Hashmi Sheets and Plates is a trusted manufacturer and supplier of Stainless Steel 347 Foils in Doha, Qatar, serving industries that require stability, corrosion resistance, and reliable performance at elevated temperatures. We focus on supplying stainless steel products that meet international quality standards and perform consistently in demanding environments. Our Stainless Steel 347 Foils are carefully processed to ensure uniform thickness, smooth surface finish, and long service life. With timely delivery, technical support, and a customer-focused approach, Hashmi Sheets and Plates supports chemical, industrial, and fabrication projects across Qatar.
Stainless Steel 347 Foils are austenitic stainless steel alloys stabilized with niobium (columbium), which prevents carbide precipitation during welding or prolonged high-temperature exposure. This composition improves resistance to intergranular corrosion while maintaining good overall corrosion resistance. Mechanically, the material offers good tensile and yield strength, excellent toughness, and high ductility. It performs reliably across a wide temperature range and maintains structural stability in thin, heat-exposed applications.
