Flanges
Alloy 20 Flanges are one of the most popular and highly demanded flanges in the market. Ranflex Metals has mastered the art of developing the best designs as per the standards while keeping in mind the requirements of the customers. The high demand for Alloy 20 flanges is due to its material properties as well as chemical and physical properties. Alloy 20 is an austenitic nickel-iron-chromium alloy. It offers maximum resistance to acids, especially sulfuric acid. It is highly resistant to corrosion, crevice corrosion and pitting corrosion in chemicals including sulfuric acid, chlorides, nitric acid and phosphoric acid. Its copper content protects it from sulfuric acid. Its high corrosion resistance also makes it useful in other industries such as power generation and the plastics industry. It also contains niobium, which helps stabilize it against sensitization and the associated intergranular corrosion. It is beautifully machined. Alloy 20 can be formed using conventional methods employing hot or cold working.
Ranflex Metals not only uses the finest raw materials for its manufacturing, but also employs highly automated and precise machinery operated by highly qualified and trained employees. Alloy 20 flanges, and other products undergo multiple quality inspections at every stage of production including heat treatment, welding, forging, etc. We do not compromise on the quality of our products. We ensure that the products manufactured by Ranflex Metals perform superiorly.
Our highly trained and skilled team has developed new designs and constructions that reduce the overall cost of Alloy 20 flanges making them affordable and easily available for purchase. We ensure proper packaging to prevent damage to the product both in the short term and in the long term. We are always ready to produce custom made products according to your requirements.
