Hammer Forging
The mechanical forming of metal by means of a hammer. The action of the hammer is that of an instantaneous application of pressure in the form of a sudden blow.

Hardness
The ability of a metal to resist penetration, defined in terms of the measurement (Brinell, Rockwell, etc.)

Hardness Test
A test used to determine the relative resistance to indentation or displacement of metals by pressure, or by resistance to abrasion. Common methods of testing include Brinell, Rockwell, and Vickers tests.

Heat Treatment
An operation or combination of operations involving the heating and cooling of a metal or alloy in the solid state to attain certain desired microstructure or properties.

Hollow Forging
The process of producing circular hollow, tube-like parts by expanding or lengthening the hot workpiece over a mandrel.

Hot chamber machines
Die casting machines which have the plunger, gooseneck (metal pressure chamber) immersed in molten metal in the holding furnace.

Hot short
Term used to describe an alloy which is brittle or lacks strength at elevated temperatures.

Hub
Part that has been upset forged using loose tools. This process produces a shape with a smaller diameter projection from either one or both sides of the major diameter of the part.
