Conclusion

The susceptibility of steel to corrosion cracking depends to a large extent on the tempering temperature. With increasing tempering temperatures the susceptibility of oil-quenched steels decreases. At the tempering temperature at which preferential martensite decomposition occurs in former austenite grain boundaries one observes an increase of the susceptibility to corrosion cracking. For steels 30Kh-GSA, 30KhGSNA, and 25Kh2GNTA this increased susceptibility occurs on tempering at 250°C, for steel ÉI643 at 400°C, and for steel D at 450–500°C.
