Maintenance-reducing weather-resistant steel material 'COR-TEN'

Maintenance-reducing weather-resistant steel material 'COR-TEN'

The repainting cycle is extended compared to when painted on ordinary steel! It suppresses rust progression.

"COR-TEN" is a weather-resistant steel that uniquely overcomes the greatest weakness of steel, which is rust, by preventing it with rust itself. When left exposed to the atmosphere in its bare form, it initially rusts like ordinary steel, but eventually, due to the action of alloying elements, it forms a dense rust layer (protective rust) on the surface, which suppresses further rust development. When this product is painted, the repainting cycle is extended compared to ordinary steel, thereby reducing repainting costs. It contributes to the reduction of LCC (Life Cycle Cost) and environmental impact in various applications. 【Features】 ■ Prevents rust, the greatest weakness of steel, with rust ■ Forms a dense rust layer (protective rust) on the surface due to the action of alloying elements ■ Reduces repainting costs ■ Widely used in bridges, building exteriors, and more ■ Contributes to the reduction of LCC and environmental impact *For more details, please refer to the PDF document or feel free to contact us.

About the weather resistance of weathering steel "COR-TEN".

About the weather resistance of weathering steel "COR-TEN".

To generate protective rust, it is necessary to undergo cycles of wet and dry conditions in the atmosphere.

When exposed to the atmosphere, COR-TEN initially develops rust similar to ordinary steel, but over time, some of that rust gradually becomes dense and adheres closely to the base material. This rust layer protects the base material, thereby suppressing subsequent corrosion. This product was developed in 1933 based on the results of long-term exposure tests of over 30,000 specimens, and since then, global exposure tests and follow-up surveys of existing structures have continued, leading to improvements. The steel must contain weather-resistant elements that contribute to the formation of protective rust, and for weather-resistant steel to generate protective rust, it is necessary to undergo cycles of wet and dry conditions in the atmosphere. 【Features】 - The rust layer protects the base material, thus suppressing subsequent corrosion. - The steel must contain weather-resistant elements that contribute to the formation of protective rust. - Excellent weather resistance can be achieved by finding an optimal composition. - For weather-resistant steel to generate protective rust, it is necessary to undergo cycles of wet and dry conditions in the atmosphere. *For more details, please refer to the PDF document or feel free to contact us.

Can special steel be bent?

Can special steel be bent?

Depending on the characteristics of the steel materials, processing is done while adjusting the conditions! We introduce processing examples by steel type. *Can special steel be bent? Trivia materials are now available!

We would like to introduce our stock items regarding "bending processing of special steel." For the high-strength steel WEL-TEN590RE, which is suitable for press bending, and S-TEN1, which is suitable for roll bending, both are materials with good ductility and are suitable for bending processing. On the other hand, ABREX400 (wear-resistant steel plate) is a hard material, making it difficult to bend, and it has a strong springback (the force that causes the plate to try to return to its original shape), requiring technical expertise. However, there are some processes possible, such as gentle bends with a larger radius. Our company can accommodate inquiries regarding the feasibility of various bending processes, estimates, and processing. Please feel free to contact us. *For more details, please refer to the PDF document or feel free to reach out to us.*

Regarding the workability of weather-resistant steel "COR-TEN".

Regarding the workability of weather-resistant steel "COR-TEN".

We will introduce various processing capabilities such as cold bending, drilling, and cutting!

"COR-TEN" is a weather-resistant steel that protects against the weakness of steel, which is "rust," with "rust" itself, and has various workability features. It is possible to perform strain relief through spot heating and line heating. Just like ordinary steel, heating and strain relief do not lead to material degradation. Additionally, both shear cutting and gas cutting can be easily performed, just like with ordinary steel, and if preheating and post-heating are done before and after gas cutting, subsequent cold processing will be even better. [Workability Overview] ■ Cold bending processing ■ Drilling and cutting processing ■ Hot processing ■ Cutting ■ Strain relief through spot heating and line heating *For more details, please refer to the PDF materials or feel free to contact us.
