2. Slotted angle - Wikipedia

   en.wikipedia.org/wiki/Slotted_angle

   Slotted angle (also sometimes referred to as slotted angle iron) is a system of reusable metal strips used to construct shelving, frames, work benches, equipment stands and other structures. The name derives, first, from the use of elongated slots punched into the metal at uniform intervals to enable assembly of structures fixed with nuts and ...

3. Ferroaluminum - Wikipedia

   en.wikipedia.org/wiki/Ferroaluminum

   The presence of iron in aluminum helps in the decrease of casting defects, improves tensile, yield, hardness, and maintains strength at high temperatures. [3] The first recorded usage of the word "ferroaluminum" was in 1887. [4] [5] Ferroaluminum can also be nitrided, as the aluminium bonds well with the nitrogen forming a hard case. The ...

4. Bar stock - Wikipedia

   en.wikipedia.org/wiki/Bar_stock

   A bar is characterised by an "enclosed invariant convex cross-section", meaning that pipes, angle stock and objects with varying diameter are not considered bar stock. Bar stock is commonly processed by a sequence of sawing , turning , milling , drilling and grinding to produce a final product, often vastly different from the original stock.

5. Structural steel - Wikipedia

   en.wikipedia.org/wiki/Structural_steel

   The austenizing temperature, the temperature where a steel transforms to an austenite crystal structure, for steel starts at 900 °C (1,650 °F) for pure iron, then, as more carbon is added, the temperature falls to a minimum 724 °C (1,335 °F) for eutectic steel (steel with only .83% by weight of carbon in it).

7. Shear (sheet metal) - Wikipedia

   en.wikipedia.org/wiki/Shear_(sheet_metal)

   Setting the blade on an angle decreases the amount of force required, but increases the stroke. A 5-degree shear angle decreases the force by about 20% [citation needed]. The amount of energy used is still the same. The moving blade may also be inclined 0.5 to 2.5°, called the rake angle, to keep the material from becoming wedged between the ...
