Strong Match — 95.3% match
based on chemical composition and mechanical property overlap.
BS 970 (Part 3) 403S17 (BS 970 (Part 3):1991) and JIS G4304 SUS410S (JIS G4304:2021) are both steel grades.
Both fall under the Stainless Steel category.
BS 970 (Part 3) 403S17 is typically used for bright cold finished bars (cold drawn, turned or precision ground) for general engineering purposes, in straight lengths; ferritic stainless steel (table 17), while JIS G4304 SUS410S is commonly used for hot-rolled stainless steel plates and strips.
BS 970 (Part 3) 403S17 is defined under British Standards (BS), originating from United Kingdom, while JIS G4304 SUS410S is defined under Japanese Industrial Standards (JIS), originating from Japan.
As per chemical composition, BS 970 (Part 3) 403S17 vs JIS G4304 SUS410S is a 95.3% 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 95.3%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
