Related Material — 69.2% match
based on chemical composition and mechanical property overlap.
ASTM A240/A240M S21400 (ASTM A240/A240M:2025) and GB/T 3280 06Cr19Ni10 (GB/T 3280-2015) are both steel grades.
Both fall under the Stainless Steel category.
ASTM A240/A240M S21400 is typically used for pressure vessels and general applications (plate, sheet and strip), while GB/T 3280 06Cr19Ni10 is commonly used for used for kitchen equipment, food processing machinery, chemical tanks, piping, architectural panels, and fasteners..
ASTM A240/A240M S21400 is defined under ASTM International, originating from United States, while GB/T 3280 06Cr19Ni10 is defined under Guobiao Standards (GB/T), originating from China.
As per chemical composition, ASTM A240/A240M S21400 vs GB/T 3280 06Cr19Ni10 is a 69.2% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a related material overall at 69.2%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
