Предложенна  сталь отличаетс  от известной наличием молибдена, повышенным содержанием кремни , пониженным содержанием хрома, отсутствием ванади . Валки, изготовленные из этой стали, обладают повышенной эксплуатационной стойкостью.The proposed steel is distinguished from the known presence of molybdenum, high silicon content, low chromium content, and the absence of vanadium. Rolls made from this steel have a high operational resistance.

Сталь имеет следующий состав (в %):Steel has the following composition (%):
