We at Gayatri Tubes are suppliers, manufacturers, exporters and wholesalers of SS 321 / 321H Sheet Plate / Structurals in India and overseas. We manufacture stainless steel plates and sheets and customized them using high-quality raw material. Furthermore, we offer plates and sheets of different sizes and dimensions. The Austenitic Stainless Steel 321 / 321H Sheet Plate / Structurals is titanium stabilized and offers excellent corrosion resistance. Moreover, it has intergranular corrosion, and it is very good at resisting the oxidation to stress ruptures and high creeps. Furthermore, it poses excellent low-temperature toughness. Apart from this, no heat treatment can harden the steel plate as it can only be done by cold working. Furthermore, it can be easily processed and welded by a fabrication process. It exhibits excellent corrosion resistance and can work best with diluted organic acids. Moreover, it offers high tensile strength and precise design.
Apart from this, we as a manufacturer uses stainless steel for creating military equipment, ships, aerospace, paper industry, etc. In many power generation and gas processing industries, Stainless Steel 321 / 321H Sheet, Plate / Structurals is used. Besides this, we even provide material testing services so that the customer would be sure about the quality and its contents. The testing further includes the flattening test, hardness test, chemical analysis, etc. More tests like radiography, flaring, flattening, ultrasonic, and more are done. In terms of documentation, we provide legalized certification and the raw material test reports. Moreover, there will be a guarantee letter with the product you receive. We also provide packaging services in which we package the product according to customer requirements. Besides this, shipping details will mention on the package.
The SS 321 / 321H Sheet Plate / Structurals is very ductile, and as a result, it can take any form easily. Moreover, it has a machinability of Type 304 and offers excellent corrosion resistance at the same time. We provide stainless made of standard process. It has all the chemical composition that is required to produce quality stainless steel. Furthermore, it has a high carbon level, as well. It further offers cold and hot forming along with machining.
