Heat Treated Plates - The Three Ws

Heated treated plates are a steel product that is specially treated to high temperatures to make it wear resistant and more durable. Such plates are most often manufactured from medium alloys or hard alloys.
The three major steps involved in the heat treatment procedure typically include the following:
The steel is heated to a high critical temperature, which causes its carbon atoms to migrate to the center.
The steel is then allowed to slowly cool, or water quench, during which the carbon is forced back out. The slowness of this phase results in durable steel rather than the brittle steel that is produced when it is cooled too quickly by immersing it in water or oil.
The steel is then reheated. During this phase of the process, which is referred to as tempering, the desired end hardness is achieved.
During this procedural, steel plates of up to 40 feet long and 8 feet wide can be tempered and quenched as outlined above in special furnaces. The furnace-quenching facilities that take on this process can handle everything from angles and channels to wide flange beams.
A select few suppliers use armor plating as their core product. Such in-house heat treat lines are specifically designed to supply light gauge armor plates to Mil DTL 46100 Rev E, Mil DTL 12560 Rev J, and Mil DTL 46177 Rev C tempering furnace table ready for processing.
Why are plates heat treated?
Customers who require the flattest possible plates in the industry without resorting to mechanized flattening should select a service provider that wields rigid process controls over their process. Why is choosing a steel partner who takes such proactive measures so important? Because when heat treated plates are mechanically flattened, the process can result in uneven internal and residual stresses. As a result, when the plate is cut, it tends to warp. In turn, potential costly damage to the processing equipment can occur.
For what and where are heat treated plates used?
Heat treated plates are found in a wide range of industrial applications. When it is made of high tensile fine grain structural steel, heat treated plating is used for welded steel structures. That means the product will be found in manufacturing industries where vehicles and mobile crates are the end product. This type of steel is also used to make mining equipment, pressure tanks and pressure pipes as well as ballistic steel for armoring.
In addition, because they have greater toughness and wear resistance then lower carbon grades, heat treated plates are used to make jigs, strippers, molds, couplings, sprockets, ejectors, fixtures, gears, valves, tie rods, brakes dies and bolsters, just to name a few of their end products. Machinery parts and components of all sorts also employ the technology.
A company in Paris, France also recently announced that it would be producing advanced heat treated plates for the aerospace and general engineering markets, both of which make wide use of the technology.
