S460QL1 steel pipe erw steel pipe pile supplier

15MnNi steel plate is used for nuclear safety second and third grade pressure vessel steel. Since nuclear power equipment is used in harsh environments such as high temperature, high pressure and neutron radiation all year round, the steel S460QL1 steel pipe for equipment manufacturing is required to have suitable strength, high toughness, and low brittle transition temperature. The characteristics of strong performance and anti-radiation ability and low alloy element content, so there are strict requirements in room temperature stretching, high temperature stretching, thickness direction stretching and hardness.

The microstructure of the quenched and tempered alloy steel, S460QL1 steel pipe after conventional heat treatment is tempered sorbite. For parts with wear-resistant surface (such as gears and spindles), induction heating surface quenching and low-temperature tempering are carried out, and the surface structure is tempered martensite. The surface hardness can reach 55HRC-58HRC. After quenching and tempering, the yield strength of quenched and tempered alloy steel is about 800MPa, the impact toughness is 800kJ / m2, and the core hardness is 22HRC - 25HRC. If the cross-section size is large but not quenched, the properties will be significantly reduced.

The advantage of plasma cutting is that it can cut thin plates, stainless steel and non-ferrous metals, and the cutting speed is fast. The disadvantage of plasma cutting is that the incision will have a slope, and there will be noise when cutting. The advantages of water jet cutting are wide cutting range and environmental protection, but the disadvantages of water jet cutting are slow cutting speed and high energy consumption. Do you know what is the best cutting method for S460QL1 steel pipe?
