Welded stainless steel pipe are created by forming sheets of steel in a tube shape and then welding the seam. Both hot-formed and cold-formed processes are used to create stainless tubing, with the cold process producing a smooth finish and tighter tolerances than hot forming. Both processes create a stainless steel pipe that resists corrosion, features high strength and durability.

Stainless steel pipe is also easily cleaned and sterilized and can be easily welded, machined, or bent to create a curved shape. This combination of factors makes stainless steel pipe an excellent choice for structural applications, especially those where the tubes may be exposed to corrosive environments

On November 1, 2024, the US International Trade Commission (USITC) instituted the third sunset reviews of anti-dumping (AD) and countervailing duties (CVD) on welded stainless steel pressure pipes from China, as well as the second sunset review of AD duties on the same products from Malaysia, Thailand, and Vietnam, to determine whether the cancellation of the existing AD and CVD orders on the subject products would be likely to lead to the continuation or recurrence of material injury to the US industry within a reasonably foreseeable time.

On November 4, the US Department of Commerce (USDOC) announced the initiation of the third AD and CVD sunset reviews on the subject products from China, as well as the second AD sunset review on the same products from Malaysia, Thailand, and Vietnam.

The interested parties should submit their response to this notice with the needed information by the deadline of December 2, 2024, and the comments on the adequacy of responses should be filed by January 2, 2025.

300 series grade stainless steel is manufactured into a range of products including steel tubes, steel pipes, and various other products. Both 304 and 316 steel tubes are nickel-based alloys that are easy to maintain, resist corrosion, and maintain strength and durability at high temperatures.

Determining which grade of steel is best for your application depends on the intended application as well as environmental factors such as temperature or exposure to chloride.

• Type 304 stainless steel is corrosion resistant and easy to sanitize, making it the most common type of stainless steel used for tubing and other steel parts. 304 stainless steel tubes are frequently used in building and decorating applications.
• Type 316 stainless steel is similar to 304 stainless in that it is also corrosion-resistant and easy to clean. 316 stainless does, however, have a slight advantage because but is more resistant to corrosion caused by chloride, chemicals, and solvents. This additional factor makes 316 stainless steel a preferred solution for applications where there is constant exposure to chemicals or for outdoor applications where there is exposure to salt. Industries that are known to use 316 stainless steel include industrial, surgical, and marine.
