Mcneil Instruments is a renowned manufacturer, supplier, and exporter in India specializing in AISI 347 welded tubes. These tubes are manufactured with elements colombium and tantalum to stabilize the alloy, known by its trade name UNS 34700. The Mcneil Instruments 347 Stainless Steel Tubing offers distinct advantages, particularly in high-temperature environments where temperatures fall within the chromium carbide precipitation range. This means that Mcneil Instruments Stainless Steel Type 347 Welded Tubing can effectively operate within a temperature range of 800°F to 1500°F. Furthermore, the mechanical properties of Mcneil Instruments Grade 347 Round Tubing, including creep and stress rupture properties, surpass those of grades 304 or 304L, making it a superior choice for various industrial applications.

As one of the premier manufacturers, suppliers, and exporters of 347 Stainless Steel Seamless Tubes in India, Mcneil Instruments offers top quality SA213 Tp347 Cres Tubing with a comprehensive Mill Test Report. Our tubing exhibits excellent resistance to oxidation-induced corrosion, particularly in high-temperature environments reaching up to 1500°F, potentially outperforming grade 321 stainless steel. Mcneil Instruments ensures competitive pricing for our 347 Seamless Tubing. Alongside standard tests such as hardness, flattening, tension, and flaring tests, each ASTM A213 Tp347 tube undergoes either a nondestructive electric test or a hydrostatic test. Engineered for applications in superheaters, steel boilers, and heat exchangers, our austenitic ASTM A213 Tp347 alloys guarantee superior performance and reliability.
