Gray cast iron 350 is a gray cast iron material with a tensile strength of not less than 350MPa. Its chemical composition standard refers to GB/T 9439-1988. Gray cast iron 350 is suitable for manufacturing mechanical machine bases that bear large loads, such as machine tool beds, punch press bases, and other supporting structures of heavy machinery. In addition, it is also used to manufacture steel rolling slides, rollers, cylinders for coke ovens, mixer gear rings, support wheel seats and other components.
Specific applications of gray cast iron 350 include:
Heavy machinery: used to manufacture support structures for heavy machinery, such as machine tool beds and punch press bases.
Steel rolling equipment: used to manufacture steel rolling slides and rollers to ensure the stability and durability of the steel rolling process
Metallurgical equipment: used for coke oven cylinders and mixer gear rings to adapt to high temperature and high pressure working environments.
Other components: also used to manufacture components such as support wheel seats to improve the overall stability and load-bearing capacity of the equipment.
