C40 tempered steel
It is a steel commonly used in the manufacture of mechanical parts such as shafts, gears, bearings, camshafts and other machinery parts that require high mechanical strength.
One of the main characteristics of C40 steel is its resistance to plastic deformation and fracture due to its high toughness.
It also resists atmospheric corrosion and abrasion, making it an excellent choice for applications in areas such as the chemical and mining industries.
Tempered steel 39NiCrMo15
This steel is commonly used in high-strength, high-temperature applications in industries such as aerospace and automotive.
It is characterized by high tensile strength, fatigue, corrosion and high temperature resistance, making it ideal for applications that resist wear and abrasion.
It can be subjected to heat treatments to improve its properties, as long as they are performed carefully according to the specific end application.
