origin experimental data of Study on mechanical properties and microstructure of 30CrMnSiA ultrastrong low alloy wear-resistant steel

This work was devoted to preparing a kind of 30CrMnSiAhigh strength and low alloy wear-resistant steel suitable for excavator bucket teeth. Through the forging, quenching and tempering process, the ultrastrong low alloy steel with good toughness and wear resistance has been successfully prepared. The yield strength, tensile strength, elongation and hardness of the ultrastrong steel reached up to1700MPa, 1960MPa, 7% and 563HV, respectively. OM, SEM and TEM were used to observe the microstructures of the ultrastrong steel, and it was found that the microstructures of the steel was fineand dense due to the forging process.
