Strong Match — 86.2% match
based on chemical composition and mechanical property overlap.
ASTM A516/A516M Grade 55 (ASTM A516/A516M:2025) and SAE J403 1016 (SAE J403:2009) are both steel grades.
Both fall under the Carbon Steel category.
ASTM A516/A516M Grade 55 is typically used for welded pressure vessels where improved notch toughness is important, while SAE J403 1016 is commonly used for chemistry-only grade; product scope as listed in the composition notes.
ASTM A516/A516M Grade 55 is defined under ASTM International, originating from United States, while SAE J403 1016 is defined under SAE International, originating from United States.
As per chemical composition, ASTM A516/A516M Grade 55 vs SAE J403 1016 is a 86.2% 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 86.2%.
