What material is the valve WCB

We often see various valves in our daily lives, and there are many valve materials, and the characteristics of different materials are different. So what kind of material is the valve WCB?

It belongs to low-carbon steel. WCB is the number of the valve material. Its carbon content is normally maintained between 0.3% and 0.5%. The materials of WCB include carbon, manganese, phosphorus, sulfur, silicon and so on. It is an American cast steel grade, corresponding to the domestic cast steel grade ZG30-450, and it has greater design flexibility, the strongest flexibility and variability in metallurgical manufacturing, improved overall structural strength, and a wide range of weight changes , The price is low, and the solderability and usability of this attribute can be improved in a large range.

Its chemical composition:

  C≤0.30; Si≤0.60; Mn≤1.00; P≤0.040; S≤0.045; impurity elements Cr≤0.5; Mo≤0.20; V≤0.03; Ni≤0.50; Cu≤0.30; total impurities ≤1%.

Note: For every 0.01% decrease in C, Mn can increase by 0.04%, but the maximum Mn cannot be higher than 1.28%.
