generally , all erosion-resistant steels have sufficient abrasion resistance which can be improved through surface treatment, such nitriding, although it can reduce the erosion resistance property.
Only through multiphase material can high abrasion resistant be obtained. For instance, material with hard surface disperse phase ( such as carbide), wherein the carbon content, grain size and shape, carbide distribution as well as the hardness of matrix are all key factors influencing abrasion resistance.
Usually the abrasion resistance and erosion resistance interact with each other. For erosion-resistant steel, sufficient erosion resistance will be reached only when the chrome content in the matrix is higher than 13%.
Due to the high affinity between carbon element and chorme element, the chorme content in the matrix will usually reduce with the formimg of chromic carbide. Therefore, the increase of abrasion resistance will generally reduce erosion resistance property.
