It is something that cannot be imitated by other ironware.
Thin, lightweight and easy to use
Iwate Steel has introduced a cutting-edge system called MAGMA5.
We carry out all of our own in-house design and improvement of casting methods (industrial castings), defect prevention (industrial castings), and development of thin-walled castings.
Because advanced systems are very expensive, this process is often outsourced to specialized companies or facilities, but Iwate Steel has created an environment where the process can be carried out consistently in-house, which has enabled it to quickly incorporate customer needs and employee ideas.
In product development for ironware and castings, it is necessary to collect data over time by repeatedly carrying out measures using actual casting.
However, by using a system that can simulate and predict prototype results in advance, it is possible to significantly reduce the time required to repeat the actual casting process. This allows time to be spent on trial and error in pursuit of ideas and functionality. The result is the birth of ultra-thin walled ironware products.
Castings and ironware also evolve with the times and technology. In the future, Iwate Steel will continue to evolve by developing even thinner ironware and realizing more efficient production processes, so that we can provide products that enrich the lives of our customers.

Iwate Steel turned its attention to ductile iron in order to achieve a thinner, lighter, and stronger cast iron than conventional ironwork. Ductile iron, also known as spheroidal graphite cast iron, is attractive because it has a strong structure in which the graphite is separated and the iron is connected to itself, whereas in ordinary cast iron, the graphite is connected to itself. However, while it is strong, it was considered very difficult to make it thin (thinning).
Iwate Steel has overcome this challenge after more than three years and more than 1,000 trials and errors, backed by its own high level of technical expertise. The company's proprietary "ductile thinning technology" overturns the conventional wisdom of cast iron products, achieving a "thinness" and "lightness" that is about half that of conventional cast iron products, while also retaining "strength," resulting in the creation of the "ductile series," an ironware that can be used for a longer period of time.
The fact that Iwate Steel can produce thin, high-quality ironware while maintaining a spheroidization rate of over 80% is the culmination of the high technical capabilities, or what could be called the craftsmanship, that it has cultivated over many years.

In order to achieve a thinner , lighter , and stronger cast iron than conventional ironwork, Iwate Steel turned its attention to ductile iron.
The appeal of "ductile iron," also known as spheroidal graphite cast iron, is that, unlike ordinary castings, where the graphite is connected to each other, the graphite is separated and the iron is connected to each other, making it a strong structure .
However, although it is strong, it was thought to be extremely difficult to make it thin (thin-walled).
Iwate Steel, backed by its own advanced technological capabilities, overcame this difficult problem after more than three years and more than 1,000 rounds of trial and error .
Using our proprietary "ductile thinning technology," we have overturned the conventional wisdom of conventional cast iron products, achieving a thickness and lightness that is roughly half that of conventional products, while at the same time maintaining strength, resulting in the creation of the "Ductile Series," a type of ironware that can be used for a longer period of time.
The fact that Iwate Steel can produce thin, high-quality ironware while maintaining a spheroidization rate of over 80% is the culmination of the high technical capabilities, or what could be called the craftsmanship, that it has cultivated over many years.

Revolutionizing cast ironware.
"Rust-free ironware" makes it even easier to use.
The main causes of rust are oxidation and scratches.
Iwate Steel has overcome these two challenges with its unique surface modification, a world first for cast ironware.
Iwate Steel's unique surface modification involves first applying a nitrogen treatment to the base metal of the casting, which makes the surface of the casting hard and strong, so that it will not get scratched even if it is scrubbed with a scrubbing brush .
After the "nitrogen treatment", the ironware is further subjected to "oxidation treatment" (a process in which the iron is intentionally oxidized to a black color = rusting) to make the ironware itself no longer susceptible to rust .
Furthermore, while typical ironware is painted with an anti-rust coating to prevent rust, Iwate Steel's unique technology that combines nitrogen processing and oxidation processing allows it to create rust-free ironware without the use of anti-rust coatings .
As a result, the anti-rust coating on ordinary ironware will wear off over time, and it is necessary to maintain it by applying oil after use, but Iwate Steel's "Ductile Series" requires no maintenance.
It is easy to care for - just wash and dry - and you can use it for a longer period of time with greater comfort.

"Iwate Steel's unique surface modification + surface irregularities"
Prevents burning.
Completely different from surface treatments such as Teflon coating or enamel, this method diffuses nitrogen and oxygen onto the surface of the iron.
The surface of the casting base has been modified to prevent rust as well as peeling and leaching.

Iwate Steel's "Ductile Series" does not use Teflon® or fluororesin coatings to prevent sticking . It can also be used on induction cooktops without any problems .
(*Because polishing marks may remain, we apply a baked-on paint in accordance with the Food Sanitation Act to ensure a nice appearance.)
However, the reason it doesn't burn is because
This is the result of Iwate Steel's unique surface modification .
Nitrogen processing makes the casting surface hard and strong.
Fine irregularities of about 2 to 3 μm are formed on the surface .
This reduces the contact area of the food with the ironware surface and also allows the food to blend better with the oil, so even a small amount of oil is distributed evenly over the entire surface, greatly reducing burning.
Even if it does burn, you can easily scrub it off with a scrubbing brush.
You can use it for a long time without worrying about the Teflon or fluororesin coating peeling off and getting into your body.
