Die Science:Guidelines for forming high-strength materialSix Common Characteristics. When compared with lower-strength materials, high-strength metals usually have the following traits:Less stretchability and lower n valuesWhile this trait usually is typical, some grades of steel, such as dual-phase, have reasonably good initial stretch characteristics.These steel types achieve their overall high strengths through the process of work hardening.
Difference Between Hot and Cold Rolled Steel Metal Sep 11, 2014 · Hot Rolled Steel Hot rolling is a mill process which involves rolling the steel at a high temperature (typically at a temperature over 1700° F), which is above the steels recrystallization temperature. When steel is above the recrystallization temperature, it can be shaped and formed easily, and the steel can be made in much larger sizes.
Sep 11, 2014 · The differences between hot rolled steel and cold rolled steel relates to the way these metals are processed at the mill, and not the product specification or grade. Hot rolled steel involves rolling the steel at high temperatures, where cold rolled steel is processed further in cold reduction mills where the material is cooled followed by
Forming high-strength materials - The Fabricator - Metal If the steel in this example had a 120,000-PSI yield strength, the yield diameter would equal 31-1/4 in., so high-yield-strength products also require tighter bends and more work and power. Coil set typically can be corrected by applying a small reverse bend, which can be performed by a spread-center flattener.
HOT ROLLED STEEL HOT ROLLED STEEL PROPERTIES ON In the hot rolling, the metal plasticity gets high, with lower resistance to deformation, which is hugely decrease the cost of energy for metal deformation. And it can improve the processing property of metal and alloy. Because hot rolled steel was made by rolling with high temperature, so its strength is not high.

Steel Metal Stamping. Well known for its strength, steel is the most common metal alloy in the world, produced in one form or another since 1400 BC. In its simplest form, steel consists primarily of iron and contains varying amounts of carbon. Carbon is the most cost-effective way to alloy iron, solidifying the structures in it and strengthening the resulting metal.
Steel Sheets for Highly Productive Hot Stampinghot-stamped, super-high strength parts to automobile bodies. Hot stamping is a technology that can solve the problems associated with high-strength steel sheet, e.g., an increased forming load and deterioration of dimensional accuracy; however, the method has suffered from low press productivity and limitation in the shapes of parts.
