304 stainless steel is the most widely used chromium-nickel stainless steel. As a widely used steel, it has good corrosion resistance, heat resistance, low temperature strength and mechanical properties; it has good hot workability such as stamping and bending, and No heat treatment hardening phenomenon. Suitable for food processing, storage and transportation. Has good processability and weldability.

Cast iron refers to the assembly of cast iron-carbon alloys with a carbon content of more than 2%. In addition to iron and carbon, the main elements include silicon, manganese and a small amount of phosphorus and sulfur. The production cost is low, the manufacturability is good, the casting performance is good, the melting point is low, the fluidity is good, the shrinkage is small(only 0.5~1.0%), good cutting performance. High wear and abrasion resistance, excellent vibration damping and low notch sensitivity.
