Across
- 3. - Removing some of the brittleness and hardness from steel after it has been hardened. This is done by reheating then cooling it.
- 5. - Heat-treating metal to produce its softest possible working state.
- 6. - A process in which a fast revolving sheet of ductile metal is shaped over a wood or metal former. Alloy kitchenware is produced this way,
- 8. - Producing maximum hardness in carbon steel by heating it to bright cherry red then quenching it in water, brine or oil.
- 10. - Shaping hot metal by hammering
Down
- 1. - Heat-treating steel to improve its corrosion resistance. The metal is heated to create a very thin oxide skin, then quenched in oil
- 2. - Forming sheet metal to shape with a die mould under pressure
- 4. - Forcing materials through holes to produce bars, sections or tubes wire
- 7. - Production of metal shapes by pouring molten metal into moulds
- 9. - Pulling ductile metals through holes in a plate to produce unique cross-sections and lateral shapes.
