Description

Изобретение относитс  к области металлургии, в частности к стал м дл  инструментов холодной деформаци Известна инструментальна  сталь марки X2MO flJ. Недостатком этой стали  вл етс  низка  износостойкос Цель изобретени  - повышение износостойкости . Это достигаетс  тем, что предлож на  стиль дополнительно содержит ти тан и азот при следующем соотношени компонентов, вес.%: Углерод 0,5-0,65 Марганец 0,4-0,7 Кремний 4-4,8 Хром5-6 Молибден 1,2-1,5 Ванадий 0,5-0,8 Титан 0,01-0,05 Азот0,01-0,05 Железо Остальное Испытани м бьши подвергнуты три состава предложенной стали. Стали, изготовленные из этой стали, проковывают на молоте. Температура нагрева , вы1держка 0,5 ч. В результате контрол  за процессом ковки установлено, что сталь пластична , м гка , хорошо куетс  в интервале температур 1200-850 0 на поковках отсутствуют поверхностные трещины и дефекты. Наибольша  пластичность стали при температуре . В указанном интервале слитки можно деформировать со степенью деформации до 50% эА обжатие беэ по влени  поверх ноCTHIJX дефектов металла.This invention relates to the field of metallurgy, in particular to steel for cold deformation tools. Known tool steel grade X2MO flJ. The disadvantage of this steel is low wear resistance. The purpose of the invention is to increase wear resistance. This is achieved by the fact that the proposed style additionally contains titanium and nitrogen in the following ratio of components, wt.%: Carbon 0.5-0.65 Manganese 0.4-0.7 Silicon 4-4.8 Chromium 5-6 Molybdenum 1 , 2-1.5 Vanadium 0.5-0.8 Titanium 0.01-0.05 Nitrogen 0.01-0.05 Iron Remaining Three compositions of the proposed steel were subjected to tests. Steel, made of this steel, forged on a hammer. Heating temperature, holding 0.5 hours. As a result of monitoring the forging process, it was found that the steel is ductile, soft, and fits well in the temperature range of 1200-850 0 on the forgings there are no surface cracks and defects. The greatest ductility of steel at temperature. In the specified interval, ingots can be deformed with a degree of deformation up to 50% eA, compression of the appearance of metal defects on the surface of CTHIJX.
