Useful information for 42CrMo4 Steel’s specification and chemical composition

42CrMo4 Steel is the popular steel which belong to EN10083 standard. 42CrMo4 Steel have huge advantage on katalor company. The bellowing is some detail information for 42CrMo4 Steel specification and chemical composition and others.


Effect of Hydrogen on Tensile Properties of 42CrMo4 Steel at Different Temperature Quenching and Tempering:
 

1.The hydrogen trapped in the Q + T steel increases as the tempering temperature decreases.

2.The tensile properties are hardly affected in the presence of hydrogen.
Hydrogen embrittlement increases the hardness and lower displacement of the steel.

  1. Due to hydrogen embrittlement, changes in the microscopic mechanism of failure were observed.

The brittleness index and the failure microscopic mechanism are explained by FEM simulation.
