Renowned for its reliability, precision, and customer-focused service, the company supports industries like petrochemical, furnace, power generation, and heavy engineering with durable, heat-resistant stainless steel tubing designed for long-lasting stability and exceptional performance.
Stainless Steel 309H Tubing is crafted from a high-carbon version of the 309 alloy, which includes significant amounts of chromium and nickel, providing outstanding oxidation and corrosion resistance at high temperatures. The elevated carbon content boosts high-temperature strength and creep resistance. SS 309H tubing showcases impressive tensile and yield properties, good hardness, and stable mechanical performance even at temperatures exceeding 1000°C. The alloy retains toughness across a broad temperature range and offers excellent weldability and structural integrity. These characteristics make 309H tubing perfect for extreme heat environments and applications that demand long-lasting thermal stability.
