ASTM A516/A516M Grade 65 vs BS 970 (Part 3) 080M15
Strong Match — 85.5% match
based on chemical composition and mechanical property overlap.
ASTM A516/A516M Grade 65 (ASTM A516/A516M:2025) and BS 970 (Part 3) 080M15 (BS 970 (Part 3):1991) are both steel grades.
Both fall under the Carbon Steel category.
ASTM A516/A516M Grade 65 is typically used for welded pressure vessels where improved notch toughness is important, while BS 970 (Part 3) 080M15 is commonly used for bright cold finished bars (cold drawn, turned or precision ground) for general engineering purposes, in straight lengths; carbon and carbon manganese steel (table 13).
ASTM A516/A516M Grade 65 is defined under ASTM International, originating from United States, while BS 970 (Part 3) 080M15 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, ASTM A516/A516M Grade 65 vs BS 970 (Part 3) 080M15 is a 85.5% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a strong match overall at 85.5%.
