ASME SA105 vs SAE J403 1002

Close Alternative — 83.4% match based on chemical composition and mechanical property overlap.

ASME SA105 (ASME BPVC.II.A-2025 SA-105/SA-105M) and SAE J403 1002 (SAE J403:2014) are both steel grades. Both fall under the Carbon Steel category. ASME SA105 is typically used for pressure vessel flanges, boiler fittings, valves, piping components requiring asme certification, while SAE J403 1002 is commonly used for chemistry-only grade; product scope as listed in the composition notes. SAE J403 1002 is defined under SAE International (United States).

As per chemical composition, ASME SA105 vs SAE J403 1002 is a 83.4% 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 83.4%.
