Strong Match — 100% match
based on chemical composition and mechanical property overlap.
ASME SA105 (ASME BPVC.II.A-2025 SA-105/SA-105M) and ASTM A105 (ASTM A105) 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 ASTM A105 is commonly used for flanges, fittings, valves, pressure piping components, forged pressure vessel parts.
ASTM A105 is defined under ASTM International (United States).
As per chemical composition, ASME SA105 vs ASTM A105 is a 100% match.
As per mechanical properties, the match is 100%.
Combined, this makes them a strong match overall at 100%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.

Can ASME SA105 Be Substituted With ASTM A105?
ASME SA105 and ASTM A105 overlap closely enough on chemistry and mechanical properties that ASTM A105 is often considered as a substitute for ASME SA105 in many applications. Always confirm the specific property range your application needs before substituting, and check with your supplier's mill certificate.
What is the difference between ASME SA105 and ASTM A105?
Both grades share a similar composition profile; see the specification table above for the exact chemistry and mechanical property values.
