The effect of the initial microstructure of low-alloy tube steel 13KhFA on its mechanical properties after quenching from the intercritical temperature range (ICR) has been studied. It has been established that the maximum impact toughness KCV-80 is achieved in the case of the initial quenched structure, and the lowest values correspond to the initial annealing. The dependences of the KCV-80 on the temperature of the second quenching for these initial states are fundamentally different as well. © 2014 Pleiades Publishing, Ltd. Source

Effect of parameters of heat treatment of steel 20 microalloyed with vanadium on its microstructure and mechanical properties has been studied. It has been shown that the normalization performed before quenching from the intercritical temperature range and high-temperature tempering lead to the formation of an inhomogeneous microstructure with a preferred distribution of cementite particles near the boundaries of ferrite grains. The formation of such a microstructure is accompanied by a decrease in the cold resistance. © 2010 Pleiades Publishing, Ltd. Source

The fundamental technical specifications on continuous-cast boiler-steel billet are outlined. The basic parameters of the production technology proposed for continuous-cast steel 20 and steel billet (diameter 150–550 mm) are presented, as well as test data for experimental melts of the steel. The proposed technology produces metal of high quality, meeting (or exceeding) all the requirements on steel for boiler pipe. © 2014, Allerton Press, Inc. Source

A new production technology for centrifugally cast 04Х14ТЗР1Ф boron-steel has been developed. In addition, technology has been developed for the production of hot-rolled 290 × 12 mm pipe from such blanks on a TPU 8-16″ system with Pilger mills and for the conversion of such pipe to hexahedral pipe blanks (dimensions 257 +2/–3 × 6 +2/–1 × 4300 +80/–30 mm). The hexahedral pipe blanks produced by this means meet the requirements on the geometric dimensions, mechanical properties, and intercrystallite corrosion in Technical Specifications TU 14-3-1630–89 for the manufacture of racks used in holding tanks at nuclear power plants and in spent-fuel transportation. © 2016, Allerton Press, Inc.
