Seamless Stainless Steel Pipe 304

Seamless stainless steel pipe 304 is widely used in various fields because of their strong corrosion resistance, high strength, good workability, as well as high temperature and high pressure resistance and good sanitary properties. With a maximum service temperature of up to 925°C, good corrosion resistance in a wide range of acidic solutions, tensile strength of between 515-725 MPa, and a yield strength of up to 205 MPa, 304 seamless stainless steel tubes are impressive for their reliability and versatility.
