	Carbon content, steel classifications, and alloy steels By: Bob Capudean, Contributing Writer Steel classification is important in understanding what types are used in certain applications and which are used for others. For example, most commercial steels are classified into one of three groups: plain carbon, low-alloy, and high-alloy. Steel classification systems are set up and updated frequently for this type of information. Publish date: August 28, 2003 Tech cell: Metals/Materials
	Knockout punch: Hand-in-glove fit between application and process has Sanmina-SCI punching out profits By: Scot Stevens, Contributing Writer The system Sanmina-SCI uses to produce rails for Sun Microsystems' large servers is a key factor in Sanmina-SCI's competitiveness when it comes to processing a large, heavy-gauge, complet part, delivered in large volume on an as-needed basis for computer server systems and other similar applications.

	Hot-stamping boron-alloyed steels for automotive parts: Array By: Array Array Publish date: Array Tech cell: Press Technology
	Steel thixoforming: Emerging technology may help steel parts compete with other materials By: Todd Helms The demand for lightweight, high-strength components is increasing at the expense of traditional steel parts.Emerging technologies, such as steel thixoforming, may help reverse this trend. Thixoformed steel parts are significantly lighter than equally strong parts formed by conventional means. Publish date: April 10, 2007 Tech cell: Press Technology
	Hydraulic presses for hot stamping meet weight, safety mandates: It's all in the dwell By: Rick Nicholson Hot stamping of automotive structural safety components developed in response to mandates levied by the U.S. National Highway Traffic Safety Administration (NHTSA) 1 to improve vehicle crash integrity while also reducing vehicle weight to help meet fuel efficiency standards. Heating a high-strength steel (HSS) component of a boron-steel alloy to the austenitic range—a super-heated solid solution state, ~ 1,700 degrees F (950 degrees C)—improved drawability, and then quickly cooling the part in a water-cooled die, or quenching, transformed the crystalline structure, increasing the formed component's strength-to-weight ratio.

	The pressure is on: Prolonging die life with the help of sensor film By: Mirco Graenert and Shawn Eeles The traditional method of measuring pressure distribution in stamping operations—the die spotting blue technique—reveals the pressure points without actual pressure readings, making it difficult to balance in relation to other die components. A thin, flexible, Mylar-based sensor film that instantly captures and permanently records pressure distribution and magnitude between any two mating or contacting surfaces has emerged as an alternative to traditional pressure testing.

	Hot-stamping boron-alloyed steels for automotive parts Part I: Part I: Process methods and uses By: Taylan Altan Hot-stamped parts are being used increasingly in cars in Europe and North America. Ultrahigh-strength steels, like boron alloys, which meet automotive safety and crash requirements, are difficut to form with cold stamping, so hot stamping with die quenching has been applied.

	Hot-stamping boron-alloyed steels for automotive parts Part II: Part II: Microstructure, material strength changes during hot stamping By: Professor Taylan Altan Compared with cold-formed parts, hot-stamped parts provide better formability at high temperatures and exhibit no springback on the final part.

	Hot-stamping boron-alloyed steels for automotive parts Part III: Part III: Tool design and process simulation By: Taylan Altan To accurately model the hot-stamping process, FE simulation needs to account for the mechanical, thermal, and microstructural changes in the workpiece.

	Opening the gate to efficiency: Farm equipment-maker combines new, custom machines to boost productivity By: Stephanie Vaughan, Contributing Writer Since 1945 family-owned and -operated Tarter Gate has grown in staff and sales as it has changed the design of its products. To keep up with sales, continue growing the company, and absorb as many rising costs as possible — particularly in steel and fuel prices — the company uses custom machines and new technologies to its advantage.

	Welding aluminum piping: Best practices, differences between aluminum and steel pipe welding By: Frank G. Armao Steel and aluminum have distinctly different properties, and this is important if you're manufacturing aluminum piping systems. Learn the differences in welding steel and aluminum pipe and how they apply to the best practices you can use to weld aluminum pipe effectively.

	Drive fast, weld right: Motorsports fabricators use more than tools to build topnotch race cars By: Stephanie Vaughan, Contributing Writer Of all the fabrication tools necessary to build -- and repair -- race cars, welding equipment is one of the most essential. To keep a race car together, safe for drivers, and at its competitive best, welding and metallurgy come into play every day in the motorsports industry.
