Chrome plating (less commonly chromium plating) is a technique of electroplating a thin layer of chromium onto a metal object. A chrome plated part is called chrome, or is said to have been chromed. The chromium layer can be decorative, provide corrosion resistance, facilitate cleaning, and increase surface hardness. Sometimes a less expensive ...
A set of metric spanners or wrenches, open at one end and box/ring at the other. These are commonly known as “combination” spanners. A wrench or spanner is a tool used to provide grip and mechanical advantage in applying torque to turn objects—usually rotary fasteners, such as nuts and bolts—or keep them from turning.
The high shock resistance and good hardenability are provided by chromium-tungsten, silicon-molybdenum, silicon-manganese alloying. Shock-resisting group tool steels (S) are designed to resist shock at both low and high temperatures. A low carbon content is required for the necessary toughness (approximately 0.5% carbon).
An adjustable spanner (UK and most other English-speaking countries), also called a shifting spanner (Australia and New Zealand) [1] or adjustable wrench (US and Canada), [a] is any of various styles of spanner (wrench) with a movable jaw, allowing it to be used with different sizes of fastener head (nut, bolt, etc.) rather than just one fastener size, as with a conventional fixed spanner.
Chromium is a chemical element; it has symbol Cr and atomic number 24. It is the first element in group 6. It is a steely-grey, lustrous, hard, ...
Chromium–vanadium steel (symbol Cr-V or CrV; 6000-series SAE steel grades, often marketed as "Boss AA" [1]) is a group of steel alloys incorporating carbon (0.50%), ...
