Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
BS 970 (Part 1) 302S31 (BS 970 (Part 1):1983) and EN 10088-1 1.4401 (EN 10088-1:2014) are both steel grades.
Both fall under the Stainless Steel category.
BS 970 (Part 1) 302S31 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 1.4401 is commonly used for marine, chemical processing, pharmaceutical equipment.
BS 970 (Part 1) 302S31 is defined under British Standards (BS), originating from United Kingdom, while EN 10088-1 1.4401 is defined under European Standard (EN), originating from Europe.
As per chemical composition, BS 970 (Part 1) 302S31 vs EN 10088-1 1.4401 is a 63.1% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a minimal match overall at 35%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
