They are all made of steel; it seems that the difference lies in the composition of the material
Coming to learn*, same question~~? ?
Check the material on the valve body. . For example, WC6 is molybdenum steel. WC9 is molybdenum-vanadium steel. Some of them have 30CRMO written on them. 35CRMO。 If it’s not marked. There’s only the spectrometer. .

Chromomolybdenum steel is an alloy of chromium (Cr), molybdenum (Mo), iron (Fe), and carbon (C). Based on the content of these alloying elements, it can be classified as 1) low-alloy steel, where the total content of alloying elements is less than or equal to 5%； 2) Medium alloy steel: The total content of alloying elements is between 5% and 10% ； 3) High-alloy steel: Total content of alloying elements is greater than or equal to 10% ； 2. Classified by the type of alloying element, there are chromium steel, manganese steel, chromium-manganese steel, chromium-nickel steel, chromium-nickel-molybdenum steel, silicon-manganese-molybdenum-vanadium steel, etc. :lol
