With the development of science and technology and industry, the material has put forward higher requirements, such as higher strength, high temperature, high pressure, low temperature, corrosion resistance, wear resistance and other special physical and chemical properties of the requirements, carbon steel can not fully meet the requirements.

Deficiencies of carbon steel:

(1) Low hardenability.Under normal circumstances, the maximum diameter of carbon steel water quenching is only 10mm-20mm.

(2) the strength and strength are relatively low.For example, the σs of ordinary carbon steel Q235 steel is 235MPa, and the σs of low alloy structure steel 16Mn is more than 360MPa.The σ S /σ B of 40 steel is only 0.43, which is much lower than that of alloy steel.

(3) poor tempering stability.Due to the poor tempering stability, carbon steel in the tempering treatment, in order to ensure higher strength needs to use a lower tempering temperature, so that the toughness of steel is low;In order to ensure good toughness, the strength of high tempering temperature is low, so the level of comprehensive mechanical properties of carbon steel is not high.

(4) can not meet the requirements of special performance.Carbon steel in oxidation resistance, corrosion resistance, heat resistance, low temperature resistance, wear resistance and special electromagnetic and other aspects are often poor, can not meet the needs of special performance.
