61SiCr7 (1.7108) is a widely used silicon manganese spring steel, slightly higher than 55SI2MN. Suitable for the railway vehicle and automobile tractor industries, it can produce a large number of springs or screw springs, a large number of springs or screw springs, or a diameter of less than 30mm. It is also suitable for heat resistant springs with non corrosive media at production temperatures below 250 °. And large important volume springs that work under high stress.
