Crafted with precision and in line with international standards, these tubes are well-regarded for their ability to resist intergranular corrosion, along with their strength and stability at elevated temperatures. Stainless Steel 348H Tubing finds extensive use in industries like petrochemical, power generation, pharmaceuticals, and aerospace, where heat resistance and corrosion protection are absolutely vital. Khaleed Stainless guarantees a long service life, exceptional quality, and reliable performance, making these tubes a dependable choice for even the most demanding applications.
The composition of Stainless Steel 348H Tubing includes chromium, nickel, and is stabilized with niobium and tantalum, featuring a higher carbon content compared to standard grades. This unique blend provides impressive tensile strength ranging from 520–750 MPa, along with high yield strength and good elongation, ensuring both toughness and ductility. The increased carbon content boosts creep resistance, making it ideal for prolonged use at elevated temperatures. The stabilization with niobium and tantalum helps to reduce carbide precipitation during welding, which enhances resistance to intergranular corrosion while maintaining excellent mechanical stability in high-temperature settings.
