Alloy steel flange
GlenFlange is a supplier of flanges in different types of material that we divide in: alloy steel, duplex/super duplex steel, nickel alloys/ Titanium and copper nickel alloys. We provide aluminum alloy flanges with the characteristics: These steels have greater strength, hardness, hot hardness, wear resistance, harden ability, or toughness compared to carbon steel. However, they may require heat treatment to achieve such properties. Common alloying elements are molybdenum, manganese, nickel, chromium, vanadium, silicon and boron.
Available forms are Alloy Steel Pipes & Tubes, Alloy Steel Round Bars, Alloy Steel Sheets & Plates, Alloy Steel Pipe Fittings, Alloy Steel Forged Fittings, Alloy Steel Fasteners, Alloy Steel Valves, Alloy Steel Flanges
