501-25-18 Body Repairs - General Information 501-25-18 DESCRIPTION AND OPERATION Body Sheet Metal Types of steel Steel body panels are still the most important materials used in the fabrication of stressed skin vehicle bodies. In addition to the familiar types of steel, reinforced high-strength and also ultra-high-strength special steels are used in vehicle body construction. Types of steels are classified by their properties of strength and elasticity. 1 2 3 4 5 E116044 Pos. Used type of steel Application range (Examples) 1 Ultra High Strengh Impact Carriers, Steel (UHSS) Bumper Carriers, A- B-Pillar Reinforce- ments 2 Extra High Strengh Frame Side Steel (EHSS) Member; Rocker Reinforcements 3 Very High Strengh Wheel House; Steel (VHSS) Structural Members ‡ Normal strength steel has a minimum yield strength of up to about 210 N/mm×. ‡ High strength steels have a minimum yield strength of about 150 to 600 N/mm×. ‡ Ultra-high-strength steels have a minimum yield strength of about 400 to 1200 N/mm×. High-strength and ultra-high-strength steels are mostly installed in safety relevant locations (structural components). Among others, these are side members, pillars, roof frames. Pos. Used type of steel Application range (Examples) 4 High Strengh Steel Roof Sticks, (HSS) Fenders 5 Normal strength Outer Panel steels Normal strength steels Normal strength steels are most often used in body construction. They are relatively soft and are therefore particularly suitable for the deep drawing
