Chevrolet Trax: Dual phase steel
This information provides repair recommendations and general guidelines for
steel classified as Dual Phase
Steel (dual phase steel with a tensile strength up to and including 800 MPa),
also known as DP.
General Motors recommends the following when repairing or replacing this type
of steel during collision repair.
NOTE: The use of heat to repair damage is not recommended for this
classification of
steel.
Recommended Repairs
- Cold repairs can be performed on this type of steel, unless the damage
includes kinks. If the damage
includes kinks, the part should be replaced.
- Sectioning or partial replacement of this type of steel is recommended
only at approved locations, in a
specific sectioning procedure.
- This type of steel can be used as a sleeve, or backer plate, when
recommended in a specific sectioning
procedure.
- Squeeze resistance spot welding can be used to replace factory spot
welds, where applicable.
- MIG plug welding and MIG stitch welding can be used on this type of
steel.
- MIG brazing can be used on this type of steel.
HIGH STRENGTH LOW ALLOY STEEL
This information provides repair recommendations and general guidelines for
steel classified as High Strength
Low Alloy Steel, also known as HSLA. This type of steel normally has a tensile
strength range from 300-700
MPa.
General Motors recommends the following when repairing or replacing this type of
steel during collision repair.
Recommended Repairs
- Cold repairs can be performed on this type of steel, unless the damage
includes kinks. If the damage
includes kinks, the part should be replaced.
- Controlled use of heat can be used to repair damage, if the heat does
not exceed 650º C (1200º F). The
heat should be applied a maximum of 2 times, for up to 90 seconds.
- Sectioning or partial replacement of this type of steel is recommended
only at approved locations, in a
specific sectioning procedure.
- This type of steel can be used as a sleeve, or backer plate, during
sectioning procedures.
- Squeeze resistance spot welding can be used to replace factory spot
welds, where applicable.
- MIG plug welding and MIG stitch welding can be used on this type of
steel.
- MIG brazing can be used on this type of steel.
MILD STEEL
This information provides repair recommendations and general guidelines for
steel classified as Mild Steel. This
type of steel normally has a tensile strength less than 270 MPa. This includes
the common steel names of:
- Mild Steel
- Bake Hardenable Steel (BH)
- Solid Solution Strengthened Steel
General Motors recommends the following when repairing or replacing this type
of steel during collision repair.
