Aman Pipes and Tubes, a reputable manufacturer and supplier located in Hyderabad, India, specializes in high-quality Stainless Steel 347/347H Seamless Tubing, designed to withstand high temperatures and corrosive environments. SS 347 is a niobium-stabilized austenitic stainless steel that offers outstanding resistance to intergranular corrosion after welding. On the other hand, SS 347H, the high-carbon variant, is crafted for superior strength and creep resistance in elevated temperature settings. The seamless design guarantees leak-proof performance, consistent mechanical properties, and high pressure tolerance. Aman Pipes and Tubes is committed to precision manufacturing and timely delivery of tubing for applications in chemical plants, refineries, power generation, and high-performance industrial systems.
Stainless Steel 347/347H Seamless Tubing is composed of Chromium (17–19%), Nickel (9–13%), and Niobium/Tantalum (≥10xC) to prevent intergranular corrosion. SS 347H has a higher carbon content (0.04–0.10%) compared to SS 347 (≤0.08%), which enhances its creep strength. These tubes boast a tensile strength of around 515 MPa, yield strength of about 205 MPa, and approximately 35% elongation. The seamless construction ensures consistent wall thickness, excellent integrity under pressure, and resistance to high-temperature scaling. With great weldability, formability, and oxidation resistance, these tubes are a dependable choice for critical and long-term use in harsh environments.
