What Are The Commonly Used Forged Steel Materials For Forged Steel Gate Valves? How To Choose According To The Properties Of The Medium And The Working Environment

Common forged steel materials for forged steel gate valves include:

1. A105 (ASTM standard): A105 is a common carbon steel material with good mechanical properties and welding properties, suitable for the manufacture of forged steel gate valves for general industrial applications.

2. LF2 (ASTM standard): LF2 is a type of low-temperature carbon steel, usually used for forged steel gate valves under low-temperature conditions, with good low-temperature toughness and corrosion resistance.

3. F11 (ASTM standard): F11 is a chromium-molybdenum alloy steel, usually used for forged steel gate valves under medium temperature and pressure, with good corrosion resistance and mechanical properties.

4. F22 (ASTM standard): F22 is a chromium-molybdenum alloy steel, which has higher oxidation resistance and high temperature resistance than F11, and is suitable for forged steel gate valves under high temperature and high pressure conditions.

5. F304/F316 (ASTM standard): F304 and F316 are chromium-nickel alloy steels of stainless steel 304 and 316, respectively, with excellent corrosion resistance, suitable for forged steel gate valves for corrosive media.

6. F51/F53/F55 (ASTM standard): These are duplex stainless steel materials with high corrosion resistance and mechanical properties, suitable for forged steel gate valves in harsh working conditions such as marine environments.

When selecting the material of a forged steel gate valve, factors such as the nature of the medium, temperature, pressure, and working environment need to be considered. General selection principles include:

1. Medium properties: Select materials with corresponding corrosion resistance, such as carbon steel, stainless steel, or alloy steel, according to the corrosiveness, temperature, pressure, and other characteristics of the medium.

2. Temperature and pressure: When selecting materials, consider their tolerance at given temperatures and pressures to ensure that the forged steel gate valve will not fail or deform under working conditions.

3. Working environment: Considering the special requirements of the working environment, such as low temperature, high temperature, high pressure, corrosive environment, marine environment, etc., select materials with corresponding properties.

4. Cost and availability: Consider the cost and availability of the material, and select economical and practical materials to meet engineering needs.

Considering the above factors comprehensively, you can choose Forged Steel Gate Valve material that suits specific engineering needs.
