GNEE steel is a standard exporter of Stainless Steel 304L Flat Bars, which are used in furnace retort seals, fans and fixtures. SS 304L Flat Bars is a nickel-chromium alloy with an addition of aluminum for outstanding resistance to oxidation and other forms of high temperature corrosion. Alloy 304L Flat Bars are quite resistance to carburization is good, and also resistant to carbon nitriding conditions. Grade 304L Flat Bars has good high temperature strength, and retains its ductility after long service exposure. Type 304L Flat Bars was designed for service temperatures from cryogenic to elevated temperatures in the range of 2000 Degree F.
