Effect of heat treatment process on impact - steel plates

In order to study the hardness and impact properties of GBT 11251 30CrMnSi steel with different quenching processes,two heat treatment processes were selected to study.First process is the conventional quenching process,the quenching temperature is 910 ,tempering temperature according to 230,330,430,530 and 430 .GB/T 11251 20Cr hot rolled structure steel plates - BBN SteelGB/T 11251 20Cr hot rolled structure steel plates can also be used in quenching and tempering condition to manufacture parts with larger working speed and medium impact load.GB/T 11251 20Cr hot rolled structure steel plates can also be used as low-carbon steel for martensitic quenching,which further increases yield strength and tensile GB/T 11251 20Cr hot rolled structure steel plates - Bebon GB/T 11251 20Cr hot rolled structure steel plates ,GB/T 11251 20Cr hot rolled structure steel plates are widely used to manufacture carburized parts (oil quenching) that have high requirements for core strength,bearing surface wear,section below 30mm,shape is complex and load is small.For example machine transmission gear,gear shaft,cam,worm,piston pin,claw clutch.

GB/T 11251 30CrMnSiA alloy steel plates - BEBON steel

GB/T 11251 30CrMnSiA alloy steel plates are medium carbon tempered steel with high strength and poor welding performance.After quenching and tempering,30CrMnSiA alloy steel plates have high strength and toughness and good hardenability.GB/T 11251 30CrMnSiA alloy steel plates - BEBON steelGB/T 11251 30CrMnSiA alloy steel plates are medium carbon tempered steel with high strength and poor welding performance.After quenching and tempering,30CrMnSiA alloy steel plates have high strength and toughness and good hardenability.GB/T 11251 30CrMnSiA alloy steelGB/T 11251 30CrMnSiA hot rolled structure steel plates GB/T 11251 30CrMnSiA hot rolled structure steel plates are medium carbon tempered steel with high strength and poor welding performance.After quenching and tempering,30CrMnSiA alloy steel plates have high strength and toughness and good hardenability.GB/T 11251 30CrMnSiA hot rolled structure steel plates chemical composition:

GB/T 11251 35CrMnSiA hot rolled structure steel plates

But at the same time,its corrosion resistance and oxidation resistance is low.Therefore,GB/T 11251 35CrMnSiA hot rolled structure steel plates are usually used after low temperature tempering or equal temperature quenching.GB/T 11251 35CrMnSiA hot rolled structure steel plates chemical composition:GB/T 11251 40Cr hot rolled structure steel plates - BBN SteelGB/T 11251 40Cr hot rolled structure steel plate is also suitable for cyanidation and high frequency quenching in addition to quenching and tempering treatment.The cutting performance is better when the hardness is from HB174 to 229,the relative machinability is 60%.GB/T 11251 40Cr hot rolled structure steel plates chemical composition:GB/T 11251 40Cr hot rolled structure steel plates - Bebon The hardenability of the steel is good.GB/T 11251 40Cr hot rolled structure steel plate is also suitable for cyanidation and high frequency quenching in addition to quenching and tempering treatment.The cutting performance is better when the hardness is from HB174 to 229,the relative machinability is 60%.
