Khaleed Stainless is a well-respected manufacturer and supplier of high-quality stainless steel fasteners located in Riyadh, Saudi Arabia. The company has built a strong reputation for its dedication to quality, innovation, and customer satisfaction. They specialize in producing durable and corrosion-resistant products, such as Stainless Steel 405 Nuts. These nuts are designed to perform reliably in high-temperature and moderately corrosive settings, making them perfect for demanding industrial applications. With state-of-the-art manufacturing facilities and a talented technical team, Khaleed Stainless caters to various industries, including petrochemical, power generation, and oil & gas throughout Saudi Arabia and the broader Middle East.
Stainless Steel 405 Nuts are primarily made up of iron and chromium (11.5–14.5%), along with small amounts of aluminum, carbon, manganese, silicon, phosphorus, and sulfur. The inclusion of aluminum helps enhance the grain structure and boosts oxidation resistance. These nuts provide moderate corrosion resistance and excel in high-temperature conditions. They have a tensile strength of about 380–550 MPa and a yield strength of around 205 MPa. While they can’t be hardened through heat treatment, SS 405 nuts are magnetic, easy to machine, and thermally stable, making them perfect for situations where thermal cycling and oxidation resistance are essential.

Khaleed Stainless is providing the quality material using rigorous testing procedure. All products, including 405 Stainless Steel Nuts, are tested as per hardness by chemical analysis as per spectroanalysis, PMI testing, tensile testing micro and macrostructural tests, and pitting as well as IGC testing. These checks ensure superior performance from our materials. Along with our commitment towards quality, we provide all relevant documents such as commercial invoices, packaging lists having net and gross weights, box numbers, labels, and a Certificate of Origin legalized or attested by the Chamber of Commerce or Embassy. Our Third-Party Inspection Certificate also ensures that our customers have complete satisfaction over the price as well as the delivery of Stainless Steel 405 Nuts.
Stainless Steel 405 Nuts find their place in high-temperature and moderately corrosive environments. They’re perfect for fastening applications in heat exchangers, exhaust systems, steam turbines, and furnace assemblies. Thanks to their thermal stability and resistance to oxidation, these nuts are also utilized in power plants, petrochemical facilities, and refineries. Their ferritic structure minimizes distortion during thermal expansion and contraction cycles. Cost-effective and dependable, SS 405 nuts are an excellent choice for industrial applications.
