Q345NH weathering plate is a high-quality alloy steel with high strength, good toughness and hardenability. It cannot be directly quenched after carburizing to reduce surface retained austenite. Machinability and cold deformation plasticity are average. Weldability is poor. It needs to be preheated to about 150℃ before welding. It has strong white point sensitivity during working hours and tends to be tempered and brittle. Q345NH weathering plate A is used for large section carburizing parts, such as large gears, shafts, and quenched and tempered parts that require high strength and toughness.
Processing capacity
Cutting (band saw, flame, laser, plasma, water jet), precision cutting, surface grinding
Q345NH weathering plate has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance and corrosion resistance, especially its high hardness and wear resistance, which remains basically unchanged even at a temperature of 500℃ Still high hardness at 1000 ℃.
Q345NH weathering plate is widely used as cutting tool materials, such as turning tools, milling cutters, planers, drills, boring tools, etc., for cutting cast iron, non-ferrous metals, plastics, chemical fiber, graphite, glass, stone, and ordinary steels. It can also be used for cutting. Refractory materials such as heat-resistant steel, stainless steel, high-manganese steel, and tool steel.
