Bending Basics: The fundamentals of heavy bending

 · In steel between 0.5 and 0.8 in. thick, grade 350 and 400 may have a minimum bend radius of 2.5 times the material thickness when transverse bending, while longitudinal bending may require a minimum bend radius that''s 3.75 times the material thickness. And between 0.8 and 2 in. thick, you likely will need to hot-form.

Steel Temperatures – Hot Rolled, Cold Rolled, and Cold ...

On top of that, there''s the method used for producing and forming the steel. Not to be confused with steel grade or specs, steel processing offers two options: hot rolled and cold rolled. Heat, of course, is used in all steel manufacturing. Hot rolling and cold rolling simply refer to how it''s processed at the end.

When Cold Forming Threads Makes Sense | Modern Machine …

 · Tapping via cold forming is appropriate for materials with tensile strength less than 1,200 N/mm2 and fracture strain of 5 percent. As a rule of thumb, if a continuous chip is created when drilling, then the material is likely a good candidate for cold forming the threads. However, suitable materials react to cold forming in different ways.

Cutting Taps vs. Forming Taps

Forming taps are limited in use to those materials malleable enough for the process, like non-ferrous metals, aluminum, and soft steel. They also produce a thread-form that is slightly different in appearance when compared to thread produced by a cutting tool.

High Strength Low Alloy Steel

BenDinG and FoRMinG — This steel, if not extremely cold, will take a 90º bend to a reasonable radius in thicknesses up to about 3/8" without fracture, providing it is bent slowly (by degree) until the forming has been completed. For more difficult forming and for all forming of heavier gauges, it should be heated and formed while hot.
