15CrMoG Steel Pipe Performance and Application Details

Both 15CrMoG boiler steel pipes and 15CrMoG high-pressure steel pipes are made of the same material. The following is a detailed introduction to these two types of 15CrMoG steel pipes:

First, 15CrMoG Boiler Steel Pipes

15CrMoG boiler steel pipes are alloy high-pressure boiler steel pipes. They are made from high-quality carbon structural steel with the addition of one or more alloying elements to enhance the steel's mechanical properties, toughness, and hardenability. Products made from this steel typically undergo heat treatment (normalizing or quenching and tempering). Parts and components made from this steel typically undergo quenching and tempering, surface chemical treatment (such as carburizing and nitriding), surface hardening, or high-frequency hardening before use. Based on their chemical composition (primarily carbon content), heat treatment process, and intended use, 15CrMoG boiler steel pipes can be broadly categorized as carburized, quenched and tempered, and nitrided steels. This type of steel is mostly rolled (forged) into round, square, and flat sections and seamless steel pipes. It is primarily used to manufacture important and large parts and components in mechanical products, as well as high-pressure piping and containers. It offers superior overall mechanical properties compared to high-quality carbon structural steel.

Second, 15CrMoG High-Pressure Steel Pipes

15CrMoG high-pressure steel pipes are seamless steel pipes. Due to different manufacturing processes, they are divided into hot-rolled (extruded) seamless steel pipes and cold-drawn (rolled) seamless steel pipes. Cold-drawn (rolled) pipes are further divided into round and special-shaped pipes. 15CrMoG steel is a heat-resistant steel with a pearlite structure. It exhibits high thermal strength (δb ≥ 440 MPa) and oxidation resistance at high temperatures, as well as a certain degree of resistance to hydrogen corrosion. However, due to the high content of Cr, C, and other alloying elements, the steel exhibits a significant tendency to harden and poor weldability. Furthermore, 15CrMoG high-pressure steel pipes are recyclable, aligning with national strategies for environmental protection, energy conservation, and resource conservation. National policies encourage the expansion of 15CrMoG high-pressure steel pipe applications.

Third, Applications and Standards of 15CrMoG Steel Pipes

15CrMoG boiler steel pipes and 15CrMoG high-pressure steel pipes are widely used in various high-pressure, high-temperature, and corrosion-resistant applications. They comply with a series of national and industry standards, such as GB5310-2008 (Seamless Steel Pipes for High-Pressure Boilers). These standards specify the pipe materials, manufacturing processes, and performance requirements, ensuring pipe quality and reliability.

Fourth, Summary

15CrMoG boiler steel pipes and 15CrMoG high-pressure steel pipes are both high-quality high-pressure steel pipe materials with excellent performance and a wide range of applications. They comply with national and industry standards, ensuring pipe quality and reliability. When selecting and using these pipes, the appropriate pipe material and specifications should be selected based on the specific application environment and requirements.
