Product Introduction
GB heavy rails mainly have four specifications: 43 50 60 75kg/m. Commonly used materials are U71MN U75V U78CrV and other materials, with a hardness of 26t-HBW and a tensile strength of ≥880MPa (such as U71Mn).
GB heavy rails may differ from other standards in terms of hardness, but heat treatment technology can solve this problem, adjust the hardness of the rails to adapt to different standards, and improve the toughness of heavy rails.
Heat treatment refers to a metal heat processing procedure that uses heat to change the chemical composition and structure of the surface or interior of the material. The heat treatment process generally includes three procedures: heating, insulation and cooling, and sometimes only heating and cooling are involved. These processes are interrelated and performed continuously.
