61SiCr7 (1.7108) is a widely used silicomanganese 61SiCr7 (1.7108) 61SiCr7 (1.7108), and its elasticity and hardenability are slightly higher than those of 55Si2Mn. It is suitable for the production of flat springs bearing large loads or coil springs with wire diameter less than 30mm in the railway vehicle, automobile and tractor industries, as well as for the production of heat-resistant springs in non corrosive media with working temperature below 250 ºC and large important coiled springs bearing alternating loads and working under high stress.
