Abstract

The invention discloses steel for high-speed train wheels. The chemical composition of the steel for wheels consists of the following components in percentage by weight: 0.46-0.50% of C, 0.4-0.6% of Si, 2.1-2.3% of Mn, less than or equal to 0.015% of P, less than or equal to 0.010% of S, 0.004-0.006% of B, 2.4-2.6% of Ni, 1.2-1.6% of Cr and the balance of iron and unavoidable impurities.

Description

technical field [0001] The invention relates to the technical field of iron and steel metallurgy, in particular to steel for high-speed train wheels. Background technique [0002] From the perspective of the evolution process of the standards for domestic railway passenger car wheels, the national standard "Rolled Steel Rolled Wheels for Railways" (GB8601-88) was promulgated and implemented in 1988, which is applicable to railway passenger cars with a running speed of ≤80km / h before the speed increase of my country's railways Wheels for vehicles; "Technical Conditions for Railway Express Passenger Car Rolling Steel Integral Wheels" (TB / T2708-1996) promulgated in 1996 replaced GB8601-88, which is mainly applicable to railway passenger cars with a running speed of ≤160km / h after the speed increase of my country's railways wheel. The composition requirements of conventional CL60 wheel steel in these two standards are consistent, but TB / T2708-1996 requires that the plasticity of ...
