Strong Fatigue Performance Gb 42crmo Alloy Material With Abundant Inventory - China

gb 42crmo alloy material is a high-strength alloy structural steel widely used in heavy machinery, automobile, aerospace and other fields due to its excellent comprehensive mechanical properties (such as high strength, good toughness and wear resistance).

its fatigue performance* is an important indicator to measure its ability to resist failure under cyclic load.

: the fatigue limit of gb 42crmo alloy material is usually in the range of 400–500 mpa, and the specific value depends on the heat treatment state, surface quality and loading conditions.

- after quenching and tempering treatment (quenching + tempering), its fatigue limit can be further improved.

at 10^7 cycles, the fatigue strength of gb 42crmo alloy material is about 40%–50% of its tensile strength.

for example, if the tensile strength is 1000 mpa, the fatigue strength is about 400–500 mpa.
