316 / UNS No. S31600 / EN 1.4401
Stainless steel 316 are renowned for their exceptional corrosion resistance, making them highly sought-after materials in various industries. Compared to other grades of stainless steel, these alloys exhibit superior resistance to atmospheric and chemical environments. The key to their impressive corrosion resistance lies in their composition, which includes molybdenum, providing enhanced protection against pitting and crevice corrosion.
Stainless steel 316 seamless tube is a type of stainless steel tubing manufactured without welding joints, resulting in a continuous and smooth tube structure. It is specifically made from grade 316 stainless steel, which is an alloy containing a combination of chromium, nickel, molybdenum, and titanium. The addition of titanium provides enhanced resistance to corrosion, especially in high-temperature environments.
That sets them apart from standard 304 stainless steel, especially in chloride-rich environments, where 316 shows remarkable stability. Additionally, their low carbon content in 316 further minimizes sensitization issues during welding, ensuring long-term corrosion resistance. For marine applications, chemical processing, or harsh outdoor conditions, stainless steel 316 seamless tubes are reliable for enduring and corrosive-resistant solutions.
The key features of the stainless steel 316 seamless tube include its excellent corrosion resistance, even in aggressive and corrosive environments such as chemical processing, marine applications, and oil and gas industries. It offers superior strength and durability, making it suitable for applications where high mechanical stress and pressure are involved.
