REPAIRING HIGH STRENGTH STEEL

REPAIRING HIGH STRENGTH STEEL

High Strength Steel (HSS)

INFOID:0000000001672401

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:

SP130 is the most commonly used HSS.

SP150 HSS is used only on parts that require much more strength.

Read the following precautions when repairing HSS:

1.

Additional points to consider
• The repair of reinforcements (such as side members) by heat-

ing is not recommended since it may weaken the component.
When heating is unavoidable, do not heat HSS parts above
550

°

C (1,022

°

F).

Verify heating temperature with a thermometer.
(Crayon-type and other similar type thermometer are appropri-
ate.)

• When straightening body panels, use caution in pulling any

HSS panel. Because HSS is very strong, pulling may cause
deformation in adjacent portions of the body. In this case,
increase the number of measuring points, and carefully pull
the HSS panel.
