Strong Match — 90.4% match
based on chemical composition and mechanical property overlap.
IS 5517 40C8 (IS 5517:1993) and SAE J403 1038 (SAE J403:2009) are both steel grades.
Both fall under the Carbon Steel category.
IS 5517 40C8 is typically used for crankshafts, couplings, bolts, spindles, axles, gears, while SAE J403 1038 is commonly used for chemistry-only grade; product scope as listed in the composition notes.
IS 5517 40C8 is defined under Bureau of Indian Standards (IS), originating from India, while SAE J403 1038 is defined under SAE International, originating from United States.
As per chemical composition, IS 5517 40C8 vs SAE J403 1038 is a 90.4% 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 90.4%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
Chemistry-only grade; product scope as listed in the composition notes
Key Differences
IS 5517 40C8 specifies Si which is not specified for SAE J403 1038.
Can IS 5517 40C8 Be Substituted With SAE J403 1038?
