Abstract

The invention discloses a high-chromium high-strength impact resistant alloy used for a water pump motor. The high-chromium high-strength impact resistant alloy used for the water pump motor is composed of, by mass, 1.3-1.6% of C, 1.8-2.5% of Si, 0.2-0.6% of Mn, 10-15% of Cr, 0.3-1.6% of Cu, 0.2-0.5% of Mo, 0.02-0.05% of P, 0.01-0.04% of S, 0.025-0.14% of Re and the balance Fe and inevitable impurities. By reasonably selecting components of the high-chromium alloy, the abrasion resistance and the corrosion resistance of an abrasion resisting part are improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to the field of alloys, in particular to a high-chromium high-strength impact-resistant alloy for water pump motors. Background technique [0002] According to the structural classification, the water pump motor should be divided into horizontal motor and vertical motor. Because the working characteristics of the water pump are relatively small starting torque, relatively small starting frequency, and relatively long continuous running time, the majority of water pump motors are asynchronous motors or synchronous motors with squirrel cage rotors. [0003] The strength, impact resistance and corrosion resistance of the alloy used in the water pump motor in the prior art cannot meet the needs in the actual use process, so it is urgent to develop a high-chromium high-strength impact-resistant alloy for the water pump motor to solve the existing problems. problems in technology. Contents of the invention [0004] In order to solve...
