Предложение относитс  к области изыскани  материалов дл  инструмента, работающего на больших скорост х резани  нри повышенных температурах.The proposal relates to the field of research materials for tools operating at high cutting speeds at elevated temperatures.

Известна сталь, содержаш,а  хром, вольфрам , ванадий, молибден, кобальт и азот.Known steel, containing, and chromium, tungsten, vanadium, molybdenum, cobalt and nitrogen.

В отличие от известной предлагаема  сталь содержит дополнительно 0,08-0,1% титана, что повышает ее износостойкость без увеличени  хрункости и, кроме того, предупреждает деазотирование материала.In contrast to the known steel, the proposed steel contains an additional 0.08-0.1% titanium, which increases its wear resistance without increasing the crunchiness and, in addition, prevents the diazotisation of the material.

Предлагаема  сталь имеет The proposed steel has
