| classification | According to the content of alloying elements Low alloy steel (the total amount of alloying elements is less than 5%), Medium alloy steel (the total amount of alloying elements is 5%-10%) High alloy steel (the total amount of alloying elements is higher than 10%). According to the composition of alloy elements Chromium steel (Cr-Fe-C) Chromium-nickel steel (Cr-Ni-Fe-C) Manganese steel (Mn-Fe-C) Silicon manganese steel (Si-Mn-Fe-C) According to metallographic organization Pearlite steel Martensite steel ferritic steel austenitic steel ledeburitic steel Divide by purpose structural alloy steel 4cr5mosiv1 Special performance steel |

| Properties of alloy steel plate | (1) Low hardenability Generally, the maximum hardenability diameter of carbon steel by water quenching is only 10 mm-20 mm.. (2) The strength and yield strength are relatively low. For example, the σs of ordinary carbon steel Q235 steel is 235MPa, while the σs of low alloy structural steel 16Mn is above 360MPa. σs /σb of 40 steel is only 0.43, which is much lower than that of alloy steel. (3) Poor tempering stability Due to poor tempering stability, when tempering carbon steel, it is necessary to adopt a lower tempering temperature in order to ensure higher strength, so that the toughness of steel is low; In order to ensure good toughness, the strength is low at high tempering temperature, so the comprehensive mechanical properties of carbon steel are not high. (4) carbon steel that can't meet the requirements of special properties is often poor in oxidation resistance, corrosion resistance, heat resistance, low temperature resistance, wear resistance and special electromagnetic properties, and can't meet the requirements of special performance. |
