Manufacture of ASME SA182 Grade 304 SS SORF/ BLRF/ WNRF Flanges for industrial use
astm a182 f304 flanges are made up of the basic austenitic stainless steel grade. These flanges belong to ASTM A182 specification for high temperature, high pressure applications. Viha Steel & Forging is a leading manufacturer and supplier of the different types of the aisi 304 flanges in various sizes and dimensions. The flange material is 18% chromium with 8% nickel and carbon, manganese, phosphorus, silicon and sulfur.
This composition makes the stainless steel 304 flanges to be stronger and to have good general corrosion resistance. The minimum yield strength of these flanges is at 205MPa and the minimum tensile strength is 515MPa. There are different types of flanges in this grade. The ss 304 blind flange is used to close or end a pipeline. The blind flange can be permanently welded onto the pipe or be fitted with bolts for temporary closures. The ss 304 slip on flange is easy to install on seamless pipes. The slip on flanges can also be adjusted for the connection location as they allow the pipes to slip onto them.
The different standards and specifications such as the uns s30400 WNRF flange control the dimensions of the flanges. The stainless steel flanges usually come in the size range of ½ inches to 48 inches. Special flanges can be produced for special purposes with higher sizes as well. The din 1.4301 flange is one of the most used in the world because of the low cost and relatively high strength. Please feel free to contact us for more information on the different types of flanges and the ss 304 flanges price list.
