Effect of quenching temperature on microstructure and properties of 0Cr13Ni8Mo2Al stainless steel for piano stringer
Abstract
T Stainless steel, as a common material for piano stringer, has the advantages of high strength and good toughness. 0Cr13Ni8Mo2Al stainless steel meets the strength and enhances the toughness of the piano string machine, so it is a relatively successful golf club material. A new type of 0Cr13Ni8Mo2Al stainless steel was studied. The microstructure, hardness and tensile properties of the stainless steel after quenching treatment were studied. The effects of quenching treatment on the microstructure, hardness, strength, plasticity and toughness of the alloy were clarified. The experimental results show that the best quenching process of stainless steel is 515 °C, the hardness is the highest 45.7 HRC, the tensile strength is the highest 145 MPa and the elongation is 13.8 %. This study has a certain guiding role in the development of piano stringing machine materials.
