Features of Low-Alloy Chromium Corrosion-Resistant Steel Alloyed with Nitrogen Structure Formation

Abstract

Chromium stainless steels alloyed with nitrogen are studied by experiment. Electron microscopic study of excess phase precipitation makes it possible to identify the types of particles formed at different stages of processing and to assess the degree of their effect on properties. It is established that an increase in the strength of steel tempered at 400°C may be connected with formation during tempering of segregations of various atoms at dislocations with subsequent formation of particles coherent with the matrix, and subsequently losing coherence.
