Nizar Sheetsandplates, a reputable manufacturer and supplier located in Amman, Jordan, specializes in top-notch Stainless Steel 348H Angles designed for outstanding performance in high-temperature and corrosive settings. This high-carbon variant of grade 348 is stabilized with niobium and tantalum, giving it remarkable resistance to intergranular corrosion, making it perfect for applications that involve continuous heat exposure. Nizar Sheetsandplates guarantees precise dimensions, consistent strength, and a polished finish across all their angles. With cutting-edge production capabilities and rigorous quality standards, the company provides dependable, long-lasting angles that are ideal for critical industrial and structural uses.
Stainless Steel 348H Angles are composed of 17–19% chromium and 9–12% nickel, with stabilization from niobium and tantalum to inhibit carbide formation at high temperatures. The high-carbon content enhances strength, creep resistance, and stress-rupture performance during extended heat exposure. Mechanically, this alloy boasts high tensile and yield strength, good toughness, and excellent corrosion resistance in oxidizing environments. SS 348H retains its structural integrity during welding and forming processes and excels under thermal cycling, making it a great choice for demanding applications that require durability and stability at high temperatures.
