Khaleed Stainless is a reputable manufacturer and supplier based in Riyadh, Saudi Arabia, known for its top-notch Stainless Steel 347H Fasteners. These fasteners are designed to offer exceptional strength, durability, and resistance, making them perfect for tough industrial applications. You’ll find them commonly used in sectors like petrochemical, oil and gas, power generation, and chemical processing, where high-temperature stability and corrosion resistance are absolutely vital. Crafted to meet international quality standards, Khaleed Stainless’s Stainless Steel 347H Fasteners guarantee dependable connections, leak-proof performance, and a long lifespan in critical piping, structural, and machinery setups.
These fasteners are primarily made up of iron, chromium (17–19%), nickel (9–13%), and niobium (columbium), featuring a higher carbon content than the standard 347. The inclusion of niobium helps stabilize the alloy, preventing carbide precipitation and boosting resistance to intergranular corrosion, especially during welding and high-temperature use. On the mechanical side, these fasteners boast a tensile strength of around 515–550 MPa, a yield strength of 205–240 MPa, and impressive elongation, which together provide toughness, thermal stability, and reliable performance even under stress and elevated temperatures.
