High Ductility Cold Rolled Steel Overview

High Cold Rolled Ductility Steel derives from highly thin cold rolled sheets or coils able to deform plastically without fracture. Moreover, the material can be bent, stretched, or even formed into different shapes without any possibiility of cracking. Ductility cold rolled steel is direcly applicable when precisions in forming, bending or stamping is necessary.

Uses in Automotive and Trasportation Industry

High cold rolled ductility steel is used for automotive body panels, chassis parts, and other structural components as well as interior fittings. The ability to create tightly toleranced and conformably manufactuered parts is avaiable. The ductility in parts of crash zones or the areas in a vehicle needing energy absorption improves safety by allowing superior deformation.

Uses in Appliances and Consumer Items

Household appliances such as refrigerators, washing machines, and air-conditioning units commonly make use of cold rolled steel sheets for paneled and framed components. The ability to ductably bend, fold, and weld as well as fasten makes the appliances practical. It is known to create visually appealing forms with precise curves and edges.

Uses in Construction & Architectural Panels

In construction, ducts sidings, claddings, roofing panels, and even decorative facades are not uncommon. The preferred materials for facades or decorative panels are cold rolled steel with high ductility because they can be curved or profiled and not crack or become damaged. Most also allow structural and thermal tolerance expansion.

Uses in Electrical & Electronic Enclosures

Mild steel sheets that require precise cutting and folding are regularly used to manufacture electrical cabinets, control boxes, instrument panels, and even server racks. cold rolled steel with high ductility is preferred because it doesn’t crack, and micro fractures do not form in the enclosure during bending or forming, even with sharp radii.

Uses in Industrial Machinery & Components

Many machine parts and frames require custom brackets, covers and even guards. The heavy formability cold steel with high ductility can take, will allow any shape to be made, with little scrap, and little to no chance of failure. Components that can undergo vibration, overload or deformations will have better tolerance to cyclic stress when made of ductile steel.

Benefits & Key Considerations

The steel can endure tighter bend radii and traverse more forming operations because of its ductility.

• Improved toughness: The material is less susceptible to cracking, particularly during stamping or deep drawing operations.
• Surface finish & tolerances: Cold rolling is able to achieve closer thickness tolerances which is favorable for cosmetic panels or whenever better thickness control.
• Cost tradeoffs: High ductility is also achievable but may warrant excessive alloy management, annealing, or extra process steps which clearly will increase the cost beyond standard cold rolled.
• Coating Compatibility: After forming you can coat, galvanize, or paint. It is critical that the ductile cold rolled substrate be compatible to the finishing processes that follow.

Based on Rarlon Steel’s catalog, you may now provide your clients with cold rolled steel plates and sheets or coils which have clean surfaces and favorable mechanical properties from your Carbon Steel Products line.

When promoting your products, you can also state that cold rolled steel with high ductility can endure additional demanding forming and finishing processes, which is a distinct advantage.
