Importance of stainless steel flanges in industries The stainless steel flanges, in the various types (flat, blind, with step, etc.), can be divided into two macro-categories, which differ in their production process: investment casting and forging. Slip on flanges manufacturers in India provides all types of flanges worldwide.
Investment Casting: Investment casting is the production treatment that takes place through the casting of liquid steel in a disposable mould; this method allows the creation of even more complex shapes and components thanks to the molds above with defined shapes. The molten steel is poured into molds positioned in sequence, ensuring uniform filling until the desired shape is achieved. After cooling, the shell of the mold is broken to obtain the raw product. In the case in question, the raw flange will be subjected to various processes, annealing, turning and finishing, obtaining the finished product ready for assembly. The advantages of flanges produced through investment casting are the low cost deriving from mass production and the total uniformity of the finished product. Forging: In the case of stainless steel flanges, the forging process is carried out by plastic deformation of the steel itself. A steel round or plate is overheated until it reaches a temperature higher than the recrystallization temperature so that it can be worked using presses to obtain a hot forging of the product (alloy).
