Strong Match — 86.9% match
based on chemical composition and mechanical property overlap.
JIS G4305 SUS403 (JIS G4305:2012) and BS 970 (Part 1) 403S17 (BS 970 (Part 1):1983) are both steel grades.
Both fall under the Stainless Steel category.
JIS G4305 SUS403 is typically used for cold-rolled stainless steel plates, sheet and strip, while BS 970 (Part 1) 403S17 is commonly used for stainless and heat resisting steel for mechanical and allied engineering purposes (table 13)..
JIS G4305 SUS403 is defined under Japanese Industrial Standards (JIS), originating from Japan, while BS 970 (Part 1) 403S17 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, JIS G4305 SUS403 vs BS 970 (Part 1) 403S17 is a 86.9% 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 86.9%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
