• LS - Good repairability and weldability (least
sensitive to heat). May be attached using the
preferred Squeeze Type Resistance Spot Welding
(STRSW) process, weld bonding where appropriate,
or MIG welding. Materials have a tensile strength
of less than 270 MPa.
• HS - Some repairability and good weldability (the
higher the strength of the steel, the greater the
sensitivity to heat). May be attached using STRSW,
weld bonding, and MIG welding. Material tensile
strength range between 270 MPa and 600 MPa and
includes DP590.
• VHS - Very limited repairability and weldability (very
sensitive to heat). Attach only at OE defined
locations using OE defined procedures. Material
tensile strengths are greater than 600 MPa.
This category includes hot-stamped boron materials
which are also termed "press hardened."
Specialized cutters are required with many materials
in this group. May be attached using STRSW, weld bonding and Metal Active Gas (MAG) brazing to minimize
heat affected zone.
• LM - Good repairability but no weldability. May be attached by rivet bonding or urethane. Only install a
laminated steel component using urethane if the OE component was installed with urethane.
• AL - Stamped aluminum sheet metal panels may be repairable with specialized tools and techniques.
• MG - Magnesium - no repairability, replacement components only.
• PL and PL-R - Some repairability depending upon the type of plastic involved, the degree of damage, and the
component function. Cosmetic components such as fascias (PL) have a higher degree of repair allowed than
those components which can carry components and loads. Where PL-R components are bonded to steel
structure, FCA US LLC will identify the proper adhesive to attach the replacement panel. Repair materials for
PL are commonly available in the collision repair market.
• CO - Composite materials may be fiber reinforced (ex: Kevlar) panels or co-molded assemblies of steel and
plastic. Any of these require specialized repair materials and processes.
