Cold Rolled Mild Steel Strip

We stock a large range of mild steels which can be slit to the customers requirement. We also have a wide range of excess offcuts which may be of interest.

The company adopts a progressive approach to incorporating new technology into production processes. A newly installed Slitting line, for example, is capable of offering fine slitting tolerances and minimum edge bow requirements. Detailed inspection and testing to customer requirements are maintained, and test certificates are supplied to British Standards.

Mild and high carbon steels are defined by their carbon content which governs both their basic mechanical properties of hardness and tensile strength and their ability to develop enhanced properties within various processes such as cold forming or heat treatment.

Mild steels are low carbon variants with carbon levels of up to 0.12% as defined in BS 1449: part 1 1991, with such grades as CS1, CS2, CS3 and CS4. Such Mild Steel Strip has relatively low tensile strength but good ductility levels which facilitate the production of complicated component shapes where required and even allowing deep pressing processes to be carried out.

Mild Steel Strip has a high number of different conditions in which it can be supplied ranging from fully annealed to extra hard rolled, these being delineated by defined hardness levels with annealed at 105 VPN max (equivalent to 370 N/mm² tensile strength) and extra hard rolled as high as 210 VPN plus, (670 N/mm² tensile strength) their intrinsic hardness levels being changeable by cold deformation. This cold deformation is normally carried out by a rolling process. However, it is also possible to generate further property changes by case hardening these steels using such techniques as case-carburizing, nitriding and carbo-nitriding. These techniques involve diffusing carbon and nitrogen into the surface of the components by various combinations of gaseous or solid atmospheres and appropriate temperatures. Case hardening can raise surface hardness levels considerably and provide significantly enhanced wear/abrasion resistance properties.

These surface-hardening processes can result in an attractive and utilitarian combination of high surface hardness and internal toughness or shock resistance. Consequently, Mild Steel Strip offers a highly versatile package of materials, which find extremely wide usage in both domestic and industrial component manufacture. Such components are also often required with surface coatings, either for some corrosion resistance or even cosmetic appearance and coatings such as zinc - galvanizing, tin, aluminum, nickel or copper coating or even chromium plating, can be applied.
