Steelis a popular metal alloy consisting mostly of iron and some carbon. Other elements are sometimes added, such as manganese, chromium, vanadium, and tungsten.
Modern steelmaking began in 1858 when it became possible to produce large quantities economically. Steel is thermally conductive, highly corrosion-resistant, ductile, and malleable.

Mills use rotating tools to cut material into almost any 3D shape. CNC Mills can work with tight tolerances.
Waterjets mainly cut sheet material into 2D parts using a high-pressure stream of water and abrasive. Waterjet cutting is suitable for most materials and yields clean edges.
CNC Lathes feed cutting tools into rotating material. Turning is mainly used to produce precise, cylindrical parts.
Die-Sink and Wire EDM machines create parts by using recurring sparks to remove material. Recommended for intricate designs requiring sharp inside corners and high dimensional accuracy.
Laser cutting is often used to produce 2D parts from sheet metal. A laser beam vaporizes a cut path to achieve the desired shape. Great for prototypes and short runs.
CNC Turret Presses create 2D parts by rapidly punching predetermined shapes into sheet material. Cost-effective for production runs of simple metal parts.
CNC Plasma Cutters use a high-velocity stream of ionized gas to cut parts out of sheet metal. Excellent for producing 2D parts when working with thick metal sheets.
After manufacturing, parts may require additional processing. Secondary services include CNC bending, grinding, tapping, knurling and more.
Finishing processes are used to enhance appearance, surface durability, and corrosion resistance. Options include powder coating, anodizing, plating, polishing and more.
Popular Steel Alloys
Excellent machinability and surface appearance. Typical applications include brake hose ends, pulleys, and hydraulic fittings.
Good fatigue, abrasion, and impact resistance. Readily machined in an annealed state and can be heat treated. Used in crankshafts, gears, and axles.
Similar to 4140, but has better weldability and formability. Often used for military equipment and in demanding structural applications.
O1 Tool Steel
Highly machinable and resistant to wear and abrasions. Typical applications include punch and die tooling, cams, bushings, cutting tools, and gauges.
D2 Tool Steel
Great wear and abrasion resistance, and known for its hardness. Typically used for long-run dies and blanking, as well as shear blades and gauges.
A common cold-rolled steel with good strength and ductility. Excellent surface finish and weldability, and is more machinable than lower carbon steel alloys. It is often used for mounting plates, spacers and fixtures.
A common hot rolled steel with a rougher surface than cold rolled steels. Lower yield strength than 1018, which makes it easier to bend, but decreases machinability. Often used in base plates, machine frames, and automotive equipment.
Good formability and high strength, with an excellent surface finish compared to other alloys. Commonly used in extruded and cold-pressed parts, home appliances, and automotive applications.
