The temperature range of forged flanges depends on the material and specifications used. In general, the forging temperature range of common carbon steel, stainless steel and alloy steel flanges is generally between 900 ° C and 1300 ° C. Among them, the forging temperature of carbon steel flange is usually between 1000 ° C and 1250 ° C, and the forging temperature of stainless steel flange and alloy steel flange is relatively high, generally between 1150 ° C and 1300 ° C. It should be noted that the specific forging temperature should also be evaluated and determined according to the selected material, process requirements, workpiece shape and other factors. When choosing and controlling the forging temperature, it is necessary to consider the thermal expansion and plastic deformation ability of the material and avoid the oxidation and burning of the material caused by too high temperature. Therefore, before forging the flange, it is best to consult a professional material engineer or refer to the appropriate standard or specification to obtain an accurate temperature range.
