| Abstract: | In view of the working conditions of high-pressure hydrogenation valves, the requirements of casting material were presented. The casting technological parameters of austenitic stainless steel valve body and the casting defects in production process were analyzed. A series of process improvements, including gating and riser, molding sand, melting and pouring, cleaning and heat treatment, were taken. The testing results of chemical component, mechanical property, microstructure, nondestructive inspection, measurement and appearance for valve casting all reach to normative requirements |
