Sheet steel that undergoes acid pickling will oxidize (rust) when exposed to atmospheric conditions of moderately high humidity. For this reason, a thin film of oil or similar waterproof coating is applied to create a barrier to moisture in the air. This oil film must later be removed for many fabrication, plating or painting processes.
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 ...
Flame cleaning, also known as flame gouging, [1] is the process of cleaning a structural steel surface by passing an intensely hot oxyacetylene flame over it. Mill scale and rust are removed by the reducing effect of the flame and the action of the heat, leaving the surface in a condition suitable for wire brushing and painting.
A phosphate coating is usually obtained by applying to the steel part a dilute solution of phosphoric acid, possibly with soluble iron, zinc, and/or manganese salts. The solution may be applied by sponging, spraying, or immersion. [6] Phosphate conversion coatings can also be used on aluminium, zinc, cadmium, silver and tin. [7] [8]
Studies have shown that perforated metals help reduce sound levels. [4] Studies have shown that having buildings use perforated metal sheets in front of their façade can bring in one study 29% energy savings (HVAC + Lighting estimated consumption in 1 year) and in the second one 45% energy savings (heating, ventilation, air conditioning).
The process of hot-dip galvanizing results in a metallurgical bond between zinc and steel, with a series of distinct iron-zinc alloys. The resulting coated steel can be used in much the same way as uncoated. A typical hot-dip galvanizing line operates as follows: [2] Steel is cleaned using a caustic solution. This removes oil/grease, dirt, and ...
Angle plates are made from high quality material (generally spheroidal cast iron) that has been stabilized to prevent further movement or distortion. Slotted holes or "T" bolt slots are machined into the surfaces to enable the secure attachment or clamping of workpieces to the plate, and the plate to the worktable.
A cleaning rod is a firearm maintenance tool that can be used to clean the inside (bore) of a gun's barrel, and is made in different sizes for use on different barrel lengths, calibers and gauges. It is a sturdy, long, thin, straight rod typically made of metal, rigid plastic or carbon fiber , and usually has a handle at one end for gripping ...
