Featuring minimum tensile strength levels of between 1,000 and 1,400 MPa, a series of new cold-rolled ultra-high-strength steels combine superior performance with low weight. Named Docol UHS, the new steels are particularly applicable to the automotive industry. Their high energy-absorbing properties, for example, make them useful as structural members and for components used in a car's crumple zone. Jan-Olof Sperle, research manager for SSAB Swedish Steel, points out that "the steel is hardened before leaving the factory. Consequently, industries using these steels no longer require their own warm-up plants and hardening furnaces." Cutting, shaping, and welding, he adds, are achieved with traditional methods. The Docol UHS series consists of three standard steels: Docol 1000 DP, Docol 1200 DP, and Docol 1400 DP. Numbers relate to maximum loads measured in megapascals, MPa.

Fifty-six-year-old Pasquale Russo has been doing metalwork for more than 30 years in a tiny southern Italy village. Many craftsmen like him brought with them fabrication skills when they came from the Old World to America.
Linear guides are one of the most important components required for the design of automated or computer-controlled equipment. Aluminum profile extrusions, used for these guides, can enable designed-in functional features.
