Forged steel valve and Cast Steel valve products differrence
Forged steel valves and cast steel valves are two common types of industrial valves, which have significant differences in manufacturing processes, material properties, scope of use, price, and applicable scenarios. Here are their main differences:
1. Manufacturing process:
Forged steel valves are manufactured by heating the metal to the deformation temperature and then forging it. This process rearranges and strengthens the metal grains, thereby improving the performance of the material.
Cast steel valves are manufactured by melting, pouring, and cooling, with a relatively simple process.
2. Material properties:
The structure of forged steel valves is more uniform, with finer grains, thus possessing better toughness and impact resistance. This characteristic makes forged steel valves more stable and reliable when subjected to pressure, impact, and vibration.
The structure of cast steel valves is relatively dense, with high strength and hardness, but relatively low toughness.
3. Scope of use:
Forged steel valves are suitable for high temperature and high pressure, small-diameter valves, and industrial fields with high requirements, such as petroleum, chemical, metallurgy, etc.
Cast steel valves are suitable for large and medium-sized valves with lower temperature and its working temperature not exceeding 425 ℃.
4. Price:
Forged steel valves are relatively expensive due to their complex manufacturing process and superior material properties.
Cast steel valves are more competitive in some situations where cost control is required due to their relatively simple manufacturing process and lower cost.
5. Applicable scenarios:
Forged steel valves are commonly used in critical equipment or high-pressure fluid control systems due to their excellent performance.
Cast steel valves are suitable for producing complex shaped parts due to their good fluidity and formability.
The selection of suitable valve materials needs to be judged based on specific usage requirements. In practical applications, the appropriate valve type should be selected based on specific needs and scenarios. For example, in situations where high strength and toughness are required, such as high-pressure fluid control or critical equipment, forged steel valves may be a better choice; When it comes to producing parts with complex shapes and good fluidity, cast steel valves have more advantages.
