High Temperature Erosion Behaviors of High V-Cr-Ni Spheroidal Carbides Cast Iron

Abstract:

High temperature erosion occurs in production of the inorganic fibrous insulator in plant. Austenitic and martensitic stainless steels are often used for these severe high temperature erosion conditions. The paper presents erosion properties of some stainless steels, several cast iron and cast steel using a blast type high temperature erosion furnace. The solid particle erosion behavior at high temperatures (900°C) of carbon steel of S50C, carbon tool steel of SK3, SUS403, SUS630, and High V-Cr-Ni spheroidal carbides cast iron (SCI-VCrNi) are investigated. Alumina balls entrained in a stream of hot air impact on the target materials at an air velocity of 100 m/s. the impingement angle is 90°. The influence of the test temperature and the material removal are discussed. The high temperature erosion behaviors of specimens are discussed by the eroded surface morphology and vertical section observation using SEM and optical microscopy observations.
