Stainless Steel 317 Tee Butt Weld Pipe Fittings will often perform well in environments which cause premature failure of austenitic grades. Stainless Steel 317 Cross Butt Weld Pipe Fittings has better resistance to sea water than grade 316. Although stainless steel has good high temperature oxidation resistance, Stainless Steel 317 Bend Butt Weld Pipe Fittings suffer from embrittlement if held for even short times at temperatures above 270 Degree C. If embrittled, Stainless Steel 317 Stub End can only be rectified by a full solution annealing treatment.
Because of its high strength, Stainless Steel 317 End Cap performs well in abrasion/corrosion conditions. A PRE guaranteed to be at least 40 indicates that Stainless Steel 317 Dish Cap Butt Weld Pipe Fittings has good pitting and crevice corrosion resistance to warm sea water and other high chloride environments.
