The valve is composed of the valve head and the stem. The temperature of the valve head is very high (intake valve 570~670K, Exhaust Valve 1050~1200K), and it also withstands the pressure of gas, the force of valve spring and the inertia force of the transmission component. The lubrication and cooling conditions are poor, and the valve must be required. Has a certain strength, stiffness, heat and wear resistance. The intake valve is generally made of alloy steel (chrome steel, nickel-chromium steel), and the exhaust valve is made of heat-resistant alloy (silicon chrome steel). In order to save the heat-resistant alloy, the exhaust valve head is made of a heat-resistant alloy, and the rod portion is made of chrome steel, and then the two are welded together.
