What are the differences between cast steel and cast iron?

The essential difference between cast iron and cast steel lies in their different chemical compositions. In engineering, it is generally considered that iron has a carbon content higher than 2%, while steel has a carbon content lower than this value. Due to the different compositions, the microstructure and properties are also different. Generally speaking, cast steel has good plasticity and toughness, exhibiting good elongation, area reduction, and impact toughness, while cast iron has hard and brittle mechanical properties.

The role of five elements in cast iron parts

Cast iron is a cast iron-based alloy with a carbon content of more than 2%, and also contains silicon and small amounts of elements such as manganese, phosphorus, and sulfur. White cast iron, gray cast iron, and ductile iron are common. The conventional elements of cast iron are carbon, silicon, manganese, sulfur, and phosphorus, which are our five major conventional elements and are important factors that directly affect the mechanical properties of castings.

Some knowledge points of cast iron

Compared to carbon steel, cast iron has a higher content of C and Si in its chemical composition (C 2.5% ~ 4.0%, Si 1.0% ~ 3.0%), higher impurity elements Mn, P, S, and alloy elements in some alloy cast irons with special properties. The presence and content of all these elements will directly affect the structure and properties of cast iron.

What is the function of the valve body?

It is the valve core part of the valve body. Commonly used materials include ceramic valve cores and copper valve cores. It is mainly used in water valves and air valves to block water flow or airflow within the valve. Overall replacement is common. The choice is to buy a valve where the valve core can be replaced separately, without removing the valve, and directly replacing the valve core.
