Alloy Steel Forgings

Forged alloy steel is a steel that has had small amounts of one or more alloying elements, other than carbon, added to its overall content. These added elements can include manganese, silicon, nickel, titanium, copper, chromium, aluminum and more. These added elements create specific properties for forgings that are not found in regular carbon steel forgings. In addition, alloy steels have become increasingly popular due to their availability, lower economical cost, excellent mechanical properties and ease of processing.

Forged Alloy Steel Applications and Industries

 Our alloy steel forgings serve a variety of industries which include, but are not limited to:
  • Crankshafts
  • Machine Parts
  • Fasteners
  • Gearing

Alloy Steel Forging Options & Characteristics

Depending on your project needs there are a wide range of available options when it comes to alloy steel grades. As an alloy steel forging manufacturer our alloy steels can be heat treated to improve their machinability, strength and ductility. By adding certain elements to your steel, you will see a wide range of differing results, including the following:

  • Nickel & Copper – Improves corrosion resistance, while adding increased strength.
  • Chromium, Vanadium, Molybdenum & Tungsten – These elements will increase strength through the formation of second phase carbides.
  • Manganese, Silicon, Nickel & Copper – The addition of these elements increases strength by forming solid solutions in ferrite, which is ideal for extreme heat exposure.
  • Molybdenum – When molybdenum is added by itself it helps the steel resist embrittlement.
  • Cobalt, Chromium & Nickel – These added elements improve retention of strength and ductility at higher service temperatures.
  • Silicon & Nickel – Retention of ductility and impact is increased is improved at low service temperatures through the addition of these elements.

The industry that is utilizing the forged alloy steel and its intended application will dictate the type of alloy steel forging that is necessary.

Open-Die Forged Alloy Steel

Through the open-die alloy steel forging process thermal and mechanical energy is applied to steel billets or ingots, which then changes the shape of the alloy while in a solid state. Open-die forged alloy steel products are stronger and more reliable than castings since forging involves alteration of the grain flow imitating the shape of the part. The thermal cycle and deformation process leads to grain refinement and recrystallization which eventually strengthens the resulting steel product.

Additionally, as an open-die alloy steel forgings manufacturer our specifications include: AISI, ASTM, AMS, API, SAE, ASME, AWS, JIS and GB. Our forgings are available in many custom 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.

Forged Alloy Steel Benefits

There are a wide range of advantages associated with alloy steel forgings. At Great Lakes Forge we understand the value in creating advanced quality alloy steel forgings for your project needs. Some of the main benefits of forged alloy steel include the following:

  • Forged alloys eliminate the occurrence of shrinkage, porosity, cavities which are usually encountered in castings.
  • The grain structure of forged alloys provides high wear resistance.
  • Forged alloy steel is tougher and more robust than casted steels
  • Forged alloy steels high strength is reinforced through added elements that have been introduced to the carbon steel.
  • The impact strength of forged alloy steel is higher than that of casted steel.
