A515 Grade 70 steel plate

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 260Mpa.

 

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..

 

Our Gangsteel is specialized in super thick steel plate, and we also have much experience about A HIC test. We could provide DNV, ABS, LR ,BV,CCS,GL,CE mark certificate in our super thickness to promise our steel quality. We sincerely invite our new and old customer come to visit our mill for our long steel business.
