What Impact Does The Material Selection And Seat Material Of Forged Steel Globe Valves Have On Their Performance And Corrosion Resistance

The material selection and valve seat material of Forged Steel Globe Valve have an important influence on its performance and corrosion resistance. The choice of different materials depends on factors such as the nature of the medium, temperature, pressure and flow rate. The following are some common forged steel stop valve material selection and the influence of valve seat material on performance and corrosion resistance:

1. Forged steel material selection for forged steel stop valve:

- Carbon steel (A105): Commonly used in general working conditions, with good mechanical properties and strength, suitable for medium at room temperature.

- Stainless steel (such as 304, 316): Has good corrosion resistance, suitable for corrosive media or working conditions under high temperature and high pressure conditions.

- Alloy steel: Has good wear and corrosion resistance, suitable for working conditions under high temperature and high pressure conditions.

- Other special alloy steels: such as chrome-molybdenum steel, chrome-molybdenum-molybdenum steel, etc., have higher corrosion resistance and mechanical properties, suitable for extreme working conditions.

2. Forged steel stop valve seat material selection:

- Stainless steel (such as 304, 316): Suitable for general corrosive media, with good corrosion resistance and sealing.

- Polytetrafluoroethylene (PTFE): Suitable for media with high sealing requirements, with good corrosion resistance and wear resistance.

- Hard alloy: Suitable for working conditions under high temperature and high pressure, with good wear resistance and corrosion resistance.

Forged steel stop valves choose suitable materials according to the properties of the medium:

- Corrosive media: Choose corrosion-resistant materials, such as stainless steel or special alloy steel.

- High temperature and high pressure media: Choose materials that are resistant to high temperature and high pressure, such as alloy steel or hard alloy.

- Medium with high sealing requirements: Choose materials with good sealing performance, such as PTFE.

When selecting materials, it is necessary to comprehensively consider the properties of the medium, working conditions and safety requirements, and select suitable forged steel stop valve materials and valve seat materials according to actual conditions to ensure the performance and corrosion resistance of the valve.
