Wear resistant plate is composed of two parts, namely carbon steel plate and alloy wear-resistant layer. Under normal conditions, the thickness of the Q295NH weathering steel GB/T 4171 plate alloy wear-resistant layer of the wear-resistant plate is 1 / 3-1 / 2 of the total thickness. When working, the matrix provides the strength, toughness, plasticity and other comprehensive properties to resist external forces, and the alloy wear-resistant layer provides the Q295NH weathering steel GB/T 4171 plate wear-resistant property to meet the requirements of specific working conditions.
Q295NH weathering steel GB/T 4171 plate, The wear-resistant composite plate is quenched once and tempered at low temperature. The quenching temperature is 820-850℃ or 780-810℃. If the strength of the core is required to be higher, it should be quenched at 820-850℃ with low carbon M at the core. If the surface hardness is required to be high, the grain size can be refined by quenching at 780-810℃. It is suitable for solid carburized carbon steel and low alloy hardfacing wear-resistant composite plate workpieces, and coarse grain steel carburized by gas and liquid.
