Unformatted text preview: 2. The reliability factor for 99% reliability is 0.21, and the radial load of 2 kN does not need correcting, as the axial load is less than 35% of it. Hence the life is estimated as 0.21 x 90 (6.1/2) 3.33 = 774.78 million revolutions. 3. 0.10%. 4. It turns to martensite. 5. 730 o C 6. Case hardening is a hardening of [ surface] . The [ nitriding] is a common case hardening process. Flame heat treatment can be applied to low carbon steels [ false] ....
