Performance characteristics
High carbon content: Compared with Q235B, 55Q has a higher carbon content, which gives it higher hardness and wear resistance.
Excellent mechanical properties: 55Q steel rails have high brittleness, toughness, tensile strength, and impact strength, making them suitable for use in harsh mining environments.
Diverse specifications: 55Q steel rails come in various sizes, such as 24kg/m, 22kg/m, 18kg/m, etc., to meet the transportation needs of different mining areas.
