Hastelloy C276 is a popular alloy for fabricating flanges. Ratna Exports is one of the largest suppliers and stockists of superior quality Hastelloy C276 Flanges worldwide. We manufacture flanges of all types, grades, sizes, and dimensions.
Hastelloy C276 Flanges are made of high quality that has high flexibility, tensile strength, toughness, and corrosion resistance. It is an alloy augmented with tungsten that offers excellent corrosion and oxidation resistance. These flanges are highly resistant to pitting, crevice corrosion, stress corrosion cracking, and abrasion in any severe atmosphere.
Also, Hastelloy C276 Flanges are considered robust under high pressure and high temperatures due to excellent toughness and tensile strength.
The flanges’ excellent formability, welding capabilities, workability, and fabricability characteristics make them ideal for many industrial applications. These include petrochemical, pharmaceutical, pulp, paper, and many others that are not restricted to one application.
Our manufacturing unit at Ratna Exports is fully equipped with advanced machinery, tools, and machinery to fabricate Hastelloy C276 Flanges. Our company has a large stock of these flanges so that we can deliver them quickly. Our professionals and workers work diligently to fabricate excellent quality flanges that meet the exact requirements of our esteemed clients. For fabrication, we use innovative methods and equipment.
We supply Hastelloy C276 Flanges to the global industrial market at affordable prices. These flanges are designed for high creep-rupture and stress-rupture resistance. Our expert team is supervised to achieve the efficiency of manufacturing flanges by international quality standards. The highest quality raw materials are used in manufacturing to ensure high performance and low maintenance.
We manufacture Hastelloy C276 Flanges in standard and custom-made specifications to satisfy our valued clients. Our quality experts conduct many quality checks on every flange they manufacture so that quality and performance remain the same. Several of these tests include both destructive and non-destructive inspections where our experts test various attributes of flanges. Testing each flange is paramount to us before handing it over to the customer. Packaging is only performed on defect-free and dimensionally accurate Hastelloy C276 Flanges. Our packaging materials are adequate to avoid damage during delivery. Our service ensures that the flanges are delivered to the specified locations of worldwide customers on time and within the specified timeframe.
