The forged crankshaft (left) shows how it achieves its strength by compressing the material, and the tighter grain flows along the length. However, while a forged crank is compressed during the forging process, the steel ingot used in a billet crank is already forged, albeit not quite as compressed as in a forged crank. Commonly misidentified as billet rods, fully machined forged steel rods are exactly what the name implies. In short, both billets and ingots are semi-finished steel. If youre here, youre probably going to build your AR-15 using an 80% lower. However, weight will be a factor depending on the properties of the actual metal that is cast or forged. Differences Between Forged Steel and Billet Steel Cranks MidwestSuperCub 4. Most of the billet uppers have heavier walls, and therefore have less flex and are generally stronger, which make them perfect for heavy barreled / precision rifle applications. Since billet rods are often produced in smaller batches or in custom configurations, more time would be needed in creating the design, machine setup and final finishing, and additional labor would be involved, billet rods would be more expensive than a forged rod of the same material. When it comes to billet vs forged aluminum receivers, Caleb talks about grain and likens it to wood grain, and says forging forces the grain to follow the contours of a receiver, trigger guard, etc — while billet machining leaves the part with all the grain in one direction and simply cuts the shapes. Billet steel is stronger than regular steel because the hot rolling process aligns the grain structure of the metal, making it less susceptible to fractures. Raw Material of Forgings: Billet, Bar, Bloom and Ingot. The grain structure of metal is the talking point and when compared between the two, forged is a clear winner. It is heated and hammered into its approximate final shape. Billet metal is a solid length (often in a square or circle profile) of material that has been extruded into shape, either by continuous casting or hot rolling. Billet lowers are a bit heavier than standard forged lowers, and that is the only important difference. Billet pistons are commonly thought to be stronger and tougher than forgings when in fact, their strength properties are surprisingly similar, with forged pistons holding a slight edge due to the improved grain structure contributed by the forging process. For the uninitiated, the two major differences between cast and forged cranks include the material and forming process. The difference between the cast, forged and the billet is somehow categorized into benefits and drawbacks as below: Casting is a highly flexible field in which we have expertise. Author : Rebeca Yu Source : Billet connecting rods made from a single piece of flat forged steel. Forged vs Billet crankshafts , billet steel crankshaft. Since a billet rod is cut from flat steel, the grain doesn’t swirl and flow around the big end of the rod, as in a forged application. If he did metallurgy for that long he would know that billet and forged are nowhere close. Forging requires certain metal properties to work whereas the options are limitless for a billet piece. When it comes to billet vs forged aluminum receivers, Caleb talks about grain and likens it to wood grain, and says forging forces the grain to follow the contours of a receiver, trigger guard, etc — while billet machining leaves the part with all the grain in one direction and simply cuts the shapes. Connecting Rod Tech: Forged And Billet Steel Rods. What is Billet Steel?. As the name suggests, cast cranks are created by pouring molten material (typically.
