Khaleed Stainless, a trusted manufacturer and supplier based in Riyadh, Saudi Arabia, is well-known for providing top-notch stainless steel products designed to cater to the diverse needs of various industries. One of their standout offerings, Stainless Steel 317 Nuts, is highly regarded for their remarkable corrosion resistance, durability, and strength. Thanks to a higher molybdenum content compared to standard stainless grades, these nuts offer superior protection against pitting, crevice corrosion, and chemical attacks. Crafted for secure fastening in challenging environments, Khaleed Stainless’s Stainless Steel 317 Nuts guarantee long-lasting performance, making them perfect for critical industrial and structural applications.
These nuts are primarily made up of iron, chromium (18–20%), nickel (11–15%), and molybdenum (3–4%), which greatly enhances their ability to withstand harsh chemical conditions. The alloy’s well-balanced composition provides excellent defense against chlorides, acids, and industrial solvents. On the mechanical side, they boast a tensile strength of around 515 MPa, a yield strength of 205 MPa, and an elongation of about 40%, ensuring they remain tough, stable, and reliable even in high-stress and corrosive situations. Their outstanding mechanical properties make them a go-to choice for fastening solutions in demanding industrial settings.
