Philosophy

Great Cars Are Made with
Great Steel.
Aichi Steel, a member of the Toyota Group, started from the determination to make steel
for domestically produced popular car production from scratch. The origin lay in thewords of the founder Kiichiro Toyoda, who said that “Great cars are made with great
steel.” This high aspiration subsequently evolved into the mission of “A great society
comes from great materials.” This DNA of challenge and creativity has been steadily
carried on by Aichi Steel to this very day.

Our Vision

From our role as a materials manufacturer, Aichi Steel, a
specialty steel manufacturer belonging to the Toyota Group,
has achieved development to this day with the enormous
mission of supporting Japan’s automobile and many otherindustries from their roots. The development of specialty
steel is nothing less than the development of manufacturing
itself; it is a material of unlimited potential. Aichi Steelsupplies products around the whole world with prime
quality and delivery. We believe that it is their safety andreliability that support the world’s development. Cherishingthat desire, our aim is to be a world-leading materials
manufacturer that people hope will continue its presence intheir region forever.

A Great Society
Comes fromGreat Materials.

We will strive to make positive contributions
to society by providing appealing products
from global perspectives and based on our
vibrant and trustworthy corporate qualities.

Manufacturing that Contributes to the Global Environment
Aichi Steel is a resource-recycling company that uses steel scrap generated during dismantling of automobile bodies andinfrastructure and other processes as a raw material to perform manufacturing.
In addition, we have achieved the integration of forging with steel making processes, enabling us to perform unified development
and production of steel materials to forged products at the same site.
Taking advantage of these strengths, we create environmentally-friendly products that are stronger, lighter, and more functional.

Resource-Recycling Manufacturing
Steel Scrap
Steel scrap is the main raw material
used in the specialty steels
manufactured by Aichi Steel. There
are various types of steel scrap
including scrap generated during
automobile body processing and thatfrom end-of-life vehicles.

Automobiles
Our high-quality products, madewith high technology, support theadvancement of motorization andprovide safety and security.

Steel Making
Part Processing

Material Design
Technology

We provide optimal process anddesign technology solutions that
contribute to customer part
designs and solutions.

We perform chemical composition
design of steel materials withexceptional characteristics including
higher strength, lighter weight,
and enhanced functionality tomeet the needs of each customer.

We melt steel scrap in an electric
furnace, and after adding
ferroalloys to adjust the chemicalcomposition, we then manufacture
large pieces known as steel blooms
in continuous casting machines.

Technologies That Support the Integration of Forging with Steel Making Processes
Forging Process
Technology

Forged Products
We achieve the high quality,
strength, and durability demanded
for automotive parts by assembling
our forged products into e-Axle,
engine, and driveline and chassis
components.

Steel Processing
Technology

Technological development in the
integration of forging with steel
making processes achieves low
environmental impact and low
cost through the pursuit ofprocess omission and near net
shape manufacturing.

By optimally combining newtechnologies and expertise
relating to existing technologies,
we are able to reduce CO2
emissions and create steel
materials with higher quality atlower cost.

Forging
The steel material selectedaccording to the productspecifications is forged into thespecified automotive partshape. The internal strengthof the parts is dramaticallyincreased by applying pressure.

Electronic components that support
power semiconductors

Utilizing the strengths of our integrated forging
process design technology, in areas ranging
from steel products to forging and machining,
we will respond to the changing and diversifying
needs of our customers as mobility advances.

Our high-quality heat dissipation components
and lead frames created through proprietaryhigh-precision pressing processes and extremely
clean plating technology are used in manyelectric vehicle inverters. We are contributing
to the widespread adoption of safe and secure
electric vehicles.

Global Magnetic Positioning System(GMPS) that accurately measuresposition of autonomous vehicles

Contributing to the creation of a hydrogensociety with stainless steels forhigh-pressure hydrogen

We are contributing to safe autonomous drivingwith technology that enables highly accurate
estimation of vehicle position in all environments
including tunnels and underground, where GPS
cannot be accessed, and in snow, fog, andbacklighting, which make the use of opticaldevices difficult.

We developed and launched stainless steel
products for high-pressure hydrogen ahead ofother companies, contributing to the spread offuel-cell vehicles, fuel-cell trucks and buses,
fuel-cell ships, and hydrogen-refueling stations.

Stainless steels maintain high ductility
under cryogenic temperatures

Stainless steels enable super long service
life and maintenance-free operation

Unlike commonly-used steels, stainless steels
are highly ductile at extremely low temperatures.
Therefore, stainless steels are and in the future
will continue making solid contributions tobuilding energy infrastructure related to liquid
natural gas (LNG), liquid hydrogen, and so on.

Highly corrosion-resistant stainless steels are
and in the future will continue making further
contributions to developing and updating water
infrastructure including flood control, wateruse, water storage, water purification, watersupply, waste water treatment and desalination.

The Value We Provide to Society

Healthcare

Healthy Living with
Advanced Technologies
We use our proprietary technologies to deliver health and peace of mind to people aroundthe world so that they can enjoy healthy and comfortable living throughout their lives.

Expanding the possibilities of cutting-edge
healthcare with amorphous wire

High-sensitivity magnetic sensors candetect the weak magnetic pulse of the heart

By equipping medical devices intended for
insertion into the body with highly-functional
amorphous wires, ultra-fine metal fibers thatare thinner than a human hair, more accurate
positioning becomes possible, expanding thepossibilities of healthcare.

Extremely weak magnetic information generated
by the heart and other organs can be read by
high-sensitivity sensors without the need to uselarge equipment, contributing to the developmentof increasingly miniaturized medical devices.

Easy-to-use dental magnetic attachments
Compact magnets with strong attractive force
make it possible to easily insert and remove
dentures, facilitating use by the elderly andthose with limited hand mobility, thereby
contributing to the recovery of oral functions.

Agriculture

Using the Strength of Iron to Contribute toAgriculture in Japan and Around the World
Preserving the global environment is a crucial issue for the development of a sustainable society, and the role that companies
should play in this is being called into question. We use the strength of Iron to contribute to agriculture in Japan and overseas.

Iron fertilizers revitalize agricultural
products in Japan
Even when plants are weakened due to low- or
high-temperature stress or other factors,
easily-absorbed ferrous ions make it possible
to grow vigorous plants.

thereby reducing forging CO2 by 51%.

Reusing heat from iron melting

Toward the practical application ofhydrogen combustion

We introduced a system that recovers exhaust
heat from electric furnaces in the form ofsteam energy through exhaust heat recovery
boiler and effectively uses it for vacuum
degassing equipment and other equipment,
contributing to CO2 reduction.

In 2023, a burner that combines hydrogen andcity gas has been installed in a heat treatment
furnace at Kariya Plant. In the future, hydrogen
combustion for heat treatment of stainlesssteel will be put into practical use after thedevelopment of hydrogen combustion technology
and demonstration tests.
