When using stainless steel, there are many options on the finish the customer can choose. Starting with the standard 2B mill-finish ranging all the way to a mirrored, or #8 finish. There are over 50 stainless steel grades. All stainless steel grades contain a minimum of 10.5% chromium . Additional chromium and other elements are added to improve corrosion and heat resistance, and to enhance or improve mechanical properties and fabricating characteristics. The alloy composition as well as material thickness, bend radius and bend angle are all important factors we take into consideration when calculating the bending force necessary to avoid a “springback” of the stainless steel to its original, straight shape. .
A variety of methods can be used for bending stainless steel. A large radius bend would be rolled on a section bender (also known as a profile bender or angle roller); a bend requiring a tight radius would be rolled on a rotary-draw bender through a technique called mandrel bending; a stainless steel tube or pipe requiring a bend with minimal deformation in wall thickness or ovality would be rolled using the induction bending process; and helical spiral bending can be done with every stainless steel section using a CNC 4 roll bender. Chicago Metal Rolled Products has in-house capabilities for all these methods.
Frequently used for handrails, bollards, ladders, staircases and art sculptures, rolled stainless steel is now quite often replacing concrete in structural design – including swimming pools. Fermentation tanks for wine making and craft beers are on the rise as well as other pharmaceutical and food grade applications including ss tubing as a ducting system to convey fluids.
Chicago Metal Rolled Products has spent decades perfecting the art and craft of bending stainless steel. This has become a value-added service for customers seeking a polished finish. It is far easier, faster and cost efficient to have the material polished prior to the bending process while it is still straight. Through experience and proprietary tooling we produce curved stainless steel parts with little to no scratching, carbon-transfer or carbon contamination, thus reducing the amount of fabrication time needed after bending. Typically only minor touch-up work is necessary. Our machine shop is also equipped to cut, drill, bevel, punch and weld any segment either before or after bending. Customers request our machined-bevel weld prep on curved stainless steel cylinder projects to enhance the efficiency of their welding operation and minimize rework expense.
