SA285 Grade B is a kind of common carbon steel, whose tensile is low or mid-low. There are three grades or levels material GR A/B/C in the standard ASME SA-285/SA-285M. Plates ordered to this specification SA285 Grade B are normally in the as-rolled condition. SA285 Grade B may be ordered from the supplier as normalized or stress relieved if so desired.The alloy SA285 Grade B is not heat treated for hardening.
SA285 Grade B is a kind of common carbon steel used for pressure vessel steel.SA285 Grade B is supplied throughout the oil gas and petrochemical industry.The material SA285 Grade B has good forming and welding characteristics under conventional methods.
