There also may be cases when you need to surface hardened the shaft. An example might be if the shaft is also the journal for a bearing. In these cases you could use the following materials ANSI 1020, 4320, 4820, and 8620. If you choose to use a cold drawn steel. You will normally need to keep the largest diameter of the shaft under 3 inches.

TORSION OF SHAFTS. When a cylindrical shaft is subjected to equal and opposite couples at the ends, either it will be in equilibrium or it will rotate at a uniform rate. In either case, it is subjected to torsion and the stresses set up by every crosssection are shear stresses. At any point in the crosssection of a shaft, there is a state of ...

The grout is normally a watercement mixture applied at high pressure of up to 800 psi. The grouting is typically performed after the concrete has achieved a compressive strength of at least 2500 psi. If several shafts need to be grouted, the project can be delayed until it is convenient to perform the operation on several shafts together.
