Close Alternative — 76% match
based on chemical composition and mechanical property overlap.
BS 970 (Part 1) 304S11 (BS 970 (Part 1):1983) and EN 10088-1 1.4301 (EN 10088-1:2014) are both steel grades.
Both fall under the Stainless Steel category.
BS 970 (Part 1) 304S11 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 EN 10088-1 1.4301 is commonly used for food equipment, chemical vessels, architectural, kitchenware.
BS 970 (Part 1) 304S11 is defined under British Standards (BS), originating from United Kingdom, while EN 10088-1 1.4301 is defined under European Standard (EN), originating from Europe.
As per chemical composition, BS 970 (Part 1) 304S11 vs EN 10088-1 1.4301 is a 76% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a close alternative overall at 76%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
