Close Alternative — 76% match
based on chemical composition and mechanical property overlap.
EN 10088-1 1.4301 (EN 10088-1:2014) and BS 970 (Part 3) 304S11 (BS 970 (Part 3):1991) are both steel grades.
Both fall under the Stainless Steel category.
EN 10088-1 1.4301 is typically used for food equipment, chemical vessels, architectural, kitchenware, while BS 970 (Part 3) 304S11 is commonly 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).
EN 10088-1 1.4301 is defined under European Standard (EN), originating from Europe, while BS 970 (Part 3) 304S11 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, EN 10088-1 1.4301 vs BS 970 (Part 3) 304S11 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.
