JIS G4303 SUS316 vs BS 970 (Part 3) 316S11

Close Alternative — 75% match based on chemical composition and mechanical property overlap.

JIS G4303 SUS316 (JIS G4303:2021) and BS 970 (Part 3) 316S11 (BS 970 (Part 3):1991) are both steel grades. Both fall under the Stainless Steel category. JIS G4303 SUS316 is typically used for marine applications, chemical processing, pharmaceutical equipment, while BS 970 (Part 3) 316S11 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 G4303 SUS316 is defined under Japanese Industrial Standards (JIS), originating from Japan, while BS 970 (Part 3) 316S11 is defined under British Standards (BS), originating from United Kingdom.

As per chemical composition, JIS G4303 SUS316 vs BS 970 (Part 3) 316S11 is a 75% match. Mechanical property data is not available for both grades, so this factor could not be scored. Combined, this makes them a close alternative overall at 75%.
