ASTM A516 boiler steel plate pressure vessel steel sheet introduction:
ASTM A516 boiler steel plate pressure vessel steel sheet is carbon steel intended primarily for service in welded pressure vessels where improved notch toughness is important. According to different strength levels, ASTM A516 boiler steel plate pressure vessel steel sheets are available in four grades: A516 grade 55, A516 grade 60, A516 grade 65, and A516 grade 70.
ASTM A516 boiler steel plate pressure vessel steel sheet shall be killed and shall conform to fine austenitic grain size requirements. The maximum thickness of ASTM A516 boiler steel plate pressure vessel steel sheet is limited only by the capacity of its composition to meet the specified A516 steel mechanical property requirements.

ASTM A516 boiler steel plate pressure vessel steel sheet application:
ASTM A516 boiler steel plate pressure vessel steel sheet is fine grained structural steel for pressure vessels. ASTM A516 boiler steel plate pressure vessel steel sheet is characterised by good weldability and high resistance to brittle cracking. ASTM A516 boiler steel plate pressure vessel steel sheets are used for manufacturing vessels for pressurized gas (LPG, butane and propane tanks), parts for steam boilers, compressors, etc.
