Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
BS 970 (Part 3) 303S31 (BS 970 (Part 3):1991) and EN 10088-1 1.4845 (EN 10088-1:2014) are both steel grades.
Both fall under the Stainless Steel category.
BS 970 (Part 3) 303S31 is typically 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), while EN 10088-1 1.4845 is commonly used for furnace parts, heat exchangers, kiln components.
BS 970 (Part 3) 303S31 is defined under British Standards (BS), originating from United Kingdom, while EN 10088-1 1.4845 is defined under European Standard (EN), originating from Europe.
As per chemical composition, BS 970 (Part 3) 303S31 vs EN 10088-1 1.4845 is a 64.5% 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.
