ZG34CrMoA is a type of large steel ingot with a melting point of 3400-3460 ℃, produced by using smelting technology. This type of steel is non-magnetic and has very low sulfur and phosphorus levels. It has an excellent property of heat resistance after appropriate heat treatment. ZG34CrMoA is typically used to manufacture components that are subject to thermal fatigue, wear and corrosion, such as valves, turbine blades, wheel discs and other components of power machinery and vehicles. Furthermore, this steel can be used for construction of bike frames, bridge parts, industrial and agricultural machines.
Due to its excellent wear and corrosion resistance, ZG34CrMoA is widely used in aerospace engineering, power generation and heavy industry. The high wear resistance of this steel makes it ideal for components that are to be exposed to the strength of heat, the pressure of impact and the effects of a corrosive environment. Moreover, its high strength makes it suitable for components that require larger mechanical components such as wheel axles, screw threads and shafts.
However, it should be noted that ZG34CrMoA is also subject to non-metallic inclusions, which can potentially weaken the structural integrity of the steel components. Non-metallic inclusions comprise particles such as clay, slag, sand, refractory material, and other unwanted substances, which are usually formed during steel processing. If these inclusions are not removed properly, they can lead to defects in manufacturing and, during operation, can reduce the steel component’s strength and durability. Furthermore, non-metallic inclusions can also weaken a component’s internal and external structure, leading to component breakage, cracking, or loss of structural integrity. In extreme cases, non-metallic inclusions can lead to component failure, resulting in serious injuries and loss of life.
Thus, it is important to ensure that ZG34CrMoA steel is free from non-metallic inclusions. To do this, steel components should undergo regular preventive maintenance measures such as cleaning, inspection, and welding. Chemical and physical analysis of the steel should also be performed on a regular basis, both to detect existing non-metallic inclusions and to determine the amount of such inclusions that is acceptable for a specific application. If the amount of inclusions is determined to be excessive in a component, further processing such as heat treatment or alloying should be done to reduce such content. Finally, experienced personnel should be consulted with regard to the selection, handling, and processing of ZG34CrMoA steel, to ensure safe and efficient operation of steel components.
