Product Description

2205 Duplex Stainless Steel Capillary Coiled Tubing High Efficiency Tubing


2205 duplex stainless steel is a kind of stainless steel in which the proportion of ferrite phase and austenite phase in solid quenching is half and half, which is short for 2205 stainless steel. The actual phase ratio is ferritic 45~55% and austenite 55~45% accordingly. Excellent performance of 2205 duplex stainless steel depends on the appropriate proportion of the two-phase structure to ensure. 2205 duplex stainless steel tubes have excellent mechanical properties and corrosion resistance, as well as good weldability, and are widely used in the petroleum and natural gas industry, Marine engineering, chemical industry and other industries.


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.
