BS 970 (Part 3) 316S11 vs ASTM A959 .-

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

BS 970 (Part 3) 316S11 (BS 970 (Part 3):1991) and ASTM A959 .- (ASTM A959:2011) are both steel grades. Both fall under the Stainless Steel category. BS 970 (Part 3) 316S11 is typically 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), while ASTM A959 .- is commonly used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1). BS 970 (Part 3) 316S11 is defined under British Standards (BS), originating from United Kingdom, while ASTM A959 .- is defined under ASTM International, originating from United States.

As per chemical composition, BS 970 (Part 3) 316S11 vs ASTM A959 .- is a 65.3% 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%.
