Open Die, Seamless & Contoured Rolled Ring Forging
Service Detail from All Metals & Forge Group, LLC
All Metals & Forge Group is a manufacturer of custom forged shapes and an expert in the field of open die forgings. Producing forgings to recognized material standards is a quality benchmark of All Metals & Forge Group, which is an ISO9001-2008:AS/EN9100:2009 Rev C manufacturer.
At 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.

During this hot forging process, the cast, coarse grain structure is broken up and replaced by finer grains. Low-density areas, micro-shrinkage and gas porosity inherent in the cast metal are consolidated through the reduction of the ingot, achieving sound centers and structural integrity. Mechanical properties are therefore improved through the elimination of the cast structure, enhanced density, and improved homogeneity. Forging also provides means for aligning the grain flow to best obtain desired directional strengths. Secondary processing, such as heat treating, can also be used to further refine the part.
No other metalworking process can equal forging in its ability to develop the optimum combination of properties.
Open Die Forging Materials
All Metals & Forge Group forges a wide range of ferrous and non-ferrous alloys in 8 metal families.
- Alloy steel
- Carbon steel
- Stainless steel
- Tool steel
Forgings can be produced to specifications for metal alloys including AISI, ASTM, AMS, API, SAE, ASME, AWS, JIS and GB in many custom forged shapes and heat treated conditions to achieve critical physical properties, such as tensile, yield, elongation and reduction of area for the desired end use as specified by the purchaser.
