Stainless Steel 347 Plates Supplier

 347H Stainless Steel plate is an austenitic stainless steel with a face centered cubic structure that can be used for a variety of applications. In its annealed state, it is non-magnetic and can only be toughened by cold working. Niobium has been added to prevent chromium carbide precipitation at the grain boundary. 347H plate has higher carbon content than 347 plates. 347H plate is tougher and more durable than 347 plates because of the extra carbon content.

These SS 347 and 347H Plates are also used to make boiler tubes and casing, radiant super heaters, high-pressure steam pipes, heat exchangers, and tubes. Cabin heaters, heavy wall welded equipment, and the aerospace sector are all examples of applications for this grade of stainless steel. Aircraft exhaust stacks and collection rings are another application where these Stainless Steel plate grades come in handy. Alloy 347 stainless steel plate has general corrosion protection that is similar to that of 304 stainless steel plate. It was created for usage in the chromium carbide precipitation range of 800 to 1500 ° F, where unreinforced alloys like 304 are vulnerable to intergranular assault. In this temperature range, Alloy 347 stainless steel plate outperforms Alloy 321 stainless steel plate in terms of total corrosion resistance. In heavily oxidizing situations up to 1500 ° F, Alloy 347 operates significantly better than Alloy 321.
