Alpha Overseas(AOS) manufactures and exports these SS 347 Sheet Plate / Structural, which are beneficial in applications that need omission of the annealing procedure after welding. Stainless Steel 347 Plates should be considered for applications requiring intermittent heating between 800 Degree F (427 Degree C) and 1650 Degree F (899 Degree C), or for welding under conditions which prevent a post-weld anneal. Stainless Steel 347 Structural is columbium stabilized austenitic stainless steel plate with good general corrosion resistance and somewhat better resistance in strong oxidizing conditions than 321. SS 347 Plates is frequently used for the fabrication of equipment, which must be placed in service under severe corrosive conditions, and is also common to the petroleum refining industries. SS 347 Structural can be welded using most of the resistance and fusion methods, where oxyacetylene welding is not preferred for this steel. The use of slow speeds and constant positive feeds will minimize this tendency of 347 Stainless Steel Plates to work harden.

Stainless Steel 347 Sheets Plates Manufacturing, SS DIN 1.4541 Chequered Plates Suppliers, ASTM A240 SS Shim Plates Manufacturer, Stainless Steel 347 Plates, SS 347 Sheets, Stainless Steel 347 Plates Suppliers, Sheets Manufacturer & Stockist in Mumbai, India.

Stainless Steel 347 Coils offer higher creep and stress rupture properties than Type 304 and, particularly, Type 304L which might also be considered for exposures where sensitization and intergranular corrosion are concerns. 347 Stainless Steel Structural maintains good corrosion resistance in applications where the temperature is between 800 Degree F and 1500 Degree F.

Typical applications of 347 Stainless Steel Sheets include stainless steel piping, gas turbine and boiler in steam generation and power plant industries.
