Khaleed Stainless is a well-known Riyadh-based manufacturer and supplier of stainless steel fasteners in Saudi Arabia catering to a host of industrial segments with top-class products. Among their top-tier products are Stainless Steel 347 Fasteners, which are characterized by outstanding resistance to high temperatures as well as intergranular corrosion. These fasteners are particularly ideal for repeated cycles of heating. With an emphasis on reliability, accuracy, and customer satisfaction, Khaleed Stainless is now a go-to choice for stainless steel solutions in Saudi Arabia as well as the Middle East.
Stainless Steel 347 Fasteners consist of iron, 17–19% chromium, 9–13% nickel, and columbium (niobium) stabilization for resistance to intergranular corrosion when welded or exposed to high temperatures. The grade offers superior resistance to oxidation as well as creep stress. The fasteners have a typical tensile strength of approximately 75 ksi, yield strength of 30 ksi, and elongation of approximately 40%. All these mechanical and chemical characteristics render the 347 fasteners apt for use in applications requiring both corrosion resistance and long-term structural integrity at elevated temperatures.

Featuring excellent resistance to oxidation and corrosion, Stainless Steel 347 screws come in sizes from M3 to M20, with lengths from 10mm to 150mm. They are suited for high-temperature and corrosive environments.
With superior corrosion and high-temperature resistance, Stainless Steel 347 washers are available in diameters ranging from M4 to M36. Thickness varies from 0.5mm to 5mm, making them suitable for various applications where durability is critical.
We always focuse on customer experience by way of our quality Stainless Steel 347 Fasteners. Every consignment comes attached with commercial invoices, packing lists, heat treatment charts, plans for quality assurance, and the NABL-approved lab test reports to establish genuineness and quality with client satisfaction.
Stainless Steel 347 Fasteners find extensive usage in high-temperature and corrosion-resistant environments like exhaust manifolds, heat exchangers, aerospace parts, and chemical processing apparatuses. Their columbium stabilization precludes carbide precipitation, rendering them perfect for service in cyclic exposure to elevated temperatures or welding. These fasteners are also used in refinery equipment and pressure vessels where creep and stress rupture resistance is necessary. Their resistance to heat, toughness, and ability to retain integrity under hostile conditions make them a reliable option in demanding industrial applications.
