SAE J403 1002 vs ASME SA105

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

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

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