Abstract

The invention discloses a high-chrome abrasion-resistant and impact-resistant alloy for a motor rotor. The high-chrome abrasion-resistant and impact-resistant alloy for the motor rotor comprises the following components in percentage by mass: more than 2.8% and less than 3.2% of C, more than 0.4% and less than 0.8% of Si, more than 0.3% and less than 0.5% of Mn, more than 11% and less than 14% of Cr, more than 0.8% and less than 1.4% of Al, more than 0.02% and less than 0.06% of Mo, more than 0.001% and less than 0.006% of P, more than 0.001% and less than 0.008% of S and the balance of Fe and inevitable impurities. The high-chrome abrasion-resistant and impact-resistant alloy for the motor rotor is good in abrasion-resistance, good in thermal stability and long in service life.

Description

technical field [0001] The invention relates to the field of alloys, in particular to a high-chromium wear-resistant and impact-resistant alloy for motor rotors. Background technique [0002] The motor rotor is also the rotating part in the motor. The motor consists of two parts, the rotor and the stator, which are used to realize the conversion of electrical energy and mechanical energy and mechanical energy and electrical energy. The motor rotor is divided into a motor rotor and a generator rotor. However, the wear resistance and impact resistance of the motor rotor alloys in the prior art cannot meet the needs in the actual use process, so it is urgent to develop a high chromium wear resistance and impact resistance alloy for motor rotors to solve the problems in the prior art. Contents of the invention [0003] In order to solve the technical problems existing in the background technology, the present invention proposes a high-chromium wear-resistant and impact-resis...
