Effect of Ni on the Microstructure and Properties of Stainless Steel for Assisted Fruit Picking Equipment
The effect of nickel element on the microstructure and properties of martensite stainless steel for assisted fruit picking equipment was studied by means of scanning electron microscope(SEM),tensile test,impact test,and hardness test.The results showed that nickel could refine the original size of martensite grain of the test steel about 6 μm during quenching and heating,and reduced the width of martensite flat noodles by about 100 nm;The yield strength and tensile strength of the test steel were increased by about 50 MPa,the impact toughness at room temperature was increased by about 78 J/cm2,the Vickers hardness value was increased by about 27 HV10,which is beneficial for improving the performance of stainless steel used in fruit picking equipment.
