Al Shakru Sheets and Plates, based in Dubai, UAE, distinguishes itself as a leading manufacturer and supplier of Stainless Steel 347H Sheets and Plates . These products are renowned for their outstanding high-temperature strength, exceptional corrosion resistance, and lasting durability. Made from austenitic stainless steel stabilized with niobium, these sheets and plates successfully guard against carbide precipitation, allowing them to deliver excellent performance in high-temperature environments. At Al Shakru Sheets and Plates, precise manufacturing is paired with strict quality control, producing 347H sheets and plates that meet international standards. They’re ideal for numerous applications across industries such as chemical processing, power generation, and beyond, providing lasting structural integrity, reliable performance, and resistance to scaling and oxidation even under the harshest conditions.
Stainless Steel 347H Sheets and Plates are made up of chromium (17–19%), nickel (9–13%), and niobium, an addition that enhances their resistance to intergranular corrosion while preserving strength at elevated temperatures. They deliver a tensile strength of roughly 515 MPa, a yield strength of 205 MPa, and an elongation of 40%. Featuring a density of 8.0 g/cm³ and a melting range of 1390–1425°C, these sheets and plates are recognized for their outstanding toughness, weldability, and formability, even under high-temperature and corrosive conditions.
