Temper:

The state of a metal relating to its hardness or toughness produced by thermal treatment, heat treatment and quench, or cold working to bring the metal to its specified consistency.

Tempered Spring Steel Strip:

Any medium or high carbon strip steel of spring quality which has been hardened and tempered to meet specifications. When polished, it is also called “clock spring steel”; it is been ground and polished with its edges dressed.

Tempering:

A process of reheating quench-hardened or normalized steel to a temperature below the transformation range and then cooling at any rate desired. The primary purpose of tempering is to impart a degree of plasticity or toughness to the steel to alleviate the brittleness of its martensite.

Tensile Strength:

The breaking strength of a material when subjected to a stretching force.

Tin:

An element known for its high malleability and ductility, but low tensile strength. It is mainly used as a coating on steel in tin plate and in alloys.

Titanium:

An element known for its malleability and ductility when pure, and high strength and good corrosion resistance in alloys.

Tool Steel:

Any high carbon or alloy steel capable of being suitable tempered for use in the manufacture of tools.

Toughness:

Property of resisting fracture or distortion. Usually measured by impact test, high impact values indicating high toughness.

Tungsten:

An element known for its high tensile strength, ductility, and malleability. It promotes hardness and strength at elevated temperatures.

Tungsten Carbide:

A compound of tungsten and carbon, it is frequently imbedded in soft metals, such as cobalt.
