Stainless Steel 348/348H Forged is an austenitic stainless steel alloy that boasts a high content of chromium and nickel, which gives it outstanding corrosion resistance and impressive mechanical strength. The “H” grade is specially stabilized with niobium, which boosts its resistance to sensitization at higher temperatures. This material shows remarkable creep and oxidation resistance, making it perfect for high-temperature applications. Typical mechanical properties include high tensile and yield strength, good ductility, and excellent toughness. This combination guarantees durability, stability, and dependable performance in both standard and challenging industrial settings.
