The metals/materials technology area has information on the most commonly used materials in metal fabrication ̶ carbon steels; stainless steels; high-strength, low-alloy steels (HSLAs); and the 6000 series aluminum ̶ and those that aren't as common, such as the red metals, refractory metals, titanium, and magnesium.

Zinc, which has been used to hot-dip-galvanize steel for 250 years, provides 50 to 75 years of corrosion protection in many environments. Empirical data collected about hot-dip galvanized (HDG) steel field performance from 1940 to 1980—in environments ranging from industrial to marine to suburban—indicates that zinc can prevent base steel corrosion more than other surface treatments. Because of zinc's long-lasting protection, projects require no maintenance and therefore no maintenance costs.

Dear Elmer:Is there a way to weld 1018 cold-rolled steel to cast iron? If so, how?JamesOwings Mills, Md.Dear James:You can weld 1018 low-carbon steel to cast iron using shielded metal arc welding (SMAW) and a nickel-based ENiFe electrode.Clean the surfaces before you start. If the joint is highly...

Talk about a can of worms ... From crystalline structures to phase diagrams and interstitial solutions, from microstructures to allotropic transformations, it sometimes seems that for every question metallurgy can answer, for every problem it can solve, it creates two more.

Production or fabrication processes can include dozens of stages to convert raw materials into finished goods. Regardless of the raw material or the finished product, one factor is constant - - most metals look alike.

Knowing how chemicals tend to react with one another and how each type of lubricant and coolant commonly used during steel processing tends to behave is a boon when you're trying to fabricate products properly.
