ASTM A514 vs BS 970 (Part 3) 805M17

Close Alternative — 73.4% match based on chemical composition and mechanical property overlap.

ASTM A514 (ASTM A514) and BS 970 (Part 3) 805M17 (BS 970 (Part 3):1991) are both steel grades. Both fall under the Alloy Steel category. ASTM A514 is typically used for used for cranes, mining equipment, pressure vessels, bridges, heavy trucks, and structural fabrication., while BS 970 (Part 3) 805M17 is commonly used for bright cold finished bars (cold drawn, turned or precision ground) for general engineering purposes, in straight lengths; alloy case hardening steel (table 15). ASTM A514 is defined under ASTM International, originating from United States, while BS 970 (Part 3) 805M17 is defined under British Standards (BS), originating from United Kingdom.

As per chemical composition, ASTM A514 vs BS 970 (Part 3) 805M17 is a 73.4% 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 73.4%.
