- Stainless Steel 316 Seamless Tube
Neeka Tubes is a reliable supplier and exporter of Stainless Steel 316 Seamless Tubes that are made to meet all of the requirements set by ASTM A312 TP316, ASTM A269 and ASME. Our SS 316 seamless tubing is known for its resistance to corrosion, high tensile strength, and long operational life. It is the best choice for important industries like chemical processing, petrochemicals, oil and gas, power generation, pharmaceuticals, food and drink and marine engineering.
Stainless Steel 316 Seamless Tubes are made with molybdenum, which makes them more resistant to corrosion, pitting and crevice damage caused by chloride. This makes them more reliable than regular 304 stainless steel Pipes. We offer Stainless Steel 316L Seamless Tubes, a low-carbon type that is widely used in process industries, sanitary applications, and offshore environments. Our tubes are better at welding and don’t let carbide precipitation happen as easily.
