What Is 2205 Stainless Steel Pipe

What is 2205 stainless steel pipe

As a duplex stainless steel, it combines the ideal properties of austenitic and ferritic steel grades. High chromium, molybdenum and nitrogen contents result in a Pitting Resistance Equivalency Number (PREN) of 33-34, providing superior pitting and crevice corrosion resistance to Alloy 316L or Alloy 317L austenitic stainless steels in almost all corrosive media. Due to its excellent corrosive properties, it is ideally suited for environments containing chloride and hydrogen sulfide, and is used to extract oil and gas from sour wells, refineries and process solutions contaminated with chloride.

2205 duplex ss tube is a nitrogen-added duplex stainless steel that has high strength, good impact toughness, and good overall and local stress corrosion resistance. 2205 Duplex Steel is particularly suitable for use in the -50°F/+600°F temperature range. This alloy may also be considered for applications outside this temperature range. The main feature of 2205 duplex stainless steel is that the yield strength can reach 400-550MPa, which is twice that of ordinary austenitic stainless steel. This feature allows designers to reduce weight when designing products, so they can save materials. This alloy is stronger than 316 and 317L It also has a price advantage and reduces equipment manufacturing costs. In terms of corrosion resistance, especially in harsh medium environments (such as seawater, high chloride ion content), the resistance to pitting corrosion, crevice corrosion, stress corrosion and corrosion fatigue of duplex stainless steel is significantly better than that of ordinary austenite. Stainless steel, comparable to high-alloy austenitic stainless steel. Due to the special performance characteristics of 2205 dual-phase steel, the types include bars, wires, welded pipes, seamless pipes, steel plates, forged materials, strips, etc., and have a wide range of applications. It is currently the most widely used grade among duplex steels.

SS pipe seamless duplex is a general-purpose stainless steel pipe. It is widely used in the manufacture of pipes for production and domestic water, low-pressure fluids and other media, and industrial gas. It is mainly used to make various gas appliances, such as liquefied petroleum gas stoves, Tianna water supply water heater, gas tank, petroleum cracking furnace heat exchanger and its connecting parts and public engineering piping.
