The wear-resistant plate A514 grade E QT steel plate shows good wear resistance: the chemical composition of the alloy layer contains 4-5% carbon and 25-30% chromium. The volume fraction of Cr7C3 carbide in the metallographic structure is more than 50%, the macro hardness is HRC56-62, and the hardness of chromium carbide is HV1400-1800. Because of the vertical distribution of carbides in the wear direction, the wear resistance of the cast alloy with the same composition and A514 grade E QT steel plate hardness is more than twice as that of the cast alloy with the same composition and hardness. Compared with several typical materials, the wear resistance is as follows: (1) compared with low carbon steel; 20-25:1 (2) with as cast high chromium cast iron; 1.5-2.5:1.
The acicular ferrite pipeline steel can inhibit the formation of polygonal ferrite, promote the acicular ferrite transformation, and improve the precipitation strengthening effect of carbon and niobium nitride by adding molybdenum to reduce the transformation temperature of polygonal ferrite, so as to improve the strength of steel and reduce the ductile brittle transition temperature. The A514 grade E QT steel plate, tempered sorbite pipeline steel adopts the heat treatment process of quenching and tempering. The tempered sorbite structure is formed to meet the comprehensive requirements of thick wall, high strength and sufficient toughness.
Q235 is a kind of carbon steel. A514 grade E QT steel plate, Q235 steel is widely used in steel structure construction because of its good toughness, good plasticity, certain elongation, good welding performance and heating performance.
