Close Alternative — 75.9% match
based on chemical composition and mechanical property overlap.
IS 4432 11C10S25 (IS 4432:1988) and SAE J403 1126 (SAE J403:2009) are both steel grades.
Both fall under the Free Machining Steel category.
IS 4432 11C10S25 is typically used for forgings and fabrication of case-hardened machine or automobile parts, while SAE J403 1126 is commonly used for chemistry-only grade; product scope as listed in the composition notes.
IS 4432 11C10S25 is defined under Bureau of Indian Standards (IS), originating from India, while SAE J403 1126 is defined under SAE International, originating from United States.
As per chemical composition, IS 4432 11C10S25 vs SAE J403 1126 is a 75.9% 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 75.9%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
