Cast Iron and Ductile Iron tube and fittings PL739
Cast Iron and Ductile Iron tube and fittings can be offered by our comapny to meet different engineering needs.
The difference between ductile iron and gray iron
1. Different chemical composition
Nodular cast iron contains nodular graphite, which can improve its toughness and strength, while reducing brittleness. Gray cast iron contains a lot of carbon, so that its hardness and wear resistance is high, but the toughness is poor.
2. Different organizational structures
The structure of nodular cast iron contains nodular and ferrite, and the distribution of nodular is uniform. While the structure of gray cast iron is mainly ferrite and pearlite, and the distribution of pearlite is uneven.
3. Different performance
Ductile iron has high strength and toughness, and has good corrosion resistance. It is uitable for the manufacture of high load and high pressure parts. The hardness and wear resistance of gray cast iron are high. It is suitable for the manufacture of friction and wear parts.
Application field
Cast iron : because of its low strength and good vibration resistance. It is often used in the production of parts under compressive stress, such as box, base, etc.
Ductile iron : because of its high strength and good toughness. It is often used in the manufacture of parts requiring high strength and toughness, such as crankshaft, connecting rod and so on.
Circular steel pipe is both openings and have hollow concentric sections of steel larger than the surrounding. The specifications of steel pipes are indicated by appearance dimensions and inner diameter and wall thickness, with a wide range of dimensions from very small diameter capillary to large round steel pipe of several meters in diameter. Round steel pipes can be used for pipelines, thermal equipment, machinery industry, petroleum geological drilling, containers, chemical industry, and special uses. It can be divided into seamless, ERW, LSAW, SSAW steel pipe according to the production process.
