Stainless steel 321/ 321H is an austenitic stainless steel alloy stabilized by the addition of titanium. This grade is widely used in industrial applications because it is non-sensitive to the intergranular corrosion after it gets heated within the precipitation range of up to 425-850 degree Celsius. This stainless steel grade has become an ideal choice for numerous applications due to its features and properties. However, if we talk about SS 321 / 321H Pipe Tube, they are one of the most demanding and popular stainless steel products used worldwide.

Stainless steel 321 and 321H grade offers high strength and resistance to scaling features which makes pipes and tubes suitable for high-temperature services. Nextgen steel & alloys are one of the reputed and renowned manufacturers of these SS 321 and 321H pipes tubes. We at the time of manufacturing these tubes and pipes use superior quality of raw material as per the international quality standards. In addition to it, the latest machines and tools are used for manufacturing these products. Each and every material we use for manufacturing purpose is inspected before it gets delivered for the manufacturing process.

Other details-
To check whether the manufactured product is of high quality or not, there are several inspections and quality analysis done. The entire inspection process takes place under the supervision of experts as per the set industrial rules and norms. The tests include pitting resistance test, positive material identification or PMI test, flaring test, flattening test, radiography test and more. When all the tests and inspections are completed, the SS 321 / 321H Pipe Tube is packed in the superior quality of packaging material with labeling and delivered to their respective customers.
