High strength steel (HSS)
High strength steel is used for body panels in order to reduce vehicle weight.
Accordingly, precautions in repairing automotive bodies made of high strength steel are described below:
Tensile strength | Nissan/Infiniti designation | Major applicable parts |
373 N/mm2 (38kg/mm2,54klb/sq in) | SP130 |
|
SP130 is the most commonly used HSS.
Read the following precautions when repairing HSS:
When heating is unavoidable, do not heat HSS parts above 550В°C (1,022В°F).
Verify heating temperature with a thermometer.
(Crayon-type and other similar type thermometer are appropriate.)
Instead, use a saw to avoid weakening surrounding areas due to heat. If gas (torch) cutting is unavoidable, allow a minimum margin of 50 mm (1.97in).
If spot welding is impossible, use M.I.G. welding. Do not use gas (torch) welding because it is inferior in welding strength.
Therefore, when cutting spot welds on a HSS panel, use a low speed high torque drill (1,000 to 1,200 rpm) to increase drill bit durability and facilitate the operation.
This work should be performed under standard working conditions.
Always note the following when spot welding HSS:
Handling of ultra high strength steel plate parts
PROHIBITION OF CUT AND CONNECTION
Do not cut and join the lower lock pillar reinforcement (center pillar reinforcement inside frame parts) because its material is high strength steel plate (ultra high strength steel plate).
The center pillar reinforcement must be replaced if this part is damaged.

Waxing
Regular waxing protects the paint surface and
helps retain new vehicle appearance. Polishing is
recommended to remove built-up wax residue
and to avoid a weathered appearance before
re-applying wax.
