1 / 4 * 0.049 Duplex 2205 Stainless Steel ControL Line Tubing ASTM A789

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.

Super duplex stainless steel 2507 (S32750) is a kind of stainless steel that PREN>40, containing 25%Cr and high molybdenum (>3.5%), high nitrogen (0.22% ~ 0.30%). 2507 duplex stainless steel has strong strength and corrosion resistance. It is mainly used in chemical processing, petrochemical industry and subsea equipment.It has strong resistance to chloride corrosion, high thermal conductivity and low coefficient of thermal expansion.The higher the content of chromium, molybdenum and nitrogen, the higher the resistance to spot corrosion, crack corrosion and general corrosion.

The chemical composition is shown in the following table:

2507 control line tube is also one of our most competitive products, we have rich processing and supply experience. Our products are standardized and international, meeting ASTM A789 and all relevant industry standards, and have been exported to overseas markets in large quantities for many years.

Our products have complete specifications and can meet all working conditions. Our outer diameter range of 2507 tube is from 1/8" to 1/2". All dimensions and corresponding parameters are listed in the table below, we can also customize it according to customers' special requirements.
