Description

В насто щее врем  дл  изготовл ени  деталей , подвергаемых цементации или цианированию , используют р д сталей, например следующего состава, %:At present, a number of steels, for example of the following composition, are used for the manufacture of parts subjected to cementation or cyanation, for example:

0,18 -0,24 0,17 -0,37 0,8 -1,10.18 -0.24 0.17 -0.37 0.8 -1.1

Предлагаема  сталь отличаетс  от известных дополнительным легированием малыми добавками молибдена, ванади , ниоби , азота и алюмини .The proposed steel differs from the known additional doping with small additions of molybdenum, vanadium, niobium, nitrogen and aluminum.

Химический состав новой стали, %:Chemical composition of new steel,%:

Состав стали, %:Composition of steel,%:
