TOYOTA CAMRY 2000 Service Repair Manual

High Strength Sheet Steel
HIGH±STRENGTH STEEL (HSS) PARTS
Generally, High±Strength Steel (HSS) is that which has an intensity value of at 35 kgf/mm2
(343 MPa), and
distinguished from mild steel.
The handling of HSS is the same as for mild steel, but the following should be observed.
1. Panel Hammering: Because HSS is thinner than mild steel, care should be taken to avoid warping
during hammering operations.
2. Removing Spot Welds: Because HSS is tougher than mild steel, damage will occur more easily to a
regular drill. Therefore, an HSS Spot Cutter is recommended.
Also, use a high±torque drill at low speed, and supply grinding oil to the drill during use.
3. Panel Welding: Panel welding procedures for HSS are exactly the same as for mild steel. Plug weld-
ing should be done with MIG (Metal Inert Gas) welder. Do not gas weld or braze panels at areas other
than specified.

RUST±RESISTANT SHEET STEEL PARTS
Rust±Resistant Sheet have zinc, tin or aluminum etc, plating over the base metal surface in order to improve
the corrosion resistance of the sheet metal. For the vehicle's body panels, galvannealed sheet steel is widely
used.
Body panel on TOYOTA models are made of two different galvannealed sheet steel. The ordinary galvan-
nealed sheet steel has a zinc±iron alloy plating over the base metal surface. Zinc±iron alloy double±layer
galvannealed sheet steel has zinc±iron alloy plating on both the outside and the back surface, plus a further
iron±rich zinc±iron alloy plating which has good paint adhesion. These two galvannealed sheet steels are
used selectively according to need.

Galvannealed Sheet Steel Excelite II
The handling of Rust±Resistant Sheet Steel is the same as for ordinary sheet steel, but the following
should be observed.
1. Panel welding: The paint as well as the zinc portion must be removed completely from the welding
area to guarantee good welding integrity.
2. Anti±Rust Treatment: Since the zinc plating is lost after welding, anti±rust treatment of the welded
area must be thoroughly performed (refer to section AR).
