Stainless Steel 347/347H Pipes & Tubes from Steel Icon Stainless Pvt. Ltd. are engineered to meet the demanding requirements of modern industrial, mechanical, and structural systems. These high-performance stainless steel products are widely used in environments where elevated temperature resistance, corrosion protection, and long service life are critical. Industries such as chemical processing, power generation, petrochemicals, refineries, and pressure equipment manufacturing rely on stabilized stainless steel pipe and tube solutions to maintain reliability and operational safety.
Manufactured using advanced metallurgical processes and strict quality control procedures, Stainless Steel 347/347H Pipes & Tubes offer excellent resistance to intergranular corrosion and maintain mechanical stability even in high-temperature service conditions. Their balanced chemical composition and enhanced structural integrity make them a preferred choice for heat exchangers, boilers, pipelines, and industrial fabrication projects that demand dependable performance.
Stainless Steel 347 and 347H are stabilized austenitic stainless steel grades that contain chromium, nickel, and niobium. The addition of niobium plays a critical role in stabilizing the alloy against chromium carbide precipitation, which significantly improves resistance to intergranular corrosion during welding and prolonged exposure to high temperatures. Stainless Steel 347H is a higher carbon variant of grade 347, specifically designed to provide improved creep resistance and enhanced strength at elevated temperatures.
These stainless steel pipes and tubes are known for their excellent oxidation resistance, superior toughness, and high thermal stability. Their austenitic microstructure ensures strong resistance to corrosion in acidic and oxidizing environments commonly found in chemical processing plants and refinery systems. The material also provides good formability and weldability, allowing engineers and fabricators to produce complex industrial components while maintaining structural reliability.

Stainless Steel 347/347H Pipes & Tubes provide several performance advantages that make them suitable for heavy industrial use. Their high chromium and nickel content delivers excellent corrosion resistance in aggressive environments, including exposure to chemicals, high moisture levels, and industrial pollutants. The niobium stabilization prevents carbide precipitation during welding, which preserves the corrosion resistance of the material even after fabrication.
Another major benefit is the ability of Stainless Steel 347H to maintain mechanical strength at elevated temperatures. This makes the material particularly suitable for boilers, heat exchangers, and pressure vessels used in thermal processing industries. These pipes and tubes also offer good machinability and fabrication flexibility, allowing manufacturers to produce seamless and welded components with precision.
Long-term durability is another defining advantage. Stainless Steel 347/347H pipes and tubes resist scaling, oxidation, and structural degradation under continuous thermal stress. As a result, industries benefit from reduced maintenance costs, extended service life, and improved operational efficiency in demanding environments such as power plants and refinery pipelines.
