is a popular metal alloy consisting mostly of iron, typically with small amounts of carbon although other elements may be included such as manganese, chromium, vanadium and tungsten.

Modern steel making began in 1858 with the capability to produce large quantities cheaply. Mild steel is often used for numerous applications where wrought iron was used previously. Steel shapes include sheets, rods, plates, hexes, pipes and a variety of beams.

Steel is known for its low strength-to-weight ratio and is available in many alloys.

Properties of Steel

  • High thermal conductivity
  • Ductile and malleable
  • Low tensile strength
  • Lightweight but exceptionally strong
  • Good corrosion resistance, especially with stainless steel

Steel is a popular choice for many metal products and components:

Auto Parts
Optical Reflectors
Cooking Utensils
Aircraft Parts
Lighting Fixtures
Medical Devices
Electronic Enclosures
Engine Parts
Handles and Knobs

Popular Steel Alloys

Steel 12L14

Known for it’s excellent machinability resulting in improved surface appearance.

Steel 4140

AKA “chrome-moly”, this alloy has good fatigue, abrasion, and impact resistance. 4140 is readily formed and machined in its annealed state and can be heat treated to increase toughness and wear resistance. 4140 is ideal for crankshafts, gears, axles, and shafts.

Steel 4130

Similar to 4140, but has better weldability and formability. 4130 is often used to meet military specifications and for demanding structural applications.

O1 Tool Steel

01 has a good combination of machinability and resistance to wear and abrasion. It is often used in punch and die tooling plus cams, bushings, guides, and gauges.

D2 Tool Steel

D2 has great wear and abrasion resistance. This alloy is known for its hardness and is commonly used for long-run dies and blanking, as well as shear blades, burnishing tools, and gauges.

Steel 1018

This alloy is known for weldability and better machinability than the lower carbon steels. 1018 is a common cold-rolled steel with good strength and some ductility. It is similar to A36 but has a better surface finish.

Steel A36

A36 is a common hot-rolled steel. It has a rougher surface than cold rolled steels but a lower yield strength than 1018, thus is easier to bend. A36 is more difficult to machine than 1018.

Steel 1008

1008 has good formability and comparatively high strength, plus an excellent surface finish.

Machining Options

CNC Milling

Mills use rotating tools to cut material into almost any 3D shape. CNC Mills can work with tight tolerances.

Waterjet Cutting

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 Turning

CNC Lathes feed cutting tools into rotating material. Turning is mainly used to produce precise, cylindrical parts.

Wire EDM

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

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.

Turret Punching

CNC Turret Presses create 2D parts by rapidly punching predetermined shapes into sheet material. Cost-effective for production runs of simple metal parts.

Plasma Cutting

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.

Secondary Manufacturing

After manufacturing, parts may require additional processing. Secondary services include CNC bending, grinding, tapping, knurling and more.

Surface Finishing

Finishing processes are used to enhance appearance, surface durability, and corrosion resistance. Options include powder coating, anodizing, plating, polishing and more.

  • Applications & Advantages

  • More About Steel

  • Available in numerous alloys spanning a wide variety of properties, steel is inexpensive and is used in countless industries. It is easily formed to make enclosures and can be hardened. Steel is magnetic and has a low strength-to-weight ratio. Many alloys can be machined easily.
  • Steel is used widely in the construction of roads, railways, infrastructure, and buildings. Most large modern structures, such as stadiums and skyscrapers, bridges, and airports, are supported by a steel skeleton.
  • Steel is also used in appliances, cars, bolts, nails, screws, shipbuilding, mining, aerospace, material moving equipment, office furniture, tools, armor, etc.
  • More About Steel

  • Stainless Steel: Stainless Steel contains a minimum of 10% chromium and is a more expensive alternative to traditional steel. It’s typically used for parts which require higher corrosion resistance and durability than mild steel offers.
  • Spring Steel: Spring Steel is a class of steel alloys that are typically heat-treated for use as springs in applications including vehicle suspensions, helical springs, bed springs, wind-up toys and more. Spring Steel has high yield strength and is resistant to deformation.
  • Sheet Steel: Steel sheet fabrication is often done using processes such as wire EDM, turret punching, waterjet cutting, and more. A steel sheet at 1/4 inch thickness is approximately 0.071 lb per sq. inch.
