In the limited context of tube-bending tooling materials, a steel that is alloyed with moderate amounts of chromium and other elements such as molybdenum. Alloy steel is distinguished from stainless steel by having good hardening characteristics and is distinguished from tool steel by possessing better “toughness” after hardening.

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.
