Cast steel gate valve: it is a general term for all gate valves cast into castings with metal steel materials. Cast iron gate valve, forged steel gate valve and malleable cast iron gate valve corresponding to cast steel gate valve.
Cast steel gate valve: divided into carbon steel gate valve, stainless steel gate valve, low alloy steel gate valve (high temperature resistant chromium molybdenum steel belongs to this category), low temperature steel gate valve, etc.
There are also various specific steel grades under various cast steel gate valves, which are commonly used as follows:
1. The casting grades of carbon steel gate valves include: WCA, WCB, WCC, LCB, etc; Applicable temperature - 46 ℃ ~ 425 ℃.
2. Casting grades of stainless steel gate valves: 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 ℃ ~ 816 ℃.
3. Low alloy steel is divided into high-temperature alloy steel and high-strength low-alloy steel, among which high-temperature alloy steel is often called chromium molybdenum steel.
