Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
BS 970 (Part 1) 303S42 (BS 970 (Part 1):1983) and GB/T 3280 06Cr19Ni10 (GB/T 3280-2015) are both steel grades.
Both fall under the Stainless Steel category.
BS 970 (Part 1) 303S42 is typically used for austenitic stainless and heat resisting steel for mechanical and allied engineering purposes (table 14, with table 15 for the cold drawn condition)., while GB/T 3280 06Cr19Ni10 is commonly used for used for kitchen equipment, food processing machinery, chemical tanks, piping, architectural panels, and fasteners..
BS 970 (Part 1) 303S42 is defined under British Standards (BS), originating from United Kingdom, while GB/T 3280 06Cr19Ni10 is defined under Guobiao Standards (GB/T), originating from China.
As per chemical composition, BS 970 (Part 1) 303S42 vs GB/T 3280 06Cr19Ni10 is a 78.9% 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%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
