Cast steel gate valve: It is all gate valves that are cast into castings made of metal steel materials, collectively called cast steel gate valves. Corresponding to the cast steel gate valve, it also has a cast iron gate valve, a forged steel gate valve, and a malleable cast iron gate valve.

 

  classification:

 

  Cast steel gate valve: According to the material, there are carbon steel gate valve, stainless steel gate valve, low alloy steel gate valve (high temperature resistant chrome molybdenum steel belongs to this category), low temperature steel gate valve and so on.

 

  Various types of steel grades under various cast steel gate valves are commonly used as follows:

 

  1. Carbon steel gate valve casting grades are: WCA, WCB, WCC, LCB, etc.; applicable temperature -46 degrees ~ 425 degrees.

 

  2, stainless steel gate valve casting grade: 301 stainless steel, CF8 stainless steel (corresponding to forging 304 stainless steel), CF8M stainless steel (corresponding to forging 316 stainless steel), etc.; applicable temperature -198 degrees ~ 816 degrees.

 

  3. Low-alloy steel is divided into high-temperature alloy steel and high-strength low-alloy steel. Among them, high-temperature alloy steel is commonly known as chrome-molybdenum steel.

 

  Casting grades of chrome-molybdenum steel gate valves: ZG1Cr5Mo, ZG15Cr1MoV, ZG20CrMoV, WC6, WC9, C12A, etc. Applicable temperature 550 degrees to 750 degrees.

 

  The temperature applicable to each specific grade material varies, depending on the actual operating conditions.
