Glossary of Terms
Alloy Steel Forgings
It is a type of steel with minor amounts of one or more alloying substances added to its overall composition. Manganese, silicon, nickel, titanium, copper, chromium, aluminum, and other elements can be added. Forgings with these additional components have unique qualities not present in forgings made of standard carbon steel.
Due to their accessibility, lower economic cost, superior mechanical qualities, and simplicity of processing, alloy steels have also grown in popularity.
Aerospace Material Specifications
The Society of Automotive Engineers, shortly known as SAE, devised the Aerospace Material Specifications (AMS). Aerospace material processing procedures, tools, and processes are standardized by AMS requirements, which are compiled in an extensive database of individual directives. These are consistently updated and altered to reflect advancements in process and material research.
American Society for Testing and Materials (ASTM)
In the nonprofit American Society for Testing and Materials (ASTM), manufacturers, users, consumers, and academic and governmental officials work together to create voluntary consensus standards for materials, goods, systems, and services. Around the world, ASTM has 30,000 individual and institutional members.
Billet
It is a type of material and doesn’t always describe how (or how well) the end product was made. Billet metal is a solid length of material that has been hot rolled or continuously cast into shape. It frequently has a square or circle profile. In CNC machining, billet material is commonly utilized.
Cast Metal
It is made of metal that has been heated past its melting point and poured into a mold using a variety of procedures, such as gravity casting or high-pressure die casting, to create the shape of the desired result.
Forged Metal
It is heated to a malleable state (as opposed to molten) and shaped under pressure. Horseshoes, swords, and armor were formerly made using this method by blacksmiths and ironworkers. Instead of a hammer and anvil, newer methods typically use high-pressure stamping.
Abrasive Blaster Cleaning
This process is the most thorough way to get rid of rust and mill scale from steel surfaces. The technique uses centrifugal impellers or a jet stream of compressed air to ‘blast’ clean the steel surface with high-velocity abrasive particles.
Eliminating impurities before coating, painting, or lining, aids in surface preparation. Rust and other pollutants could interfere with paint adhesion or, in the worst situations, jeopardize the integrity of the metal surface itself.

Carbon Steel
Carbon is a unique sort of steel that is present in larger concentrations in carbon steel than in other types of steel. Most steel varieties have a carbon percentage that ranges from 0.05% to 0.3%. In contrast, carbon steel contains up to 2.5% carbon.
Although 2.5 percent carbon may not seem like much, it brings with it several desirable advantages that are unique. Increased strength is just one of the benefits of choosing carbon steel over conventional steel.
Carbon makes it stronger by moving around the crystal lattice of iron or steel. Compared to other varieties of steel, carbon steel is less likely to stress and break under pressure. Due to this, it is especially useful in applications where strength is essential.
Closed Die Forging
This process involves shaping hot metal inside the walls or cavities of two dies that join to enclose the workpiece on all sides. Either can hold the complete forging impression, or it can be split between the top and bottom dies.
The terms “impression-die forging” and “closed-die forging” are frequently used interchangeably to describe a closed-die process in which the dies have a feature for regulating the flow of surplus material, or “flash,” that is produced. In contrast, the material is deformed in a hollow during flashless forging, which leaves little to no room for extra material to escape.
Impression Die Forging
It is a method of metal deformation in which a billet is squeezed between two sets of die to create a complicated item. The term “Impression” describes the pre-cut profile of the dies used in the forging process, which are tailored based on the item being produced.
Die Lubricants
These are lubricants developed to promote film formation and wetting on the surface of the mold at the extremely high temperatures generated during the die-casting process.
Drop Forging
This is a method of creating metal. Workpieces are placed inside dies and hammered until they take on the die’s shape. The upper die is a moving hammer dropped into the workpiece to distort it, while the lower die is a stationary component.
Idler Roll
An idler is made up of one or more rollers, each of which has one or more bearings to keep it rolling freely. A framework positioned over the conveyor stringers supports or suspends the rollers. Trough idlers, flat return idlers, impact idlers, and training return idlers are the four types of idlers that are most frequently employed.
Machining
The process of machining involves cutting away a material, usually metal, to produce components for tools, machinery, transportation, and other things. Machine shops and machinists transform raw materials into useful tools by making accurate cuts using tools like lathes, mills, and drill presses.
Although it may be used on various other raw materials, machining is typically employed to shape metals. Machine shops use 3D printers to add material and instruments like mills, lathes, and drill presses to cut it.
