Strong Match — 93.4% match
based on chemical composition and mechanical property overlap.
BS 970 (Part 3) 304S31 (BS 970 (Part 3):1991) and GB/T 3280 06Cr19Ni10 (GB/T 3280-2015) are both steel grades.
Both fall under the Stainless Steel category.
BS 970 (Part 3) 304S31 is typically used for bright cold finished bars (cold drawn, turned or precision ground) for general engineering purposes, in straight lengths; austenitic stainless and heat resisting steel (table 18), 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 3) 304S31 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 3) 304S31 vs GB/T 3280 06Cr19Ni10 is a 93.4% 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 93.4%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
