Longitudinal @ -40 FAstraWear 500f is a water tempered martensitic steel, with 500 BHN ( HRC), typical hardness and resistant to wear from very severe abrasion. Its mechanical properties, high wear resistance, hardness, and strength make AstraWear 500f steel ideal for use in applications requiring resistance to sliding abrasion and where 400 BHN steels do not provide a long enough service with conventional steels, like A572-50 (S355), AstraWear 500f offers an improvement of up to 5 times the equipment lifespan. Consequently, it allows for a significant reduction in the required design 500f steel is especially suited for applications in quarries, construction, mines, cement plants, and the iron and steel industry, among : The data contained in this document is accurate at time of printing, and intended for use as a general guide.
