Can valve parts forgings still maintain stable performance at high temperatures?

The performance stability of valve parts forgings at high temperatures mainly depends on material selection, forging process, and heat treatment process. Forging can effectively improve the structure of metals, giving them better strength, corrosion resistance, and wear resistance in high-temperature environments. At high temperatures, the grain structure of metals is more uniform, which can better withstand thermal expansion and pressure fluctuations, reduce deformation and fatigue.
Generally speaking, forged valve parts are made of materials with high strength and high temperature resistance, such as stainless steel, alloy steel, and even high-temperature alloys, which can maintain good performance at temperatures ranging from 500 ℃ to 1000 ℃ or even higher. These materials not only maintain structural stability at high temperatures, but also effectively resist oxidation and corrosion, thereby extending their service life.
The forging process itself can also enhance the high temperature resistance of materials, as forgings usually undergo strict heat treatment to ensure grain refinement and strength improvement of the metal at high temperatures. Overall, valve parts that have undergone forging and appropriate heat treatment can usually maintain good stability and performance at high temperatures, provided that the material selection and process are appropriate, and the design is correct to adapt to high-temperature working environments.
