, originating from United States.
As per chemical composition, IS 11169 (Part 1) 20C4GC vs SAE J403 1020 is a 89.3% 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 89.3%.
Frequently Compared With IS 11169 (Part 1) 20C4GC:
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
