IS 4367 20C15 vs SAE J403 1524

Strong Match — 87.8% match based on chemical composition and mechanical property overlap.

IS 4367 20C15 (IS 4367:1991) and SAE J403 1524 (SAE J403:2009) are both steel grades. Both fall under the Carbon Steel category. IS 4367 20C15 is typically used for low-carbon case-hardening (carburizing) steel; used for lightly stressed components such as pins, bushes, and small shafts requiring a hard wear-resistant surface with a tough core, while SAE J403 1524 is commonly used for chemistry-only grade; product scope as listed in the composition notes. IS 4367 20C15 is defined under Bureau of Indian Standards (IS), originating from India, while SAE J403 1524 is defined under SAE International, originating from United States.

As per chemical composition, IS 4367 20C15 vs SAE J403 1524 is a 87.8% 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 87.8%.
