REPAIRING HIGH STRENGTH STEEL

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, because it may weaken the compo-
nent. When heating is unavoidable, never 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 sections of the body. In this case, increase the number of
measuring points, and carefully pull the HSS panel.

• When cutting HSS panels, avoid gas (torch) cutting if possible.

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 (1.97 in).
