Ultra High Strength Steel Part

INFOID:0000000010505349

DESCRIPTION

Ultra high strength steel parts signify high strength steel plates with tensile strength of 980 MPa or more.
When replacing parts made of ultra high strength steel or parts including ultra high strength steel, never per-
form the prohibition described below:

PROHIBITION

WARNING:

Never cut ultra high strength steel parts or perform butt welding. Violation of this prohibition causes
extreme strength degradation, and the strength before damage cannot be secured.

PART REPLACEMENT

To replace an ultra high strength part, be sure to replace it by panel supply unit of ultra high strength steel part.
For the welding method, refer to 

BRM-341, "Welding of Ultra High Strength Steel"

CORROSION PROTECTION

Description

INFOID:0000000010499113

To provide improved corrosion prevention, the following anti-corrosive measures have been implemented in
NISSAN production plants. When repairing or replacing body panels, it is necessary to use the same anti-cor-
rosive measures.

Anti-Corrosive Precoated Steel (Galvannealed Steel)

To improve repairability and corrosion resistance, a new type of anti-
corrosive precoated steel sheet is adopted replacing conventional
zinc-coated steel sheet.
Galvannealed steel is electroplated and heated to form Zinc-iron
alloy, which provides excellent and long term corrosion resistance
with cationic electrodeposition primer.

NISSAN genuine parts are fabricated from galvannealed steel. Therefore, it is recommended that NISSAN
genuine parts or an equivalent be used for panel replacement to maintain the anti-corrosive performance built
into the vehicle at the factory.

Phosphate Coating Treatment and Cationic Electrodeposition Primer

A phosphate coating treatment and a cationic electrodeposition
primer, which provide excellent corrosion protection, are applied to
all body components.

CAUTION:

Confine paint removal during welding operation to an absolute
minimum.

NISSAN genuine parts are also treated in the same manner. Therefore, it is recommended that NISSAN gen-
uine parts or an equivalent be used for panel replacement to maintain anti-corrosive performance built into the
vehicle at the factory.

Anti-corrosive Wax

INFOID:0000000010499114

To improve corrosion resistance, anti-corrosive wax is applied inside the body sill and inside other closed sec-
tions. Accordingly, when replacing these parts, be sure to apply anti-corrosive wax to the appropriate areas of
the new parts. Select an excellent anti-corrosive wax which will penetrate after application and has a long shelf
life.

Undercoating

INFOID:0000000010499115

The underside of the floor and wheelhouse are undercoated to prevent rust, vibration, noise and stone chip-
ping. Therefore, when such a panel is replaced or repaired, apply undercoating to that part. Use an undercoat-
ing which is rust resistant, soundproof, vibration-proof, shock-resistant, adhesive, and durable.

Precautions in Undercoating

1.

Never apply undercoating to any place unless specified (such as the areas above the muffler and three
way catalyst that are subjected to heat).

2.

Never undercoat the exhaust pipe or other parts that become hot.

3.

Never undercoat rotating parts.

4.

Apply bitumen wax after applying undercoating.

5.

After putting seal on the vehicle, put undercoating on it.

Stone Guard Coat

INFOID:0000000010499738

To prevent damage caused by stones, the lower outer body panel (fender, door, etc.) have an additional layer
of Stone Guard Coating over the ED primer coating. When replacing or repairing these panels, apply Stone
Guard coating to the same portions as before. Use a coating which is rust preventive, durable, shock-resistant
and has a long shelf life.

Body Sealing

INFOID:0000000010499117

The following figure shows the areas that are sealed at the factory. Sealant that is applied to these areas
should be smooth and free from cuts or gaps. Care should be taken not to apply an excess amount of sealant
and not to allow other unaffected parts to come into contact with the sealant.
