DIN 17175 St45.8 Seamless Steel Pipe
DIN 17175 St45.8 carbon steel pipes are commonly used in the construction of power plants, refineries and various industrial plants. The minimum yield strength of St45.8 seamless pipe is 255 MPa and the minimum tensile strength is 410 MPa. The tube has the characteristics of high thermal conductivity, long service life, high temperature and high pressure resistance.
DIN 17175 St45.8 Seamless steel tubes are high pressure boiler tubes made of carbon steel and low alloy steel. These pipes can withstand high temperatures and pressures and are suitable for use in power plants, chemical plants and other industrial applications that require high-performance pipes.
St45.8 carbon steel pipe has better toughness, which means it is less likely to break when subjected to shock or vibration. This good toughness is conducive to withstanding dynamic loads, allowing the material to perform well in various dynamic environments.
St45.8 Seamless Steel Pipe is produced using a seamless extrusion process with a smooth surface finish and excellent dimensional accuracy. They are characterized by high strength and good weldability, which makes them suitable for a wide range of applications.
