    • Hard steel - HIGH CARBON CONTENT .45%-.85%
    • Spring steel - high carbon content .85%-1.8%
  2. Steel Types
    • Stainless Steel - alloy contains P 12% chromium

    • Anodizing - process of thickening and tinting oxide film
    • Easily extruded
    • Need to isolate from other metals to prevent galanic action
  4. Glavanic Series
    • Least reactive - gold, platinum
    • Most reactive - aluminum, zinc, magnesium
  5. Nonferruous Metals - Copper/Brass
    • Copper - ductile, corrosion resistant due to oxide film
