Thickness Chart Of ASTM A403 WP321 Elbow And Biggest Manufacturer Of ASTM A403 WP 321 Stainless Steel Buttweld Pipe Fittings At Best Price And Fast Delivery.

The Grade 321 is used for common 18/8 stainless steel alloy, along with titanium. The Grade 321 steel is similar to that of the 304 grade, with additional titanium, which is at least five times the carbon content. The composition of Stainless Steel 321 Pipe Fittings makes it strong and capable of bearing harsh environments. We manufacture ASTM A403 WP 321 Stainless Steel Buttweld Pipe Fittings, which are used in various industries including Petrochemical, Nuclear, Oil and Gas, etc. We also specialize in manufacturing ASTM A403 WP321 Elbow, which comprises grade 321 stainless steel seamless tube with the diameter range of DN 15 to DN 1000. Largest Manufacturer Of ASTM A403 WP321 Pipe Fittings In China.

We are among the top stockists of ASTM A403 WP321 Pipe Fittings in China, where ASTM A403 is a standard of the pipe fitting material, which indicates the material properties of various types of stainless steel. WP321 is a steel grade in the given standard. Titanium acts as a stabilizing element in 321 SS Pipe Fittings, and its properties make it helpful in making wear-resistant pipeline equipment.

We manufacture different types of grade 321 pipe fittings like:

  • ● SS WP321H Buttweld Equal Tee‘s diameter of the branch is the same as that of the actual pipe.
  • ● Werkstoff Nr. 1.4541 Concentric Reducer extensively used in industries such as aircraft and missiles.
  • ● UNS S32100 Stub End reduces the cost of flange joints and speeds up the whole joining process of a pipeline system.
