苏联第十个五年计划期间,在提高客货车技术水平、强度、可靠性和耐久性方面采取了许多重大的措施。首先在制造客货车时采用了09Г2Д和09Г2CД含铜钢,可使主要零部件的耐腐蚀性能提高20—30％;接着扩大了10ХНДП钢的应用范围,其强度超过09Г2Д钢10—15％,耐腐蚀性能超过1—3倍;同时,掌握了用含锰低合金钢和含锰、钒低合金钢成批生产货车转向架的铸钢件(侧架和摇枕)以及车钩装置的技术,部件的可靠性提高了0.5—1倍。由于车辆技术水平的提高,1976—1980年间将1974年后制造的货车轴载荷从21—21.5吨
During the tenth five-year plan of the Soviet Union, many major measures were taken to improve the technical level, strength, reliability and durability of vans. First used in the manufacture of vans 09Г2Д and 09Г2CД copper-containing steel, the main components of the corrosion resistance can be increased by 20-30%; then expanded the scope of application of 10ХНДП steel, the strength of more than 09Γ2Д steel 10-15%, resistance Corrosion performance of more than 1-3 times; the same time, mastered the use of manganese low alloy steel and manganese, vanadium low alloy steel batch truck truck bogie (side frame and bolster) and the coupler device technology, components The reliability is improved 0.5-1 times. Due to the improvement of vehicle technology, the freight axle load made after 1974 will be reduced from 21-21.5 tons
