EN 10088-2 X6CrNiMoNb17-12-2 vs BS 970 (Part 3) 316S31
Strong Match — 92.3% match
based on chemical composition and mechanical property overlap.
EN 10088-2 X6CrNiMoNb17-12-2 (EN 10088-2:2014) and BS 970 (Part 3) 316S31 (BS 970 (Part 3):1991) are both steel grades.
Both fall under the Stainless Steel category.
EN 10088-2 X6CrNiMoNb17-12-2 is typically used for general purposes, hot or cold rolled sheet/plate and strip, while BS 970 (Part 3) 316S31 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 X6CrNiMoNb17-12-2 is defined under European Standard (EN), originating from Europe, while BS 970 (Part 3) 316S31 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, EN 10088-2 X6CrNiMoNb17-12-2 vs BS 970 (Part 3) 316S31 is a 92.3% 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 92.3%.
