27SiMn steel pipe is one of the materials of seamless steel pipe, the carbon content is between 0.24-0.32%, simn single column because because of the five elements (carbon C, silicon Si, manganese Mn, phosphorus P, sulfur S), the content of silicon manganese is about 1.10-1.40%. 27simn seamless pipe is suitable for power plant, boiler plant, chemical industry, car, ship accessories, etc. The performance of 27SiMn steel pipe is better than 30Mn2 steel, the hardenability is higher, the critical quenching diameter in water is 8 ~ 22mm, the machinability is good, the cold deformation plasticity and weldability are medium; In addition, the toughness of steel is not much reduced during heat treatment, but it has quite high strength and wear resistance, especially when water quenching, it still has high toughness; However, the steel is sensitive to white spots and has a tempering brittleness tendency and overheating sensitivity during heat treatment.
High temperature applications: 27SiMn welded steel pipes usually have good high temperature stability and can work stably in high temperature environments, such as in the application of heat or gas transmission in high temperature pipelines.
Low temperature application: For low temperature applications, especially in cold climate conditions, the selection of 27SiMn steel pipe should consider its low temperature toughness and cold resistance.
