Sahil Metals stands out as a reliable manufacturer and supplier based in Riyadh, Saudi Arabia, specializing in top-notch Stainless Steel 347H Square Bars and Rods. These products are crafted to offer exceptional strength, durability, and heat resistance. With a keen emphasis on precision and ensuring customer satisfaction, Sahil Metals guarantees that its offerings meet international standards, providing dependable performance across various industries. The Stainless Steel 347H Square Bars and Rods are renowned for their impressive resistance to intergranular corrosion, high-temperature strength, and extended service life, making them perfect for demanding applications in construction, petrochemical, and engineering fields.
These square bars and rods are austenitic stainless steels, featuring 17–20% chromium, 9–13% nickel, and niobium for stabilization, along with a higher carbon content than grade 347. This unique composition boosts creep strength and helps resist sensitization at elevated temperatures. They showcase tensile strength ranging from 550–750 MPa, solid yield strength, and remarkable toughness, even when faced with thermal stress. The combination of outstanding mechanical properties and corrosion resistance makes Stainless Steel 347H Square Bars and Rods ideal for critical high-temperature environments.
