Term Definition
Mechanical removal of the surface layer from a fabricating ingot or semifinished wrought product so that surface imperfections will not be worked into the finished product.
A sharp linear indentation in the surface of the metal.
Screw Machine Stock
Bar, rod, and wire in certain standard alloys, tempers, sizes and shapes suitable for automatic screw machine applications.
A section produced by such methods as extruding, rolling, drawing, etc., that is long in relation to its cross-sectional dimensions and has a cross section other than that of sheet, plate, rod, bar, tube or wire.
Shear Strength
The maximum stress which the material is capable of sustaining in shear.
A rolled rectangular section of thickness 0.006 through 0.249 inch with sheared, slit or sawed edges.
Solution Heat Treating
Heating an alloy at a suitable temperature for sufficient time to allow soluble constituents to enter into solid solution where they are retained in a super-saturated state after quenching.
Characteristic of having adjacent sides or planes meeting at 90 degrees.
A thermal treatment to reduce internal stresses in order to promote dimensional and mechanical property stability.

Strain Hardening
Modification of a metal structure by cold working resulting in an increase in strength and hardness with loss of ductility.

Stress Relieving
Non-Hardening process that consists of heating a component to a suitable temperature (below austenising temperature) and once fully heated slow cooled without quenching similar to annealing. This process is primarily used to remove residual stress in manufactured components.
