Khaleed Stainless stands out as a top manufacturer and supplier of Stainless Steel 347H Tubing in Riyadh, Saudi Arabia. They provide high-quality tubing solutions that are built to last, resist corrosion, and perform exceptionally well in high-temperature settings. Crafted using cutting-edge technology and adhering to strict quality standards, these tubes are well-known for their impressive resistance to intergranular corrosion and outstanding creep strength. Stainless Steel 347H Tubing finds extensive use in industries like petrochemical, power generation, oil and gas, and pharmaceuticals, where heat resistance and long-term stability are essential. Khaleed Stainless is committed to delivering consistent quality, durability, and reliability, making these tubes perfect for critical industrial applications.
The composition of Stainless Steel 347H Tubing includes chromium, nickel, and carbon, along with niobium stabilization, which boosts its resistance to intergranular corrosion and enhances weldability. With a higher carbon content than standard 347, it offers improved high-temperature strength and creep resistance. The tubing boasts a tensile strength between 520–750 MPa, along with high yield strength and good elongation, ensuring it remains tough and ductile even under challenging conditions. Niobium stabilization helps reduce carbide precipitation during welding and heat treatment, allowing the tubing to maintain its structural integrity and performance in elevated temperature environments.
