Stainless Steel 304L Flanges Manufacturer

SS S30403 Flanges, SS 1.4306 / 1.4307 Socket weld Flanges, Stainless Steel 304L Flanges, 304L SS Slip on Flanges, ANSI B16.5 Stainless Steel 304L Flanges, ASTM A182 F304L SS Weld Neck Flanges, SS 304L Flanges Suppliers in Mumbai, India.

Astec Tubes is the manufacturer, supplier, traders and exporter of the excellent quality of SS 304L Flanges to the global clients. Our offered flanges are molybdenum-bearing and low carbon contended austenitic steel material that is having very good corrosion resistance properties. The low carbon in SS slip-on flanges is providing very good sensitization resistance ability at the time of welding and several thermal techniques. SS threaded flanges are non-magnetic in nature in the annealed condition but it becomes a little bit magnetic resulting from the welding. SS weld neck flanges are having very good resistance to general corrosion in different ranges of chemical especially into the acidic chloride atmosphere like those that are suspected into the pulp & paper industry.

SS blind flanges are having very good resistance ability of the sulphuric acid concentration to 5% at the temperature higher as 120 deg F and under 100 deg F. SS Socketweld flanges are having very good resistance ability to the greater concentration. SS lap joint flanges are having little bit enhanced resistance to corrosion over the several materials into the strongly oxidizing atmosphere, resulting from the tantalum and columbium addition. SS ring joint type flanges don’t perform better into the chloride solutions and also into the tiny concentrations. SS spectacle blind flanges machinability is quite tough and thus it is work-hardened through the machining.
