【 摘 要 】

In the article are given the analyzing corrosion resistance data of nitrogen containing steels. The resistance on the pitting, crevice corrosion with high nitrogen containing is estimated. The corrosion resistance of the steel 05Kh22AG15N8M2F in the condition after cold deforming in chloride containing substances is defined. Laboratory and field tests two types of steels 05Kh22AG15N8M2F and 12Kh18N10T are provided. It's determined that the samples of the steel 05Kh22AG15N8M2F are demonstrating larger corrosion resistance at the laboratory and field investigations in comparison with the steel 12Kh18N10T. The properties of the steel 05Kh22AG15N8M2F with known AISI 316 are compared. It is established that the steel 05Kh22AG15N8M2F a top of AISI 316 on the resistance to the pitting corrosion and the critical pitting temperature. Pitting Resistance Equivalent (PREN) for the steel 05Kh22AG15N8M2F and the critical pitting temperature are determined.
