Champak Steel & Engg. Co is the leading manufacturer and supplier of the SS 321/321H Flanges. We make these flanges in various shapes and size as per the industrial requirements. In industries, flanges are used in a variety of equipment and thus are required in large quantity. We know the requirement of such industries, and so we make a different kind of flanges as per the necessity.
Flanges we produce follows the set industrial, national and international standards. Alloy 321H is a titanium settled austenitic alloy high in carbon content. This SS 321/321H Flange shows best corrosion resistance property. Also, this alloy is known for oxidation resistance up to 1500 F. In addition to this grade shows low-temperature toughness. Another impressive feature is intergranular corrosion resistance. High creep as well as stress rupture properties property of this grade make it suitable product.
Due to so many properties of SS 321/321H Flanges, they are mainly used in the aerospace application, storage and equipment in food processing, waste treatment plant, Chemical as well as petrochemical processing. Also, these are used in the gas processing, pharmaceutical, heat exchangers, condensers and pulp-paper industry.
Different types of flanges we produce are spectacle blind flange, SS socket weld flange, SS weld neck flange and SS ring joint flange. We also customise the SS 321/321H flanges in custom specifications. All the material we use are tested and impurity free. Product is individually tested and inspected by the inspection team. The product documentation, test certification and packaging are done.
Packing of the product is done in durable material like poly bags and wooden boxes. We ensure no scratch or damage is used to the product while shipping. Also, we make sure that the product is delivered on time. We, along with the product, offer some certificates and documents to the customers to ensure that the product we delivered is free from impurities and manufactured as per the industrial standards.
Our product can withstand high temperature environment of the industry and is long lasting, so it can be used in long term applications without any damage. You can get flanges of various grades here!
