Description
(54) ВЫСОКОПРОЧНАЯ СТАЛЬ(54) HIGH STRENGTH STEEL
Литейные свойства сравниваемых сталей при температуре заливки проб от 1600°С приведены в табл. 2.The casting properties of the compared steels at a sample filling temperature of 1600 ° C are given in Table. 2
Механические свойства известной и предлагаемой сталей после закалки от 900°С и отпуска при 650°С, 1 ч приведены в табл. 3.The mechanical properties of the known and proposed steels after quenching from 900 ° C and tempering at 650 ° C, 1 hour are given in Table. 3

Повышение содержани кремни и марганца , а также микролегирорани боро:,: значительно повышает прокаливаемость стали, что важно при закалке ТВ4 литых деталей.Increasing the content of silicon and manganese, as well as micro-alloying boro:,: significantly increases the hardenability of steel, which is important when quenching TB4 cast parts.
Введение молибдена в сталь помимо повышени прочности и износостойкости обеспечивает подавление отпускной хрупкости в массивных детал х.The introduction of molybdenum into steel, in addition to increasing strength and wear resistance, suppresses temper brittleness in massive parts.
Исследовани износостойкости в услови х абразивного износа провод т на машине Х4-Б, в услови х фрикционного износа - на машине МИ. Относительную износостойкость (е) образцов подсчитывают по формулеInvestigation of wear resistance under abrasive wear conditions was carried out on an X4-B machine, and under frictional wear conditions, on an MI machine. The relative wear resistance (e) samples calculated by the formula

В качестве эталона за единнцу износостойкости принималась известна сталь (состав 3), имеюща минимальную твердость из трех составов известной стали. Величину износа определ ют потерей веса образца. Фрпкционные пары выбирают, исход из реальных условий эксплуатации.As a reference for wear resistance, steel was known (composition 3), having a minimum hardness of three compositions of known steel. The amount of wear is determined by the weight loss of the sample. The operating pairs are selected based on the actual operating conditions.
Механические свойства исследованных сталей, прокаливаемость и износостойкость представлены в табл. 3 и 4.The mechanical properties of the investigated steels, hardenability and wear resistance are presented in Table. 3 and 4.
Прокаливаемость и износостойкость исследованных сталей приведены в табл. 4.Hardenability and wear resistance of the investigated steels are given in table. four.
