“…In introducing the production of high reliability pipe, large scale research was undertaken on steel of 20XMФA type, including its structure formation and the development of its mechanical and corrosion properties in quenching and high tempering [3,4]. However, constantly rising requirements on the cold strength of pipe prompted the search for promising methods of heat treatment and eventually the poten tial of the high quality low alloy steel produced at OAO Severskii Trubnyi Zavod.…”

The structure formation in steel as a result of double quenching (the second time from the intercritical temperature range A c1 -A c2 ) and high tempering is established. By EBSD, the crystallo graphic features of the ferritic-martensitic structure formed in single and double quenching and stabilized on tempering are studied. The prospects for improving the mechanical properties of low alloy, low carbon Cr⎯Mo-V steel by quenching from the intercritical temperature range are considered Keywords: low alloy low carbon Cr-Mo-V steel, ferritic-martensitic structure, special boundaries, mechanical properties
