Tool Steel
Tool steel refers to a variety of carbon and alloy steels that are particularly well-suited to be made into tools. Their suitability comes from their distinctive hardness, resistance to abrasion, their ability to hold a cutting edge, and/or their resistance to deformation at elevated temperatures (red-hardness). Tool steel is generally used in a heat-treated state. Many high carbon tool steels are also more resistant to corrosion due to their higher ratios of elements such as vanadium and niobium.

Famous quotes containing the words steel and/or tool:
“Cold eyes ... steel grey, rather small, not unpleasant in good-humour, diabolic in a passion, but worst when a little suspicious; then they watch you as though you were a young rattle-snake, to be killed when convenient.”
—Henry Brooks Adams (1838–1918)
“Is it not possible that an individual may be right and a government wrong? Are laws to be enforced simply because they were made? or declared by any number of men to be good, if they are not good? Is there any necessity for a man’s being a tool to perform a deed of which his better nature disapproves?”
—Henry David Thoreau (1817–1862)
