Tiptop offers a variety of duplex stainless steel, super duplex stainless steel welded and seamless tubing, depending upon the properties the tubing is required to exhibit. Other alloys and sizes are also available upon request. Duplex stainless steels (named for their austenite and ferrite compositions), has greater yield strength than austenitic stainless steel.
Standard: ASTM-A 789 Standard specification for seamless and welded ferretic/austenitic stainless steel tubing for general service. This specification covers various grades of duplex stainless steels.
