industrial pump components made by gray iron


Ductile castings and gray irons, due to their excellent performance, can sometimes replace expensive cast steel and forged steel in use, and are widely used in the machinery manufacturing industry. The research and development of high-quality nodular cast iron parts and gray iron parts are mainly concentrated in thick and large parts. They are used in large-scale equipment fields such as metallurgy, mining, transportation, power, and machining. Their working conditions are difficult, maintenance is difficult, and continuous operation is required. Working for more than 10 years, so the internal and external quality requirements of the casting are extremely high. The energy demand is increasing day by day, and the emerging industry wind power generation has gradually developed and expanded with its unique advantages. Many of the core cast iron markets are cast iron or cast steel parts such as nodular cast iron parts such as hubs, spindle seats, etc. Due to special use conditions, It has good mechanical and physical properties such as elongation, impact work and nodularity.

Features of gray iron and ductile iron castings:

1. The tensile strength is relatively low.

2. Good abrasion resistance and shock absorption.

3. Good process performance, such as casting fluidity, machinability is better than steel.
