Grade 16Mo3 seamless alloy steel pipe is a high quality steel pipe suitable for high temperature applications. The steel tubes are reheated and supplied in fully annealed, isothermal annealed or normalized quenched and tempered conditions with excellent mechanical properties.
16Mo3 alloy steel pipe has a typical chemical composition with the addition of 0.25-0.35 molybdenum, which helps improve its high temperature resistance and mechanical strength. The steel pipe has a minimum tensile strength of 450 MPa, a maximum tensile strength of 600 MPa, and a minimum yield strength of 280 MPa. These data provide an understanding of the mechanical properties of steel pipes, allowing them to withstand certain loads and stresses in high temperature environments.
DIN 17175 16Mo3 pipes are widely used in several industries, including power engineering, chemical plants, oil and gas, petrochemicals and shipbuilding. These pipes play an important role in various equipment such as steam superheaters and reheaters, boiler tubes, heat exchangers, condensers, pressure vessels and other equipment, etc. They excel in these applications, providing stable and reliable piping systems for a variety of industrial processes.
