The thickness of steel that a water jet can cut through depends on a variety of factors, including the type of steel, the hardness of the steel, and the power of the water jet machine. In general, water jet cutting can cut through steel up to several inches thick, but the exact thickness will depend on the specific parameters of the project.For example, a water jet with a pressure of 60,000 psi can typically cut through steel up to 6 inches thick, while a water jet with a pressure of 90,000 psi can cut through steel up to 10 inches thick. Of course, the specific cutting thickness should be determined according to the actual situation of the steel, because there are many types of steel, and the maximum cutting thickness of different types may have some differences..It is important to note that cutting thicker steel with a water jet can be a time-consuming process, and the cost can vary depending on factors such as the size of the piece being cut and the complexity of the design.
