Abstract
The creation of austenitic steels with a supraequilibrium nitrogen con centration increases their strength substantially. However, their plas ticity and fracture toughness can be decreased. In particular, such st eels can be susceptible to delayed fracture characteristic for high-st rength steels with a martensite or bainite structure. It is of interes t to investigate the susceptibility of austenitic Cr - Ni - Mn steels with different concentrations of nitrogen to delayed fracture under th e action of stresses. corrosive media, and hydrogen.
