Besides, this grade has the extension as the SS 321H Welded Tubing and this is the good austenitic steel material which is further known for its high carbon content. Both the grades are well-liked products for most of the manufacturing units like oil & gas plants, building & constructional fields, sugar-making units, general structuring works, nuclear & thermal power generating plants, and many more.
SS 321 Welded Tubing is a great alloy that offers high tensile as well as yield strengths and performing skills in the elevated temperate zones.
Also, the SS 321H Welded Tubing is the material with higher creep resisting strength and intergranular corrosion resistance and that too in the contact of chromium carbide precipitating temperate ranges. Even though, both grades are having splendid utility and longevity.
There are many custom designs available concerned with its sizes, shapes, dimensions, wall thickness levels, polishes, surface finishes, and others. This is the method with which we at Metinox Overseas are able to provide the client with the tubes as per their expectations.
They are accessible in the variety of end connections like different tube ends as plain, bevelled and threaded ends. Also, lengths like single or double random and the custom design and the pipe forms such as round tubes, square tubes, rectangular tubes, coiled tubes, āUā shaped tubes, pancake tubes, and hydraulic tubes.
We are performing some significant tests and inspections for authenticity and quality assurance of SS 321 Welded Tubing. Some of these tests are Spectro analysis, hardness tests, pitting resistance tests, Intergranular Corrosion resistance (IGC) tests, and so on.
