Duplex Steel 2205 Fittings， ASTM A815 WP-S S31803 1.4462 Butt Weld 90 Deg 5D Elbow B16.9
ASTM A815 WPS31803 Duplex Steel Pipe Fittings can be welded or seamless. These duplex steel fittings are made up of a corrosion resistant， strong and high temperature capable duplex steel material. The welded fittings can range from 1/8” to 48” in nominal size and the seamless fittings range from 1/8” to 24”. ASTM A815 WPS31803 Duplex Stainless Steel Buttweld Fittings are the most common form of fittings. ASME A815 WP-S S31803 Duplex Steel Butt Weld Pipe Fittings contain a combination of austenitic and ferrite stainless steel which has excellent corrosion & oxidation resistance， high tensile strength and excellent mechanical properties.
