JIS G4304 SUS317J2 vs BS 970 (Part 3) 316S31

Related Material — 68.7% match based on chemical composition and mechanical property overlap.

JIS G4304 SUS317J2 (JIS G4304:2021) and BS 970 (Part 3) 316S31 (BS 970 (Part 3):1991) are both steel grades. Both fall under the Stainless Steel category. JIS G4304 SUS317J2 is typically used for hot-rolled stainless steel plates and strips, 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). JIS G4304 SUS317J2 is defined under Japanese Industrial Standards (JIS), originating from Japan, while BS 970 (Part 3) 316S31 is defined under British Standards (BS), originating from United Kingdom.

As per chemical composition, JIS G4304 SUS317J2 vs BS 970 (Part 3) 316S31 is a 68.7% match. Mechanical property data is not available for both grades, so this factor could not be scored. Combined, this makes them a related material overall at 68.7%.
