Duplex Steel S31803 Reducer Pipe Fittings resists chloride environments and sulphide stress corrosion. Meanwhile, these Duplex Steel S32205 Cross Pipe Fittings are also being offered in different sizes and shapes to our customers. Duplex Steel S31803 Bend Butt Weld Pipe Fittings will often perform well in environments which cause premature failure of austenitic grades.
Although Duplex Steel S32205 Stub End Butt Weld Pipe Fittings has good high temperature oxidation resistance, this grade – like other duplex stainless steels – suffers from embrittlement if held for even short times at temperatures above 300 Degree C. If embrittled, Duplex S31803 End Pipe Cap can only be rectified by a full solution annealing treatment. Duplex S32205 Dish Cap Pipe Fittings are almost never used above 300 Degree C.
