Steel is a widely used material in the industry. Steel is an alloy formed by the combination of iron and carbon. The properties of this alloy vary depending on the amount of carbon, the presence of other elements and heat treatments. 42crmo4 steelis a type of steel that is especially known for its excellent mechanical properties . In this blog content, we will give detailed information about 42crmo4 steel properties, uses and advantages.
42CrMo4 Steel Properties
42crmo4 steel is a steel with a high carbon and alloy content. This steel is hardenable and provides high strength and toughness. 42crmo4 steel has a higher fatigue strength than most types of steel. In addition, thanks to its heat-resistant properties, it can be used in industrial applications exposed to high temperatures.
The chemical composition of 42crmo4 steel is as follows:
- Carbon (%C): 0.38-0.45
- Silicon (Si %): 0.40 maximum
- Manganese (%Mn): 0.60-0.90
- Phosphorus (%P): 0.025 maximum
- Sulphur (%S): 0.035 maximum
- Chrome (%Cr): 0.90-1.20
- Molybdenum (Mo %): 0.15-0.30
This composition has a decisive effect on the properties and areas of use of the steel.
The mechanical properties of 42crmo4 steel are as follows:
- Tensile strength: 900-1100 MPa
- Yield strength: 650-850 MPa
- Elongation (%): 12-14
- Impact withstand (J): 35-45 at -20°C
The hardening properties of 42crmo4 steel depend on the water cooling process performed during heat treatment. After hardening, steel provides high strength and toughness. Therefore, 42crmo4 steel is especially preferred in applications that require high strength.
Most Commonly Used 42CrMo4 Steel Grades
42CrMo4V
42CrMo4V is a steel grade used especially at high temperatures. This steel consists of an alloy containing chromium, molybdenum and vanadium. This alloy increases the strength and hardness of the steel.
42CrMo4+QT
42CrMo4+QT is a hardened steel grade. This steel is ideal for use under heavy loads with its high strength and hardness properties. QT stands for “quench and temper” and is made to have better properties by hardening the steel and then reheating and annealing.
42CrMo4+QTz
42CrMo4+QTz is a hardened and enriched steel grade. This steel consists of chromium, molybdenum and vanadium alloys, as well as an alloy containing titanium and boron. This alloy increases the fatigue strength of the steel and makes it longer-lasting.
42CrMo4+HH
42CrMo4+HH is especially ideal for applications that require high strength. This steel is produced by the “hot-rolled” process and is ideal for use under heavy loads with its high strength and hardness properties.
