Forged Steel Products
QWhat are forged steel products?
Generally, raw materials that have been heated to a high temperature are hot-processed with a power press, air hammer, etc., and are called forged steel.
Forged steel products are those that have undergone further heat treatment to improve their mechanical properties and metal structure.
Through the forging process, it is possible to crush gaps inside the metal, refine the crystals and increase the strength, and at the same time, create the desired shape.
QWhat are competitive advantage of Seo’s forged products?
Integrated production - from procurement of raw materials, forging, and heat treatment to machining and mechanical testing is possible.
Our forged steel products with an integrated production system may not be high-class or expensive, but they do have a high degree of freedom, so they can be used effectively to reduce total costs and shorten delivery times.
Example:
○ Cast Product Forging
Improvement of internal quality, reduction of wood mold costs for small lots, reduction of welding repair man-hour
○ Sheet Winding Forging
Good for small lots, reduce welding man-hours, reduce weld inspection, improve quality by eliminating welding, shorten delivery time
○ Sheet Metal Forging
Reduction of welding man-hours, improvement of product strength, quality improvement, labor saving, etc.
In terms of quality, we can respond to high-pressure gas specific inspection equipment, various classification products, nuclear power, and CE mark products.

Heat Exchangers Products
QWhat is a heat exchanger?
This is a general term for equipment and devices that exchange heat.
It is used for efficiently transferring and exchanging thermal energy between two different fluids to heat and cool the fluids.
For example, if you heat a kettle to produce steam, the water inside will continually evaporate until you run out of hot water. Therefore, water must always be supplied. However, if you add water at room temperature, the water will cool down and will not evaporate. This is inconvenient, so heat the supplied water with the heat of the generated steam, and add it to the kettle. Auxiliary equipment that performs this heat exchange in order to achieve the objective efficiently is a heat exchanger.
QWhere are heat exchangers used?
They are primarily used in nuclear and thermal power plants, waste incineration plants, and renewable energy power plants.

QWhat is Seo Koatsu Kogyo?
electricity contributes to everyone's comfort behind the scenes.
Things that generate electricity are called generators. A thermal power plant produces steam with a boiler to operate a generator, and the steam turns a turbine that is linked to the generator. A heat exchanger is required as auxiliary equipment (accessory equipment) for boilers, turbines, and generators.
And a flange (forged steel) is required as a joint for piping between each device.
As a company with a history of more than 90 years, we are a pioneer of these forged products and heat exchangers.
Using forged steel products and heat exchangers as two pillars, we supply high quality and excellent products to each industry, and contribute to society with high technology.
QAre you currently accepting applications for hire?
Currently we are not.
