ASME SA105 vs BS 970 (Part 1) 060A32

Minimal Match — 35% match based on chemical composition and mechanical property overlap.

ASME SA105 (ASME BPVC.II.A-2025 SA-105/SA-105M) and BS 970 (Part 1) 060A32 (BS 970 (Part 1):1983) 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 BS 970 (Part 1) 060A32 is commonly used for through hardening steel for mechanical and allied engineering purposes; supplied in the hardened and tempered conditions of table 6.. BS 970 (Part 1) 060A32 is defined under British Standards (BS) (United Kingdom).

As per chemical composition, ASME SA105 vs BS 970 (Part 1) 060A32 is a 81% match. Mechanical property data is not available for both grades, so this factor could not be scored. Combined, this makes them a minimal match overall at 35%.
