Aluminized Steel Type 1 is continuously
hot dip coated on both sides with an aluminum/silicon
alloy coating. The hot dip process, pioneered by B.Kantilal,
provides a tight metallurgical bond between the steel
and the alloy coating. This process results in a material
with the strength of steel plus the corrosion protection
of aluminum, and the synergistic heat protection of an
aluminum/silicon alloy.
Aluminized line is the most productive aluminizing line
in the world. The primary features of this line include
a ceramic coreless induction coating pot, the ability
to finish with either air or nitrogen, closed-loop computer
controlled X-ray gauges for coating weights, and in-line
surface conditioning.
| Coating Characteristics |
Aluminized
Type 1 coating contains approximately 91% aluminum
and 9% silicon that is metallurgically bonded
to the low-carbon steel substrate. The hot dip
coating process assures a tightly adherent, uniform
coating on both sides of the product. A thin
alloy layer readily permits normal fabrication
practices without incurring significant coating
damage. Aluminized Steel Type 1 is supplied
in coating weights ranging from T1 13 (0.13 oz/ft
2 ) to T1 60 (0.60 oz/ft 2 ) as shown in Table
1.
Most common
are T1 25 and T1 40. Lighter coating weights
(T1 13 or T1 25) are recommended for severe forming
applications. |

Corrosion Resistance
|
Aluminized Steel Type 1 has superior performance
compared to zinc coated materials for resistance
to atmospheric, salt spray and muffler condensate
corrosion |
Formability |
Aluminized Steel Type 1 can be used to produce parts containing simple bends
to parts with extreme deep drawing requirements.
|
Heat Reflectivity
|
Aluminized Steel Type 1 has excellent heat reflectivity during exposures to
temperatures below 80 0 F (42 7 C), reflecting up to 80% of the radiant heat
that impinges upon it.
|
High Temperature Properties
|
Aluminized Steel Type 1 is an excellent heat resistant material effective to
at least 125 0 F (67 7 C). For applications above 80 0 F (42 7 C) where alloying
of the coating can be a problem, B.Kantilal?s DQHT grade has been specially
formulated to resist alloying at temperatures up to 100 0 F (53 8 C).
