Close Alternative — 82.2% match
based on chemical composition and mechanical property overlap.
EN 10088-1 1.4401 (EN 10088-1:2014) and BS 970 (Part 3) 316S11 (BS 970 (Part 3):1991) are both steel grades.
Both fall under the Stainless Steel category.
EN 10088-1 1.4401 is typically used for marine, chemical processing, pharmaceutical equipment, while BS 970 (Part 3) 316S11 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 1.4401 is defined under European Standard (EN), originating from Europe, while BS 970 (Part 3) 316S11 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, EN 10088-1 1.4401 vs BS 970 (Part 3) 316S11 is a 82.2% 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 82.2%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
