What is Stainless Steel 316H Seamless Pipe, and its key characteristics?
Stainless Steel 316H Seamless Pipe is a type of pipe made from stainless steel alloy 316H, a high-carbon modification of the popular 316-grade stainless steel. This grade is designed for high-temperature applications and exhibits excellent mechanical properties, corrosion resistance, and high-temperature strength. Stainless Steel 316H Seamless Pipe's key characteristics include its exceptional corrosion resistance in various corrosive environments, such as acids, alkalis, and chloride solutions.
Table Of Content
It also offers excellent weldability and formability, making it suitable for various industrial applications. Furthermore, the high carbon content in 316H enhances its high-temperature strength and provides superior creep resistance, making it ideal for applications involving elevated temperatures or thermal cycling. Stainless Steel 316H Seamless Pipe is durable and reliable for demanding applications requiring corrosion resistance and high-temperature performance.
What are the advantages of using Stainless Steel 316H Seamless Pipe over other materials?
Using Stainless Steel 316H Seamless Pipe offers several advantages over other materials. First and foremost, its excellent corrosion resistance makes it highly suitable for applications in harsh environments where exposure to corrosive substances is a concern. The alloy's chromium content forms a passive oxide layer on the surface, providing a protective barrier against corrosion, including pitting and crevice corrosion. Additionally, including molybdenum enhances its resistance to chloride-induced corrosion, making it particularly useful in marine and coastal applications.
Another advantage of Stainless Steel 316H Seamless Pipe is its high-temperature strength and performance. The high carbon content in 316H improves its tensile strength, creep resistance, and resistance to intergranular corrosion at elevated temperatures. That makes it a reliable choice for applications that involve exposure to high temperatures or thermal cyclings, such as in power plants, chemical processing, and oil and gas industries.
The seamless manufacturing process ensures that Stainless Steel 316H Seamless Pipe has a smooth and uniform surface, minimizing the risk of leaks, cracks, or weak points. The absence of welded seams enhances its structural integrity, making it a reliable and durable option for various applications.

Rolling and welding
Firstly, the stainless steel strips are made to gone through various quality checks and are trimmed at edges. They are then fed to the tubes mill by stainless steel pipe manufacturers in India. The strips pass through the number of rollers as per the required size. In the tubes-mill, the strip is gradually converted into the tubular shape. The fitted welding machine is then used to weld trim edges of the strip using TIG welding process. The scraps and inside weld bead are removed instantaneously by the Tibo machine. In this way, rolled pipes and tubes are formed.
The cleaning and heating phase
The rolled stainless steel seamless pipes thus manufactured are cut to the required lengths depending upon the industrial demand. These stainless pipes and tubes are then subjected to cleaning to remove the dirt. Further, a heat treatment is given to these rolled pipes and tubes to remove the stresses that may occur due to welding and formation processes. Heat treatment is given on the continuously rolling hearth furnace. The furnace is fitted with temperature recorders and controllers. After the heat treatment process, the SS tubes and pipes are straightened and subjected to pickling for removing scales from the surface.
Cold- drawing process
In some cases, the required size may not be obtained from the mill directly. Then, the cold operation process can be used to obtain the desired size. In cold drawing process, the tubes or pipes are coated with oxalic and soap solution. This solution acts as a lubricant to reduce friction while cold drawing operation. In the cold drawing process, the tube or pipe is drawn over the bench using Die plugs.
Finishing process
The drawn-out tube or ss pipe is then subjected to cleaning, heat treatment, pickling and straightening. The computerized ink jet marking machine is used to do the marking on the finished pipes or tubes. The pipe or tube is marked with grade of material, size, heat number and the stamp of third party inspection before passing on to stainless steel pipe exporters. The stainless tubes or pipes thus produced will undergo certain testing and quality checks. This process is followed by proper packing and dispatch. There are numerous numbers of stainless steel pipe applications, these pipes and tubes are used thereafter for.
