Strong Match — 100% match
based on chemical composition and mechanical property overlap.
ASTM A959 SS310 (ASTM A959:2011) and ASTM A276/A276M S31000 (ASTM A276/A276M:2017) are both steel grades.
Both fall under the Stainless Steel category.
ASTM A959 SS310 is typically used for furnace parts, heat exchangers, kiln components, while ASTM A276/A276M S31000 is commonly used for stainless steel bars and shapes (hot-finished or cold-finished).
ASTM A959 SS310 is defined under ASTM International, originating from United States, while ASTM A276/A276M S31000 is defined under ASTM International, originating from United States.
As per chemical composition, ASTM A959 SS310 vs ASTM A276/A276M S31000 is a 100% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
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.
