ASTM A182 F51 is a duplex stainless steel that offers a high resistance to general , pitting, stress and crevice corrosion, as well as a high mechanical strength and good weldability. As a result, this is a highly suitable material for applications dealing with environments containing chlorides and and hydrogen sulphide.
