Rithav Pipes and Tubes, located in Delhi, India, has made a name for itself as a top-notch manufacturer and supplier of high-quality Stainless Steel 316H Seamless Pipes. These pipes are specifically designed to excel in high-temperature and high-pressure environments. The Stainless Steel 316H variant is a high-carbon version of 316, which means it boasts improved strength, creep resistance, and durability even under extreme conditions. Rithav adheres to international standards like ASTM A312, ensuring that their seamless pipes offer outstanding dimensional accuracy, corrosion resistance, and a smooth surface finish. These pipes are a go-to choice in industries such as power generation, oil & gas, petrochemicals, refineries, and chemical processing, where dependable performance is absolutely essential.
Stainless Steel 316H Seamless Pipes are made up of 16–18% chromium, 10–14% nickel, 2–3% molybdenum, and a higher carbon content (0.04–0.10%) to boost their strength at high temperatures. This extra carbon enhances both creep and tensile strength when things heat up. Their mechanical properties include a tensile strength ranging from 515–690 MPa, a yield strength of at least 205 MPa, an elongation of 35% or more, and a Brinell hardness of about 217 HB. These features ensure they perform excellently in thermal stress situations while resisting pitting, corrosion, and oxidation, especially in chloride-rich and acidic environments.
