BS 970 (Part 3) 316S33 vs EN 10088-1 1.4401

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

BS 970 (Part 3) 316S33 (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) 316S33 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 1.4401 is commonly used for marine, chemical processing, pharmaceutical equipment. BS 970 (Part 3) 316S33 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) 316S33 vs EN 10088-1 1.4401 is a 74.8% 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%.
