Stainless Steel 348H Seamless Pipes

348H stainless steel is a type of austenitic stainless steel that contains a high level of chromium (17-19%) and nickel (9-13%) with a small amount of molybdenum (1.5-3%) and small amounts of other elements such as carbon (0.05-0.10%) and nitrogen. This combination results in high resistance to intergranular corrosion, particularly against stress corrosion cracking and pitting, making it ideal for high-temperature applications. Adding molybdenum to its composition provides improved resistance to pitting and crevice corrosion, and the high nickel content results in good resistance to general corrosion. 348H stainless steel also has good mechanical properties, strength, and ductility, making it suitable for many industrial applications, including chemical processing and oil and gas production. Overall, the chemical composition of 348H stainless steel results in a high-performing, durable and reliable material for a wide range of applications.

348H SS Seamless Pipes are commonly used in high-temperature and corrosive environments. These pipes are made of alloy 348H, which contains higher levels of chromium, nickel, and other elements that enhance its high-temperature stability and corrosion resistance compared to regular 348 stainless steel. The seamless design of these pipes eliminates any potential weak points, making them suitable for high-pressure applications. They also have excellent resistance to oxidation and decarburization, making them ideal for use in harsh chemical environments. In addition, they are easy to fabricate and can be machined to meet specific requirements, making them a popular choice in industries such as petrochemical, chemical processing, and power generation.
