Description

Изобретение касаетс  материалов, предназначенных дл  изготовлени  плакирующего сло  двухслойных режущих самозатачивающихс  элементов почвообрабатывающих мащин , в частности стали.The invention relates to materials intended for the manufacture of a cladding layer of two-layer cutting self-sharpening elements of tillage machines, in particular steel.

Известна сталь, содержаща  углерод, хром, ванадий, железо.Known steel containing carbon, chromium, vanadium, iron.

Предложенна  сталь отличаетс  от известной пониженным содержанием хрома. Это обеспечивает стали более высокую износостойкость и меньшее сопротивление гор чей пластической деформации.The proposed steel differs from the known lower chromium content. This provides steel with higher wear resistance and lower resistance to hot plastic deformation.

Предложенна  сталь имеет следующий состав, %:The proposed steel has the following composition,%:

Углерод1,4-;1,7Carbon1,4-; 1,7

Хром3,5-4,7Chrome3.5-4.7

Ванадий0,8-1,2Vanadium 0.8-1.2
