Lightweight Steel Sheets These sheets, used for the outer panels of automobiles, offer both high strength and good workability — properties which until now were difficult to combine in a single product. They can be thin due to their high strength, and their thinness saves weight. The new sheets resist denting by flying pebbles and are stiff enough to prevent noise and vibration when the vehicle is running. They are now available in several types: sheets for general forming, with good bend ability; low-yield ratio sheets with high strength and high ductility; sheets for deep drawing, with high Lankford value; and sheets of bake-hardening type for deep drawing, their strength rising when paint-baked. These products are offered in a range of tensile strength from 35 - 100 kg / mm2. Coated and one-side coated high-strength steel sheets are also on the market.
