Low carbon unalloyed steel used for tubing that is relatively easy to form compared to alloy steels, high-carbon steels, and stainless steels. Aluminum-bronze mandrel and wiper tooling is usually recommended for working with mild steel tubing. Hard-chromed mandrel and untreated steel wiper tooling is sometimes preferred because of longer tool-life; however, extended tool-life with these materials is dependent upon continuous and heavy lubrication of the tubing material and tooling surfaces.

A complete guide to the principles of the 4-Step set-up for tube-bending tools
This is a printable handbook showing how to implement in four standardized steps the “forward mandrel” set-up for rotary-draw tube-bending machines and establish process control over the so-called black art. The procedure is based upon the guiding principle that the tools make the bend and takes advantage of the inserted design of modern mandrel tooling.
