Prospects of application of structural steels with superequilibrium nitrogen content for high temperature and hydrogen pressure condition

One performed the system analysis of the basic experimentally determined regularities in exhibition of hydrogen embrittlement and cracking of steels under increased temperatures and pressures of hydrogen. The reason of the mentioned phenomenon was the chemical interaction of hydrogen with solid solution carbon at the inner surface of closed micropores. In that connection one substantiated the prospects of nitrogen substitution for carbon in simple and low alloy steels. The problem of the most available technique to prepare those steels with nitrogen superequilibrium content using the most traditional melting techniques was studied
