ASME SA588 Grade B Weathering Steel
ASME SA588 Grade B Weathering Steel
ASME SA588 Grade B Introduction:
ASME SA588 Grade B is high-resistance self-passivating alloy containing copper, chrome and phosphorus, characterised by a high resistance to corrosion and to tensile yield; these alloys are self-protective through the formation of a superficial coating that prevents the progressive extending of the corrosion process.
