    en.wikipedia.org/wiki/Husky_(tool_brand)

    Husky is a line of hand tools, pneumatic tools, and tool storage products. Though founded in 1924, it is now best known as the house brand of The Home Depot, where it is exclusively sold. Its hand tools are manufactured for Home Depot by Western Forge, Apex Tool Group, and Iron Bridge Tools. [1] Its slogan is "The toughest name in tools."

  3. Tempering (metallurgy) - Wikipedia

    en.wikipedia.org/wiki/Tempering_(metallurgy)

    Tempering is a process of heat treating, which is used to increase the toughness of iron-based alloys. Tempering is usually performed after hardening, to reduce some of the excess hardness, and is done by heating the metal to some temperature below the critical point for a certain period of time, then allowing it to cool in still air. The exact ...

    en.wikipedia.org/wiki/Water_heating

    A tempering valve mixes enough cold water with the hot water from the heater to keep the outgoing water temperature fixed at a more moderate temperature, often set to 50 °C (122 °F). Without a tempering valve, reduction of the water heater's setpoint temperature is the most direct way to reduce scalding.

    These are single Outlet Thermostatic Mixing Valves, often called "thermostatic faucets", "thermostat taps" or "thermostat valves". Designed for single point applications, such as individual showering, hand wash basin mixers, bath or tub fillers; High level protection against scalding and thermal shock

  6. Differential heat treatment - Wikipedia

    en.wikipedia.org/wiki/Differential_heat_treatment

    Differential tempering (also called graded tempering, selective tempering or local tempering) is the inverse of differential hardening, to ultimately produce similar results. Differential tempering begins by taking steel that has been uniformly quenched and hardened, and then heating it in localized areas to reduce the hardness.

    640˚F (337˚C), light blue [26] The tempering colors can be used to judge the final properties of the tempered steel. Very hard tools are often tempered in the light to the dark straw range, whereas springs are often tempered to the blue. However, the final hardness of the tempered steel will vary, depending on the composition of the steel.

  8. Furnace (central heating) - Wikipedia

    en.wikipedia.org/wiki/Furnace_(central_heating)

    The pipes would channel the warm air into floor or wall vents inside the home. This method of heating worked because warm air rises. The system was simple, had few controls, a single automatic gas valve, and no blower. These furnaces could be made to work with any fuel simply by adapting the burner area.

  9. Copper tubing - Wikipedia

    en.wikipedia.org/wiki/Copper_tubing

    Soft (or ductile) copper tubing can be bent easily to travel around obstacles in the path of the tubing. While the work hardening of the drawing process used to size the tubing makes the copper hard or rigid, it is carefully annealed to make it soft again; it is, therefore, more expensive to produce than non-annealed, rigid copper tubing.
