EN 10088-2 X6CrNiNb18-10 vs BS 970 (Part 3) 347S31

Strong Match — 93.3% match based on chemical composition and mechanical property overlap.

EN 10088-2 X6CrNiNb18-10 (EN 10088-2:2014) and BS 970 (Part 3) 347S31 (BS 970 (Part 3):1991) are both steel grades. Both fall under the Stainless Steel category. EN 10088-2 X6CrNiNb18-10 is typically used for general purposes, hot or cold rolled sheet/plate and strip, while BS 970 (Part 3) 347S31 is commonly 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). EN 10088-2 X6CrNiNb18-10 is defined under European Standard (EN), originating from Europe, while BS 970 (Part 3) 347S31 is defined under British Standards (BS), originating from United Kingdom.

As per chemical composition, EN 10088-2 X6CrNiNb18-10 vs BS 970 (Part 3) 347S31 is a 93.3% match. Mechanical property data is not available for both grades, so this factor could not be scored. Combined, this makes them a strong match overall at 93.3%.
