ASTM A515GR70 A515 Grade 70 steel plate
supplier
Gangsteel export welded boilers Grade ASTM A515GR70 A515 Grade 70 steel plates. We provide ASTM A515 GR.70 steel plate machined part and cutting service.
Keywords: ASTM A515GR70, ASTM A515GR.70, ASTM A515 GR.70, ASTM A515 Grade 70
Adopt Standard: A 515/A 515M-03
A515/A515M specification covers carbon-silicon steel plates primarily for intermediate and higher temperature service in welded boilers and other pressure vessels projects.
A515 Grade 70 steel tensile strength is 485Mpa to 620Mpa and the yield strength is min 270Mpa.
About the thickness of A515 Gr 70,
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, Gangsteel 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 70 heat treatment, if a515 grade 70 steel thick in 50mm or under this thickness, A515 Grade 70 normalized supplied in the as-rolled condition. If our customer requirement, we also could do normalized. If A515 Grade 70 thicknesses above 50mm, this plate shall be normalized..
