Stainless Steel 348H Bars are top-notch austenitic stainless steel products crafted for situations where outstanding corrosion resistance, high-temperature strength, and long-lasting durability are a must. The 348H grade is fortified with titanium, which boosts its resistance to intergranular corrosion. This makes these bars perfect for use in boilers, heat exchangers, pressure vessels, and power generation equipment that operate in high-temperature environments.
These bars are mainly made up of iron, chromium, nickel, and titanium. Chromium lends its corrosion-resistant properties, while nickel enhances toughness and ductility. Titanium plays a crucial role in stabilizing the structure, preventing sensitization when temperatures rise. With their impressive tensile strength, creep resistance, and thermal stability, these bars are ideal for applications that face prolonged exposure to high temperatures and stress.
