Duplex Steel Sheet, Plate and Coil Manufacturer, Supplier & Exporter in India

Stainless steel fittings are essential components in various industrial applications, renowned for their durability and resistance to corrosion. At RAGNAR METALS & TUBE, we offer a diverse range of stainless steel fittings, including grades such as 202, 304, 304L, 309, 310, 316, 317L, 321, 347, and 904L. These fittings are ideal for use in environments where high strength and corrosion resistance are required, making them suitable for industries such as oil and gas, food processing, and chemical manufacturing.

Our stainless steel fittings, particularly the 304 and 316 grades, are designed to withstand extreme temperatures and harsh conditions. Grade 304 stainless steel fittings are commonly used in food and beverage applications due to their hygienic properties, while 316 fittings are preferred in marine environments for their enhanced corrosion resistance. With additional grades like 317L and 321, we cater to specialized needs, ensuring that our clients have access to the right materials for their specific applications.

In addition to stainless steel, RAGNAR METALS & TUBE provides a variety of other materials including duplex steel (S31803, S32205), super duplex steel (S32750, S32760), nickel alloys (200, 201), and Inconel (600, 625, 718). Each of these materials offers unique properties that enhance the performance of our fittings in diverse industrial settings. For instance, duplex steel is known for its high strength and resistance to stress corrosion cracking, making it an excellent choice for challenging environments.

Our commitment to quality is reflected in our rigorous manufacturing processes, adhering to international standards such as ASTM A312, A213, and A269. With a size range from 1/2" NB to 24" NB for seamless fittings and up to 100" NB for welded fittings, we ensure that our products meet the demands of various industrial applications. Our fittings are available in multiple forms, including round, square, and rectangular, providing versatility for any project.

At RAGNAR METALS & TUBE, we understand the importance of reliable materials in industrial manufacturing.
