Our steels have been widely applied to many industries and fields, such as the construction industry, shipbuilding industry, pressure vessels and boilers, oil and gas, bridge construction, offshore platforms, stamping cold forming,etc.
Cold rolling is the most common method of work hardening. This involves the metal being passed through pairs of rollers to reduce its thickness or to make the thickness uniform. As it moves through the rollers and is compressed, the metal grains are deformed.Author Terence Bell
Hot Work Tool Steel. Hot working tool steel to make iron and nonferrous metals as well as hot forming of the workpiece at high temperature of the alloy derivative. They are used in the manufacture of pressure die casting, extrusion and forging, as well as in the process of pipe and glass manufacturing.
There are six groups of tool steel water-hardening, cold-work tool steels, shock-resisting, high-speed, hot-work, and special purpose/plastic mold tools steel. The choice of group to select depends on, cost, working temperature, required surface hardness, strength, shock …
Hot work and cold work permits are both attempts at preventing uncontrolled fires. Hot work involves working with a source of ignition, like sparks or an open flame, in an environment with potentially flammable or explosive atmosphere. Cold work refers to a working situation in which there are no sources of ignition present.

The O7 steel has the best wear resistance of the series but the lowest hardenability, both properties being linked with the high tungsten addition. ... Table 1 Cold work tool steel types, according to the US UNS, AISI and SAE classification. Classification of principal types.
Tool Steel is divided into these six groups water-hardening, cold-work, shock-resisting, high-speed, hot-work, and special purpose. The determination of a choice from the group will depend on; the cost effectiveness, working temperature, required surface hardness, strength, shock resistance, and toughness requirement.

This is a technique commonly used in non-brittle metals that have remarkably elevated melting points. A number of polymers can also be strengthened using this method. However, cold-worked areas in metal are more prone to corrosion due to heightened dislocation concentration. Cold working is also known as work …
Effects of Cold Work Stress-strain curves for a material with progressively increasing cold work ... --cold work •Hnge (iat annealing) can reduce dislocation density and increase grain size. Summary. ... • Steel plate at 700 °C with geometry shown 13
could I cold work brass or copper the same way I hot work steel? I think copper esp. would look great as demo models ... copper and brass have a better response when annealed and cold forged rather than hot forged. To anneal them you don't have to take them to red hot temperatures. It depends on the alloy, but it can go from 400 to 700°C. ...
Cold and Hot Working Review of Materials. Plastic deformation which is carried out in a temperature region and over a time interval such that the strain hardening is not relieved is called cold work. Considerable knowledge on the structure of the cold-worked state has been obtained.
A hot-work tool steel's functionality is defined by its chemical composition, the technology applied during production and by the ensuing heat treatment. In general, hot-work steels are of the medium and high-alloy type and most of them has relatively low carbon content (0.25 to 0.6%).
Hot & Cold Working and the Rolling Process . Hot & Cold Working ... When the processing temperature of the mechanical deformation of steel is above the recrystallization temperature, the process is termed as hot working; otherwise, it is cold working. ... Steels that are cold rolled become work hardened and annealing is required in order to ...
In ASTM A681-199 include the D6 Cold work tool steel, UNS T30403, SAE D6 steel, It is standard specification of cold work tool steels for cold work tool, mould, die application, such as hot rolling or hot forging steels or cold drawn steel grade.
The steel bars we machine are typically cold drawn (cold worked). Suppliers use cold work when cold drawing a bar from hot roll to make it more machinable. No heat is added to a cold work process, and no chip is removed in the process of moving the metal into shape.

All of these factors will help you decide which type of rolled steel will be best for your project. Larger sized materials that need to be in more distinct shapes should be created with the hot rolled steel process. Smaller products that need to be more durable and tolerant, should be created with the cold rolled steel process.
