Alloy Steel Flanges
The Alloy steel flange is a kind of flange made of alloy steel material containing alloy elements such as chromium, molybdenum, nickel, etc. This kind of flange usually has the properties of high-temperature resistance, corrosion resistance, oxidation resistance, etc., which can be used in high-temperature, high pressure and corrosive pipelines.
