Cast Iron Valves VS Cast Steel Valves :

Valves according to the material can be divided into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316, etc.), chrome molybdenum steel valves, chrome molybdenum vanadium steel valves, dual-phase steel valves, plastic valves, non-standard customized valve materials.

Material strength and hardness :

Cast iron valves: 

gray cast iron, ductile iron and other made.

Higher toughness and impact, lower hardness and strength.

Cast steel valves:

Alloy material composed of carbon and other alloying elements.

Higher strength, hardness and wear resistance.

Corrosion resistance:

Cast iron valves used in more corrosive media, vulnerable to corrosive influences, valve life is shorter.

Cast steel valves: corrosion resistance, suitable for corrosive media requirements of the scene.
