Ultra-High-Strength Steel
WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 2021 Porsche 718 Cayman, 2021 Porsche 718 Boxster, 2020 Porsche 718 Cayman, 2020 Porsche 718 Boxster, and 2019 Porsche 718 Cayman. However, it is still accessible from the selected car via links, so may be relevant.
Information
- Only "Genuine Porsche spare parts" must be used for repair work.
Information
Ultra-high-strength steel panels are extremely strong and rigid. These body parts are recast warm during manufacturing and are press-hardened in cooled recast tools.
Damaged or deformed body parts can impair torsional rigidity, flexional resistance and crash safety.
Information on ultra-high-strength steel:
- Ultra-high-strength body parts must only be replaced as a complete unit.
- Ultra-high-strength body parts can no longer be reshaped.
- Straightening and reshaping is not permitted.
- Use special drill bits for drilling ultra-high-strength steel.
- Resistance spot-welding can only be carried out using the inverter welders currently approved by Porsche AG.
- Plug spot-welding ultra-high-strength steel does not produce sufficiently strong joints. If holes need to be welded, additional welding seams must be applied.
- For butt, overlap and reinforcement welding, the individual spot welds and welded seams must be at least 30 mm long.
- Resistance spotwelds can also be replaced by blind rivets and adhesive. The number of rivets must be increased for ultra-high-strength steel panels.
If repairs are needed, always read the specific instructions in the relevant Workshop Service Information.
