[0002] Steel castings are a type of cast steel material parts, which refer to parts made of cast steel. They have similar properties to cast iron, but are stronger than cast iron. Steel castings need to be heat treated during processing, and heat treatment devices are equipment used to heat treat cast steel parts. Steel castings usually need to be heat treated to improve their mechanical properties, wear resistance, corrosion resistance, dimensional stability and other properties.
