Piyush Steel, a well-known manufacturer, supplier, and global exporter, provides stainless steel 347 sheets and plates that are highly resistant to corrosion and high temperatures. These sheets and plates are widely used in chemical processing, aerospace, power generation, and food processing industries due to their ability to withstand oxidation and intergranular corrosion.
Table Of Content
SS 347 is a stabilized austenitic stainless steel that has 17–19% chromium, 9–13% nickel, 2% manganese, and 0.08–0.10% carbon. It also has columbium (niobium), which makes it more resistant to carbide precipitation and sensitization. This makes it ideal for applications exposed to temperatures between 800°F and 1500°F (427°C - 815°C), where other stainless steels might be prone to corrosion and embrittlement.
These SS 347 sheets and plates offer a tensile strength of 515 MPa (75 ksi) and a yield strength of 205 MPa (30 ksi), ensuring strong structural integrity. With a Brinell hardness of 201 HB, they can manage demanding uses and resist wear. Furthermore, fitting for production in a range of sectors is the material's excellent formability and weldability.
Piyush Steel supplies SS 347 sheets and plates in different sizes to meet industry needs. They come in thicknesses from 0.5 mm to 100 mm and widths ranging from 1000 mm to 2500mm. Available in hot-rolled, cold-rolled, and custom-cut variations, they comply with ASTM A240, ASME SA240, and other international standards.
As a leading supplier based in Mumbai, India, Piyush Steel ensures that SS 347 sheets and plates meet strict quality standards for both domestic and global markets. Using these materials extensively in furnace components, high-temperature processing equipment, and structural applications, Piyush Steel guarantees dependability and long-lasting performance.
