BS 970 (Part 3) 410S21 vs EN 10088-1 1.4006

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

BS 970 (Part 3) 410S21 (BS 970 (Part 3):1991) and EN 10088-1 1.4006 (EN 10088-1:2014) are both steel grades. Both fall under the Stainless Steel category. BS 970 (Part 3) 410S21 is typically used for bright cold finished bars (cold drawn, turned or precision ground) for general engineering purposes, in straight lengths; martensitic stainless steel (table 17), while EN 10088-1 1.4006 is commonly used for cutlery, turbine blades, fasteners, surgical instruments. BS 970 (Part 3) 410S21 is defined under British Standards (BS), originating from United Kingdom, while EN 10088-1 1.4006 is defined under European Standard (EN), originating from Europe.

As per chemical composition, BS 970 (Part 3) 410S21 vs EN 10088-1 1.4006 is a 78.7% 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%.
