Gautam tubes are a professional producer and supplier of Stainless Steel 321H Flanges. We provide complete solutions of industrial flanges for chemical processing industries. In our multi base manufacturing facility, we are able to flanges in bulk quantities. Here we produce other ferrous and nonferrous flanges for varying industrial demands. We use only high quality materials for processing flanges that attain desired properties after finishing. Some properties are heat resistance, corrosion resistance, strength, toughness, etc.SS flanges are highly engineered to apply in industrial demanding and critical applications.
SS 321H is a higher carbon version of the flanges. These flanges are designed to enhance creep resistance and for higher strength at higher temperatures above 1000 deg F. in most cases, the carbon content of the flanges enables dual certifications. However, these flanges cannot be hardened by heat treatment operations, only cold working is considered.
SS 321H display good local and general corrosion resistance in 300 series. It is used for utilizing in chromium carbide precipitation range 1800 deg F to 1500 deg F; here other un-stabilized alloys may be subjected to intergranular corrosions. Importantly, SS 321 H can use in most dilute and concentric organic compounds at moderate to higher temperatures such as hot or pure phosphoric acids. In the hydrocarbon containing environments, it opposes acid stress corrosion cracking.

Moreover, these flanges can be utilized in fluoride and chloride free caustic solutions at nominal temperatures. However, SS flanges cannot perform well in chloride solutions even in small concentrations. For work hardening, slow speeds and heavy feeds, it reduces alloy tendency. Promptly, Stainless steel 321H Flanges are welded by all welding operations such as arc welding or resistance welding.
In addition to titanium, flanges oppose carbide precipitation range during welding. The hot working temperature is between 2100 deg F to 2300 deg F. above 1700 deg F exposure of these flanges are not alloyed. SS flanges are quenched or completely annealed after working to attain higher levels of corrosion resistance. Stainless steel 321H Flanges are annealed in temperature between 1800 deg F to 2000 deg F.
