Strong Match — 92.4% match
based on chemical composition and mechanical property overlap.
JIS G4304 SUS304L (JIS G4304:2021) and BS 970 (Part 1) 304S11 (BS 970 (Part 1):1983) are both steel grades.
Both fall under the Stainless Steel category.
JIS G4304 SUS304L is typically used for hot-rolled stainless steel plates and strips, while BS 970 (Part 1) 304S11 is commonly used for austenitic stainless and heat resisting steel for mechanical and allied engineering purposes (table 14, with table 15 for the cold drawn condition)..
JIS G4304 SUS304L is defined under Japanese Industrial Standards (JIS), originating from Japan, while BS 970 (Part 1) 304S11 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, JIS G4304 SUS304L vs BS 970 (Part 1) 304S11 is a 92.4% 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 92.4%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
