What is the difference between A105 and WCB as valve body materials?

Reply #22023-03-27

A105 is a carbon steel material containing about 0.35% carbon, suitable for low-temperature and high-pressure applications； WCB is a low-carbon steel material containing about 0.25% carbon, suitable for applications under moderate temperatures and pressures. During the valve manufacturing process, different valve body materials are selected based on the operating environment and working pressure to meet the requirements. Therefore, the main differences between A105 and WCB lie in their carbon content, temperature resistance, and applicable applications. .

Apart from the difference in composition, A105 is forged steel while WCB is cast steel.

The difference between forging and casting. It has better forgeability; small sizes are forged.
