The power input shaft from a cement plant mill failed after approximately 1.5 years in service. Failure was considered premature as the shaft supposedly had a design life of 25 years. Elemental analysis (Table 5.2) would suggest the shaft had been fabricated in a BS 970 817M40 (EN24) heat-treatable steel that had been through-hardened and ...
