  • Galvanizing - Grey Coatings on Hot-Dipped Steel
    Article - 26 Feb 2002
    Regardless of customer anticipations, hot-dip galvanized structural steel has a grey coating, rather than a shiny coating. This usually leads to disagreements between galvanizers and their customers.
  • Galvanizing - The Effects of Coating Thickness
    Article - 26 Feb 2002
    There are many types of coatings that are referred to as hot-dip galvanized. The hot-dip galvanization process necessitates the immersion of steel in molten zinc, which reacts with the steel to create...
  • Galvanizing Threaded Steels
    Article - 26 Feb 2002
    Threaded fasteners are galvanized in specialized galvanizing facilities that centrifuge the fasteners to remove excess zinc from the threads.
  • Galvanized Steel with a Powder-Coated Surface
    Article - 26 Feb 2002
    Steel products can be given a high-grade architectural finish by using a polyester powder coating over hot-dip galvanized steel. This coating is considered as one of the most long-lasting protective...
  • Galvanized Steel - Preparing Structural Steel for Painting
    Article - 26 Feb 2002
    There are many instances where hot-dip galvanized coatings will have to be painted. Well-established quality assurance processes are available for painting hot-dip galvanized parts, it is a usual...
  • Galvanized Steel - Underground Corrosion
    Article - 26 Feb 2002
    Buried steel products are open to a wide variety of corrosive forces that are rather different from those endured in the atmosphere. The durability of both steel and galvanized steel in in-ground...
  • Tungsten Applications - Lamps
    Article - 16 Feb 2002
    Compared to osmium, tungsten can endure significantly higher temperatures and has a very low vapor pressure. This results in more luminosity and an extended lifetime.
  • Tungsten Applications - Electrical Applications
    Article - 16 Feb 2002
    The only material that is practically used for electron emitters is tungsten. Although there are other electropositive metals that yield higher emission rates, tungsten has an extremely low vapor...
  • Special Applications with Tungsten
    Article - 15 Feb 2002
    Cobalt-chromium-tungsten alloys often referred to as stellite, are a group of wear-resistant alloys with applications where a tough wear-resistant material is necessary.
  • Using Tungsten in Bullets
    Article - 15 Feb 2002
    Every year, 200 million tungsten bullets are produced, each using an ounce of tungsten. That amounts to over 5500 tons or one-eighth of the current annual tungsten consumption across the globe.
