Stainless Steel 309H ERW Pipes

Stainless Steel 309H ERW pipes (Electric Resistance Welded) pipes have a chemical composition that consists primarily of iron, chromium (22-24%), nickel (13-15%), carbon (0.04-0.10%), manganese (2%), silicon (1%), and small amounts of other elements such as phosphorus, sulfur, and nitrogen. The high levels of chromium and nickel provide the material with outstanding corrosion resistance while adding carbon improves its toughness and strength. This specific type of stainless steel is suitable for high-temperature applications and is commonly used in manufacturing heat exchangers, boilers, and pressure vessels.

SS 309H ERW pipes have several uses and properties that make them popular in various industries. The high levels of chromium and nickel give the material excellent corrosion resistance, making it suitable for use in harsh and corrosive environments. Its toughness and strength, due to the presence of carbon, make it a reliable choice for high-temperature applications such as heat exchangers, boilers, and pressure vessels. Additionally, 309H stainless steel has good formability, weldability, and excellent resistance to oxidation and carburization. These properties make it a popular choice for various industrial applications, including petrochemical, power generation, food processing, and many others. Overall, 309H stainless steel ERW pipes are a versatile and reliable choice for demanding applications that require resistance to high temperatures and corrosive environments.
