42CrMo4 steel is the one of the frequently used alloy steel that characterized by its high strength, great toughness, and good hardenability. It is certtainly a chromium-molybdenum one that is characterized by the European standard EN 10083-3 The “42” stands for the approximate carbon content which is 0.42% (carbon), while CrMo means chromium (Cr) and molybdenum (Mo) are added as alloying components.

1215 carbon steel that is also called resulfurized carbon steel is a free-machining steel possessing the higher sulfur percentage than standard carbon steels. The improved sulfur content can offer better machinability through the formation of ferric and manganese sulfides, which will act as chip breakers during machining operations. 

The 4340 steel, a high-strength and tough alloy steel is well-known for its hardenability, strength and toughness. It is classified as a member of the Ni-Cr-Mo steel family and is given the designation 4340 by the AISI (American Iron and Steel Institute) SAE (Society of Automotive Engineers) standard.

The 4140 steel is a low alloy steel part enriched by chromium, molybdenum and manganese, known for its distinctive quality of high toughness, high torsional strength and good fatigue strength. This composite structure provides with excellent toughness, strength, and wear resistance.

MnCr1045 carbon steel is one of the most spread medium-carbon alloys with a carbon content of 0.45%, appreciated for being a good balance of strength, hardness, machinability and affordability. This wide variety of applications includes gears, shafts, bolts, and other machine components This metal has good weldability and machinability that processing for the enhanced properties is possible, usable in the normalized state which provides uniformity in microstructure and mechanical properties.

1018 carbon steel is a low-carbon alloy, containing approximately 0.18% (by weight) of carbon. For carbon steel, it is one of the most commonly available grades, and it is recognized as highly weldable, machinable, and versatile.
