(1) Many of the aerospace structural steels of the valve test bench are treated with quenching and tempering to achieve higher anti-fatigue function;
(2) The valve test bench widely uses isothermal phosphorous to achieve outstanding mechanical function, and should reduce the phosphorous distortion as much as possible;
(3) The valve test bench is widely used for chemical heat treatment such as carburizing and nitriding in order to obtain high wear resistance and anti-fatigue function;
(4) The valve test bench is designed to meet the requirements of high temperature oxidation resistance and corrosion resistance, and is selected from metal infiltration (such as aluminizing, siliconizing, etc.);
(5) Valve test bench Aviation martensitic stainless steel is treated with “phosphorus + tempering”.
