One of the well-known companies is Hex Forge Inc. We manufacture, supply, and ship the ASTM A182 SMO 254 RTJ Flange to our customers in India and around the world. We usually have a large stock of our products to serve our valued customers. Our SMO Flanges come in a variety of forms and sizes. This product is made to national and international standards of quality. Our manufactured goods are in high demand among our customers due to their features and long service life.

The SMO 254 RTJ Flange ensures granular corrosion resistance in all mineral acids. With a minimum tensile strength of 650 MPa, minimum yield strength of 300 MPa, and a 35 percent elongation rate, the A182 SMO 254 RTJ Flange outperforms standard stainless steel flanges. The alloy is widely utilized in high chloride-containing settings due to its high chromium, molybdenum, and nitrogen composition. Sulfide stress corrosion and chloride conditions are not a problem for our SMO Flanges. These flanges can be used in various industries, including thermal plants, heat exchangers, and the pharmaceutical industry. The melting point of the 6Mo RTJ Flange is around 1390 degrees C, and it has a density of 8 g/cm3. The SMO 254 RTJ Flange has pertinent Bolt holes in a round plate but no Center hole, so it can be used to close off the ends of pipe systems and pressure vessel openings.
