[Explanation Material] Registered: Causes and Countermeasures for Stainless Steel Containers Rusting Quickly Under Certain Conditions.

Stainless steel is a metal that is "difficult" to rust!

We sometimes receive inquiries from customers saying, "Even though it's made of stainless steel, it rusted quickly." Stainless steel, as the English words "Stain (rust, corrosion) + less (less) + steel (steel)" suggest, is an alloy of iron that is highly resistant to rust. While it is much less prone to rust compared to regular iron, it is not completely rust-proof. This PDF document summarizes "Why is stainless steel resistant to rust?", "What causes rust on rust-resistant stainless steel?", and "What are the rust prevention measures for stainless steel containers?" You can view it immediately by downloading the PDF.

I have summarized the important cleaning methods to make stainless steel containers last longer.

After using a stainless steel container, it is essential to clean the container. However, incorrect cleaning methods can cause scratches or lead to rust. Here, we will introduce important cleaning methods to help prolong the life of stainless steel containers.

BA material, 2B material, buff polishing, electrolytic polishing... A grand reveal of stainless steel surfaces that cannot be discerned by the naked eye!

Smooth, rough, silky... Depending on the material and surface finish, stainless steel shows various appearances. However, it is not possible to see what the actual surface looks like just by visual inspection. Therefore, this time, we will introduce photographs of stainless steel surfaces taken using a scanning electron microscope (SEM). *What is a scanning electron microscope (SEM)?* Unlike optical microscopes (such as magnifying glasses and general microscopes) that use light, a scanning electron microscope uses electron beams. It allows us to clearly see fine surface structures that cannot be observed with optical microscopes.

Perfect for food factories! A simple structure dustpan made of all stainless steel.

A dustpan made of all stainless steel that is resistant to rust and hygienic. It has a small contact area, allowing it to be used without wobbling even on uneven floors. - Ideal for cleaning hygienic places such as food factories and areas around water. - Dustpans can be stacked on top of each other for space-saving storage. - The 【DPS-W】 model has a drainage hole in the tray, allowing you to stand while draining excess water and collecting only the trash.

This is an all-stainless steel cart used in a wide range of fields, including pharmaceuticals, physics and chemistry, food manufacturing, and kitchens.

○ This cart is made of stainless steel (SUS304), making it resistant to rust and easy to handle. ○ The handle is fixed by welding, ensuring stability without wobbling. ○ To ensure safe use, the corners of the cargo area are rounded. ○ It uses reinforcement materials on the back that do not accumulate dirt, making it sturdy and hygienic. ○ The 【NW-D-FB】 model comes with a foot-operated brake. Simply stepping on the pedal easily locks the wheels.

The Hyper CLT flooring is not only used on-site but also aims for further performance improvements through industry-academia collaboration with universities. To utilize wood in outdoor civil engineering sites, it is important to verify various challenges such as durability and water resistance. Therefore, Kaitaku Co., Ltd. continues research and development in collaboration with various universities. The goal is to connect research results to actual product improvements and new applications, evolving into more user-friendly and high-value wooden flooring. The Hyper CLT flooring is registered with the Ministry of Land, Infrastructure, Transport and Tourism under the NETIS technology "TH-250021-A." In addition to this NETIS registration achievement, research and development through industry-academia collaboration is ongoing. By combining the technologies of wood, NETIS, civil engineering, and universities, the Hyper CLT flooring further expands the possibilities of new civil engineering CLT.

In public works, not only construction quality but also safety measures, environmental considerations, and unique site-specific innovations are important. One proposal that is easy to suggest is the civil engineering CLT "Hyper CLT Mats" utilizing wood. These can be used for temporary roads, access routes, worker pathways, and material yards, improving the site environment from a different perspective than steel plates. It is also characterized by the ease of explaining the purpose of implementation to clients, such as measures against summer heat reflection, noise reduction, CO2 fixation, and consideration for the landscape. Furthermore, being a **NETIS registered technology "TH-250021-A"** by the Ministry of Land, Infrastructure, Transport and Tourism is a significant point when proposing in public works. It can be considered as one of the new technology applications and creative innovations. Clearly communicating "why this material is used" is also important when making proposals to government offices. The Hyper CLT Mats, which combine wood, NETIS, and civil engineering, are expanding their use in public works as a new civil engineering material that balances practicality and environmental consideration.

Metal cracks are one of the concerns in equipment maintenance operations. Conventional welding methods for repairs often change the base material around the crack due to heat, leading to residual stress and deformation, which constantly carries the risk of "crack recurrence" and "secondary damage." Hinode Waterworks Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for the repair of metal cracks without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material at all. Repairs can be made even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. For more details, please contact us or download the catalog.
