27simn seamless steel pipe, ie 27SiMn seamless steel pipe

27simn seamless Steel Pipe that is 27 silicon manganese seamless steel pipe, is a kind of seamless steel pipe material, carbon content between 0.24-0.32%, simn a single column because it is because of the five elements (carbon C, silicon Si, manganese Mn The phosphorus, sulfur S), silicon manganese content is about 1.10-1.40%. 27simn Seamless Pipe is suitable for power plant, boiler plant, chemical industry, car, ship accessories.
27SiMn, alloy structural steel. Unified digital code: A10272
Standard: GB/T 3077-1999
[27simn seamless steel pipe main features]
The performance of this steel is better than 30Mn2 steel, high hardenability, critical quench-through diameter in water up to 8 ~ 22mm, good machinability, cold deformation plasticity and weldability; In addition, the toughness of steel in heat treatment is not much reduced, However, it has relatively high strength and wear resistance, especially when water quenched, it still has high toughness; however, this steel is sensitive to white spots, and has tempering brittleness tendency and overheating sensitivity during heat treatment.
[27simn seamless steel pipe application example]
This steel is mainly used in the tempered state for the manufacture of hot stamping parts requiring high toughness and wear resistance; it can also be used in the normalized or hot rolled state of supply, such as the tractor's track pins.
