A516 grade 65 boiler steel plate
A516 grade 65 steel plate is a kind of pressure vessel plates, and A516 grade 65 steel plate is used for moderate and lower- temperature service. The following is A516 grade 65 steel plate details for your reference.
ASTM A516 steel plates under 40mm in thickness is normally supplied in the as-rolled condition. The plates may be ordered normalized or stress relieved, or both. ASTM A516 grade 65 steel plates over 40mm in thickness shall be normalized.
A516 grade 65 boiler steel plate specification:
Thickness: 6MM to 300MM,
Width: 1500mm to 4050mm,
Length: 3000mm to 15000mm
