    Detailed Information

    Supplier & Manufacturer of Stainless Steel 347/347H Seamless Tubes

    SS 347 and SS 347H both are types of austenitic stainless steel. They both are almost similar to each other, the only difference is in the carbon content. SS 347H Seamless Tubing contains more carbon than SS 347. They are such amazing alloys that their addition to different industrial products provides some advantageous properties. Properties like fantastic resistance in a strongly oxidizing environment, a good resistance to corrosion, also have a resistance over intergranular corrosion even at higher temperature ranges of approximately 427-816 degrees Celsius. 

    In this, by the addition of columbium, the alloy is stabilized. Moreover, the corrosion resistance of SS 347 is greater in comparison to SS 321. This material at high temperatures provides good mechanical properties. There are different benefits of using them in the industries for various applications that include resistance to corrosion, sustainability at high temperature, good resistance towards intergranular corrosion, and strong resistance towards higher oxidizing environments. They can also be used in fields where some mild acids and diluted acids are used or formed as this offers resistance to damage from certain acids.

    It can be used in wide applications and industries like dairy processing, chemical industries, petrochemical industries, pulp and paper industries, oil and gas industries, water processing, offshore and onshore applications, fertilizer industries, power plants, wastewater treatment plants, and many more. SS 347 Cold Drawn Tubes has some special properties such as it has excellent resistance to high-temperature corrosion, also has excellent processing characteristics, and others. We offer various types of SS 347 / 347H Seamless Tubing such as Round Tubes, Heat Exchanger Tubes, Hydraulic Tubes, Coiled Tubes, Cold Drawn Tubes, Welded Tubes, Square Tubes, Rectangular Tubes, Decorative Tubes, Sanitary Tubes, Polish Tubes, Instrumentation Tubes, Bright Annealing Tubes, and many more. We also supply general grades such as Stainless Steel Cold Drawn 347H Tubes in standard tube sizes and wall thicknesses. Our Stainless Steel 347 Seamless Tubes are tested and examined by industrial experts to ensure high standard quality, creek, or damages before supplying them to our clients. We perform a number of tests on our SS 347H Seamless Tube to ensure high standard quality. The tests conducted Pitting Resistance Test, PMI Testing, IGC test, Chemical Test, Mechanical Test, Hardness Test, Flattening Test, Flaring Test, Micro Test & Macro Test, Tensile Test, etc. Some of the other tests are chemical analysis, eddy current testing, hydrostatic testing or ultrasonic examination, NDT, and also chemical and physical property inspection, Rockwell hardness test, chemical test, intergranular corrosion test, positive material test, flattening test, flaring test, and third-party inspection, and so on.

    ASTM A213 TP 347 Stainless Steel Seamless Tubes should be well-thought-out for appliances that require discontinuous heating between the range of 427 Deg Celsius to 899 Deg Celsius, or for welding under conditions that put off a post-weld anneal. These Stainless Steel ASTM A269 TP 347 Seamless Tubes are non-magnetic, where the high temperature creep strength and stress rupture is superior to SS 304. Meanwhile, the room temperature yield potency and tensile power of ASTM A213 TP SS 347 Seamless Tubes are more or less 35,000 psi and 85,000 psi, correspondingly. SS 347 Seamless Tubing is made up of a special type of stainless steel where it is hardened by using precipitation techniques. Stainless steel tubes are more special in comparison to the other ones as it offers excellent corrosion resistance. The grade SS 347H Seamless Tubing is tougher than 347 ones because of the presence of more carbon content in it.
