Adopt Standard: SA515/SA515M-03
SA515/SA515M specification covers carbon-silicon steel plates primarily for intermediate and higher temperature service in welded boilers and other pressure vessels projects.
SA515 Gr.70 steel tensile strength is 485Mpa to 620Mpa. the yield strength is min 270Mpa.
About the thickness of SA515 Gr.70, Gangsteel maximum thickness of plates is limited only by the capacity of the composition to meet the specified mechanical property requirements.
Now, at mill practice, Gangsteel normally limits the maximum thickness of plate are 300mm. the delivery station are UT test, normalized.
SA515 Gr.70 heat treatment, if SA515 Gr.70 steel thick in 50mm or under this thickness, SA515 Gr.70 normalized supplied in the as-rolled condition. If our customer requirement, we could do normalized too. If SA515 Gr.70 thicknesses are above 50mm, this plate is normalized..
