What is the Difference between Ductile Iron and Carbon Steel Valves?

Comparison of Material Characteristics:

1. Ductile iron: Ductile iron, also known as ductile iron or nodular iron, is a casting material that embeds graphite spheres into a cast iron matrix. It has high strength, corrosion resistance, and wear resistance, as well as certain impact energy absorption and shock resistance.

2. Carbon steel: Carbon steel is a type of steel with a high carbon content, which has excellent mechanical strength and rigidity, as well as good corrosion resistance.

Performance comparison:

1. Strength and corrosion resistance: Ductile iron has higher strength and corrosion resistance than carbon steel, making it particularly suitable for use in humid, corrosive, and corrosive media.

2. Resilience and impact energy absorption: Compared to carbon steel, ductile iron has better toughness and impact energy absorption, and can better maintain stability under impact or vibration conditions.

3. Rigidity and hardness: Carbon steel has higher rigidity and hardness compared to ductile iron, and is more stable under high pressure conditions.

Comparison of application areas:

1. Ductile iron: Due to its excellent corrosion resistance and strength, ductile iron is often used in industries such as chemical, petroleum, natural gas, and water treatment, especially in humid environments.

2. Carbon steel: Carbon steel has good rigidity and wear resistance, and is often used in water supply, natural gas pipelines, and general industrial equipment. Its strength and hardness make it more suitable for high pressure and high temperature conditions.
