Close Alternative — 72.7% match
based on chemical composition and mechanical property overlap.
ASME SA105 (ASME BPVC.II.A-2025 SA-105/SA-105M) and ASTM A36 (ASTM A36) 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 A36 is commonly used for structural fabrication, bridges, buildings, machinery parts, flanges.
ASTM A36 is defined under ASTM International (United States).
As per chemical composition, ASME SA105 vs ASTM A36 is a 92.4% match.
As per mechanical properties, the match is 33.3%.
Combined, this makes them a close alternative overall at 72.7%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
ASME SA105 and ASTM A36 are a close alternative rather than a direct substitute. Some properties overlap well, but check the specific chemistry and mechanical rows above against your application's requirements before treating them as interchangeable.
What is the difference between ASME SA105 and ASTM A36?
Both grades share a similar composition profile; see the specification table above for the exact chemistry and mechanical property values.
Can ASME SA105 be substituted with ASTM A36?
ASME SA105 and ASTM A36 are a close alternative rather than a direct substitute. Some properties overlap well, but check the specific chemistry and mechanical rows above against your application's requirements before treating them as interchangeable.
