The average forging temperature necessary for hot forging of different metals is Up to 1150°C for Steel . 360 to 520°C for Al-Alloys. 700 to 800°C for Cu-Alloys. During hot forging , the billet or bloom is heated either inductively or in a forging furnace or oven to a temperature above the recrystallization point of the metal. A Review on Field Areas of Research in Forging Process Forged Wheels Forging Defects Pdf Heavy Steel PlateDefect removal is a critical area of forging research because of the high losses resulting from rejections or rework in forging industry.

API 5L X52 Pipe Specification (PSL1 PSL2) - Advantages of Forgings-Forging Processes Scot ForgeAt its most basic level, forging is the process of forming and shaping metals through the use of hammering, pressing or rolling. The process begins with starting stock, usually a cast ingot (or a "cogged" billet which has already been forged from a cast ingot), which is heated to its plastic deformation temperature, then upset or "kneaded" between dies to the desired shape and size.

Development of a new process for forging plates using Forged Wheels Forging Defects Pdf Heavy Steel Plate
A new method of plate forging with V-shaped dies is proposed. The deformation state of a metal workpiece during forging has been investigated. The proposed method of forging increases the uniformity of the strain distribution with a high level of strain in the workpiece. The values of angles for V-shaped dies range from 120° to 140°. This range of die ERVIN INDUSTRIESgrinding wheels last longer.
