Introduction

If your application involves elevated temperatures, aggressive chemical environments, or extensive welding, Stainless Steel UNS S34700 Sheets & Plates are one of the most dependable material choices. Grade 347 stainless steel is a stabilized chromium-nickel alloy containing niobium (columbium), which improves resistance to carbide precipitation during welding and prolonged exposure to high temperatures.

As a trusted Stainless Steel Sheets & Plates Supplier, we provide premium-quality products manufactured according to international standards. Our range includes hot rolled, cold rolled, polished, and custom-cut plates that meet demanding industrial requirements.

Whether you require a reliable 347 stainless steel plate manufacturer for industrial projects or are searching for experienced 347 stainless steel sheet suppliers, we deliver products that combine excellent quality, dimensional accuracy, and dependable performance.

What are Stainless Steel UNS S34700 Sheets & Plates?

Stainless Steel UNS S34700 Sheets & Plates are flat-rolled stainless steel products manufactured from stabilized Grade 347 alloy. The addition of niobium helps prevent chromium carbide formation during welding, preserving corrosion resistance even after exposure to temperatures between approximately 425°C and 850°C.

Compared with conventional Grade 304 stainless steel, Grade 347 offers improved resistance to intergranular corrosion and performs exceptionally well in high-temperature service.

These SS Sheets & Plates are widely used where strength, oxidation resistance, and long service life are essential.
