Study on the Materials for Valve Seating at High Temperature and High Pressure (5th Repert)

Abstract

Following the 4th report, the authers studied the abrasion test, thermal expansion coefficient, high temperature hardness, corrosion, test in comparison with the stellite and 65%Ni-Cu-Cr-Si-Fe series alloy for materials of valve seatings at high temperatureand high pressure.
The results of the experiments shewed that stellite was superier to 65%Ni-Cu-Cr-Si-Fe series alloy for valve seatings.
