The main difference between forged steel and cast steel ball valves


What is the difference between a forged steel ball valve and a cast steel ball valve? The difference mainly lies in the processing technology and processing method of steel:

A cast steel ball valves is a kind of ball valve that is formed by pouring liquids into a mold and then allowing them to solidify. Alloy steel is the most common casting material. Cast steel is divided into cast carbon steel, cast low alloy steel and cast special steel. Cast steel refers to a steel casting produced by a casting method. Cast steel is mainly used to make parts that are complex in shape, difficult to forge or cut, and require high strength and plasticity.

Forged steel ball valves are various ball valves with forged steel and forged pieces produced by forging process. Forged steel ball valves are stronger than cast steel ball valves and can withstand large impact forces. Their plasticity, toughness and other mechanical properties are also higher than that of castings, so for some important machine parts, forged steel parts should be used.

Casting is liquid molding, while forging is a plastic deformation process. With improved internal structure, good mechanical properties and even grain texture, the forged workpiece is the perfect choice for important heavy-duty parts. The casting will cause structural segregation, structural defects, and of course, casting has its own advantages. The forming of complex workpieces is not easy to be done by forging, in this case, casting process is more favorable.
