Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
BS 970 (Part 1) 304S31 (BS 970 (Part 1):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 1) 304S31 is typically used for austenitic stainless and heat resisting steel (section five), while EN 10088-1 1.4845 is commonly used for furnace parts, heat exchangers, kiln components.
BS 970 (Part 1) 304S31 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 1) 304S31 vs EN 10088-1 1.4845 is a 68.9% match.
As per mechanical properties, the match is 33.3%.
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.
