shear steel
Definition
- Noun:
- A type of steel: "shear steel" refers to a high-carbon steel that has been processed through a specific method (often blister steel that is further refined by shearing, welding, and forging) to produce a material with superior hardness and edge retention. It is traditionally used for making cutting tools like shears, knives, and scissors.
Usage Examples
- (The steel is specially made for cutting tools.)
- (The steel's quality is prized for its long-lasting sharpness.)
Advanced Usage
- "shear steel" in metallurgy: In historical contexts, shear steel is a stage in the production of crucible steel, where blister steel is cut (sheared), stacked, and forge-welded to homogenize the carbon content and eliminate impurities.
- The process of making shear steel involves repeated heating and hammering to refine the metal. (The method improves the steel's uniformity.)
Variants and Related Words
Shear (n): a cutting tool or machine that cuts material by applying a shearing force.
- The gardener used garden shears to trim the hedges. (The tool is related to the function of the steel.)
Steel (n): a hard, strong alloy of iron and carbon, used as a base material.
- Steel is essential for constructing buildings and machinery. (The base material for shear steel.)
Synonyms
- High-carbon steel: steel with a higher carbon content (typically 0.6%–1.5%) that can be hardened and is used for cutting tools.
- Blister steel: a precursor to shear steel, produced by carburizing iron bars in a furnace, which results in a blistered surface.
