The difference between cast steel, cast iron and carbon steel valve materials

To put it simply, you first distinguish between iron and steel. Both steel and iron are alloys based on iron and carbon as the main additive element, collectively referred to as iron-carbon alloys. Smelt the cast iron in an iron melting furnace to obtain cast iron (liquid), and cast the liquid cast iron into castings. This kind of cast iron is called cast iron. What is the difference between cast steel and carbon steel. First, steel is classified according to chemical composition (1) Carbon steel: a. Low carbon steel (C≤0.25%); b. Medium carbon steel (C≤0.25~0.60%); c. High carbon steel (C≤0.60%) ). Steel is classified by forming method: (1) Forged steel; (2) Cast steel; (3) Hot rolled steel; (4) Cold drawn steel. The so-called cast steel and carbon steel are just the names produced by the different classifications of steel.
