we often see forged steel ball valves and cast steel ball valve. But for the difference between them is certainly not to understand. Small make up today is to introduce the different between them.

cast steel ball valves and forged steel ball valve:

their difference is mainly reflected in four aspects:

1: steel forging process.

2: processing in a different way.

3: different pressure

4: the price is different.

1: differences between process: cast steel is used to pouring casting of steel. Cast steel can be divided into cast carbon steel, cast low alloy steel and special steel casting 3 classes. Cast steel is to point to the casting method and produce a kind of steel castings. Cast steel is mainly used in the manufacture of some complicated shape, difficult to forging or machining shape and required high strength and plastic parts. Then we process according to the casting of abrasive), and finally complete customer need forged steel ball valve products.

2: the processing method is introduced and different: : forged steel refers to the forging method and produce all kinds of forging and forging. Forged steel parts quality is much higher than steel, can bear the impact of the big role, plasticity, toughness, and other aspects of the mechanical properties were also higher than steel, so that some important machine parts should be the steel forging. For example, some large engineering, chemical industry, oil need to be need more forged steel ball valve series.

we are ordinary casting liquid forming, and forging is plastic deformation process, the forging forming workpiece can improve the organization structure, mechanical performance is good, uniform grain, important demanding workpiece must be forging, casting can cause tissue segregation, tissue defects, casting has his advantage, of course, forging forming complex workpiece is not easy to open mold, has taken the casting.

3: pressure difference: we are the material of forged steel ball Industrial Valves maximum pressure can reach 420 kg, and cast steel are generally has 100 kg as the highest pressure.

4: the price is different: forged steel ball valves in the process and difficulty of processing way than cast steel ball valve and requirements are greatly improve a lot, of course the price also is a lot more expensive than cast steel ball valve.
