ASTM A959 S41026 vs BS 970 (Part 3) 416S41

Close Alternative — 73.1% match based on chemical composition and mechanical property overlap.

ASTM A959 S41026 (ASTM A959:2011) and BS 970 (Part 3) 416S41 (BS 970 (Part 3):1991) are both steel grades. Both fall under the Stainless Steel category. ASTM A959 S41026 is typically used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1), while BS 970 (Part 3) 416S41 is commonly used for bright cold finished bars (cold drawn, turned or precision ground) for general engineering purposes, in straight lengths; martensitic stainless steel (table 17). ASTM A959 S41026 is defined under ASTM International, originating from United States, while BS 970 (Part 3) 416S41 is defined under British Standards (BS), originating from United Kingdom.

As per chemical composition, ASTM A959 S41026 vs BS 970 (Part 3) 416S41 is a 73.1% 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 73.1%.
