Carbon Steel (20#, 35#, 45#, A105, Q235, 20CrMnTi, etc): There are four main grades of carbon steel: low carbon steel, medium carbon steel, high carbon steel, and very high carbon steel. Depending on the amount of carbon present in the material, carbon steel forgings are hardenable by heat treatment to increase yield and impact strength as well as wear resistance.
Low or mild carbon steel contains 0.05% to 0.26% carbon and encompasses grades 1018 and 1020. The lower carbon content causes the material to be more ductile and less brittle, making mild carbon steel a good choice for forging. Medium carbon steel contains 0.29% to 0.54% carbon and includes steel grades 1141. Containing a higher level of manganese, medium carbon steel can be used in the quenched or tempered form for forged crankshafts and many other types of forgings. High carbon steel and very high carbon steel exhibit hardness as well as resiliency and are brittle due to their higher carbon contents, between 0.55% and 2.1%.
Alloy Steel (20Cr, 20CrMo, 30CrMo, 35CrMo, 42CrMo, etc): Alloy steels encompass a wide range of iron-based metals which contain higher levels of chromium that do not exceed 3.99%. Metals that contain greater amounts of chromium are classified either as tool steels or stainless steels. Alloy steels vary in their alloying elements which determine the properties of a particular material.
Aluminum alloys can be used for drop forging. Main grades in aluminum forgings include: AL 6061, AL 6063, AL6082, AL 7075, etc.
Normally, steel forgings are widely used for industries due to the greater strength of it’s refined grain structure, as well as it’s machinability, and it’s low porosity, compared to steel castings. Our steel forgings are made by closed-die, or precision forging. Our lower tooling cost makes steel forging the best choice even at small quantities.
EMP offer every imaginable secondary operations, including heat treatment, machining, surface coating. We provide all the value added services to make procuring steel forgings as easy and as cost-effective as possible.
