Which hardness is higher at tempering temperature for alloy steels than for carbon steels with the same carbon content
The hardness of alloy steel should be higher, and many alloy elements added to the alloy steel can improve the strength and hardness of the steel,
Such as Mn, Si, Ni, Cr, Mo, W, V, Ti, Ai, etc.
How many kinds of carbon steels are classified according to their chemical composition?
