Description

Изобретение относитс к области изыскани износостойких сталей.This invention relates to the field of finding wear-resistant steels.

Известна сталь, содержаща хром, вольфрам , ванадий, молибден, кобальт, бор, титан, цирконий.Famous steel containing chromium, tungsten, vanadium, molybdenum, cobalt, boron, titanium, zirconium.

Предложенна сталь отличаетс от известной введением ниоби и новым соотношением компонентов. Это обеспечивает стали более высокую твердость в литом состо нии в крупных сечени х.The proposed steel differs from that known by the introduction of niobium and the new ratio of components. This provides steel with higher hardness in the cast state in large sections.

Сталь имеет следующий состав (в %): углерод1,3-2,5Steel has the following composition (%): carbon 1.3-2.5

Сталь имеет твердость более 60 HRc в литом состо нии на валках диаметром 150- 250 мм. Отсутствие операции закалки обеспечиваетSteel has a hardness of more than 60 HRc in the cast state on rolls with a diameter of 150-250 mm. No quenching operation provides

в валках резкое снижение внутренних напр жений и повышение эксплуатационной стойкости . Изготавливать валки из такой стали можно двухслойным методом центробежного лить с основой из сравнительно м гкого конструкционного материала.in rolls, a sharp decrease in internal stresses and an increase in operational durability. The rolls can be made of such steel by the two-layer method of centrifugal casting with a base of relatively soft structural material.
