A515/A515M specification covers carbon-silicon steel plates primarily for intermediate and higher temperature service in welded boilers and other pressure vessels projects.

ASTM A515 Grade 55 is categorized as Carbon Steel. It is composed of (in weight percentage) 0.28% Carbon (C), 0.90% Manganese (Mn), 0.035% Phosphorus (P), 0.04% Sulfur (S), 0.15-0.30% Silicon (Si), and the base metal Iron (Fe). Another common designation of ASTM A515 Grade 55 carbon steel is UNS K02001.

A515 Grade 60 steel tensile strength is 415Mpa to 550Mpa and the yield strength is min 415Mpa. About the thickness of A515 Gr 60, Gangsteel maximum thickness of plates is limited only by the capacity of the composition to meet the specified mechanical property requirements.
Now, in our mill practice, Our company normally limits the maximum thickness of plate is 300mm. the delivery station is UT test, normalized and have to use the ingot to produce it.

A515 Grade 60 heat treatment, if a515 grade 60 steel thick in 50mm or under this thickness, A515 Grade 60 normalized supplied in the as-rolled condition. If our customer requirement, we also could do normalized. If A515 Grade 60 thicknesses above 50mm, this plate shall be normalized..

ASTM A515 Grade 70 is categorized as Carbon Steel. It is composed of (in weight percentage) 0.35% Carbon (C), 0.90% Manganese (Mn), 0.035% Phosphorus (P), 0.04% Sulfur (S), 0.15-0.30% Silicon (Si), and the base metal Iron (Fe). Another common designation of ASTM A515 Grade 70 carbon steel is UNS K03101.
