These plates are renowned for their exceptional properties and versatility, making them a preferred choice for various industrial applications. In this comprehensive guide, we will explore everything you need to know about stainless steel 347 plates, including their properties, advantages, and applications.

What is 347 Stainless Steel Plates?

SS 347 plates are made from austenitic stainless steel that contains columbium (niobium) as a stabilizing element. This addition helps to enhance the material’s resistance to intergranular corrosion, which is a common issue in stainless steels exposed to high temperatures. The composition of 347 stainless steel typically includes 18-20% chromium, 9-13% nickel, and small amounts of carbon, manganese, phosphorus, sulfur, silicon, and columbium.
