Term Definition
Scalping
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.
Scratch
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.
Shape
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.
Sheet
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.
Squareness
Characteristic of having adjacent sides or planes meeting at 90 degrees.
Stabilizing
A thermal treatment to reduce internal stresses in order to promote dimensional and mechanical property stability.
Strain

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

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.
