At our highly high-tech manufacturing unit, we have an excellent professional team who are holding desired skills, experience, and knowledge that make us able to fabricate high-quality Alloy 20 Flanges. Our Professionals are precisely managing and supervising the production process to produce damage-free products while maintaining proper quality standards. Because of higher weldability and formability, this increased range of flanges are well suited for various industrial applications. These Alloy 20 Flanges have prominent features such as flexibility, formability, longevity, ability to withstand heavy loads, and low maintenance. Also, Rajveer Stainless & Alloys manufactured flanges known for its high tensile strength, dimensional accuracy, ease to use, etc.
The Alloy 20 is also called carpentering 20. These excellent qualities of Alloy 20 Flanges contain nickel, chromium, and iron alloy that is developed for improved resistance to acidic environments. This Alloy 20 is a superalloy with excellent resistance to general corrosion, crevice corrosion, and pitting corrosion even in the chemical containing atmospheres such as nitric acids, phosphoric acids, and other harsh acids. These high qualities of Alloy 20 Flanges also include the niobium content that increases stabilization against sensitization and intergranular corrosion ability. These Alloy 20 is having an excellent combination with excellent corrosion resistance even with high mechanical properties.
We, Rajveer Stainless & Alloys, are using premium quality raw material for the fabrication of these high qualities of Flanges in a bulk amount. We, Rajveer Stainless & Alloys, always pay special attention to the quality production of the flanges. We are conducting destructive and non-destructive tests on the final product. And after that, only we are packaging these flanges with proper packaging material. And performs timely delivery of the product.
