What is alloy steel 42CrMo4 fatigue limit

42CrMo4 steel is mainly composed of chromium, molybdenum and so on chemical components, and it belongs to alloy steel. What is 42CrMo4 fatigue limit?

42CrMo4 fatigue limit is the stress level below which an infinite number of loading cycles can be applied to 42CrMo4 material without causing fatigue failure. 42CrMo4 fatigue limit is also known as 42CrMo4 endurance limit or 42CrMo4 fatigue strength.

The alloy steel 42CrMo4 has fatigue limit. Besides, it has advantages of high strength, high toughness, good hardenability, temper brittleness, good impact resistance after quenching and tempering, and good low temperature impact toughness, etc.
