BS 970 (Part 3) 430S17 vs EN 10088-1 1.4401

Minimal Match — 35% match based on chemical composition and mechanical property overlap.

BS 970 (Part 3) 430S17 (BS 970 (Part 3):1991) and EN 10088-1 1.4401 (EN 10088-1:2014) are both steel grades. Both fall under the Stainless Steel category. BS 970 (Part 3) 430S17 is typically used for bright cold finished bars (cold drawn, turned or precision ground) for general engineering purposes, in straight lengths; ferritic stainless steel (table 17), while EN 10088-1 1.4401 is commonly used for marine, chemical processing, pharmaceutical equipment. BS 970 (Part 3) 430S17 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 3) 430S17 vs EN 10088-1 1.4401 is a 64.7% 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%.
