We have released Tokidoki Communication VOL.23! 【Hotta Hagane Co., Ltd.】

High-quality steel (SCM435H-H, SCM440H-H) that has been heat-treated while in a black skin condition. An eco-file is currently being offered for easy inventory confirmation at a glance.

The SCM steel (round bar) that has been quenched and tempered, 'SCM435H-H' and 'SCM440H-H', is material that has been treated in a tempered state while still in its black skin condition. For example, 'SCM440H-H' is available in a wide range of sizes from φ16 to φ150. Additionally, we have established a supply system that allows for quick responses, and we can also flexibly accommodate material cutting and component processing. 【Features】 ■ Material treated in a tempered state while still in black skin condition (products that have undergone marquenching) ■ Issuance of heat treatment certificates is possible ■ Abundant inventory and efficient delivery system ★ We are currently offering a set of two types of "Eco Files (paper)" that allow you to check product specifications and inventory status, similar to a comprehensive catalog. If you are interested, please apply through the inquiry form.

Four products (SNB7-R, SNB7-H, SNB7-Pull, SNB16) that can be applied to various uses. An eco-file for easy specification confirmation is currently being offered.

We offer four types of high-temperature bolt steel that can be applied to various uses: 'SNB7-R', 'SNB7-H', 'SNB7-Pulled', and 'SNB16'. We maintain a rich inventory of sizes and can respond quickly to supply requests. We also accommodate material cutting and component processing. Additionally, we can provide compliance certification for component values according to ASTM standards. For some products, we can also provide heat treatment certification. 【Features】 ■SNB7-R: Alloy steel bolt material used for pressure vessels, valves, flanges, and fittings. ■SNB7-H: Quenched and tempered 'SNB7' in its black skin state. ■SNB7-Pulled: Quenched and tempered 'SNB7' in its black skin state, followed by pickling and pulling. ■SNB16: Vanadium is added to enhance heat resistance efficiency. ★ We are currently offering a set of two types of "Eco Files (paper)" that allow you to check product specifications and inventory status, similar to a comprehensive catalog. If you would like to receive them, please apply through the inquiry form.

• Other metal materials

Excellent corrosion resistance, heat resistance, and strong against rust! For kitchen utensils, nuclear facilities, and more.

This product is made from SUS304 that has undergone solution heat treatment and further peeling processing. Solution heat treatment is a process that dissolves alloy components into the material and rapidly cools it to prevent the formation of precipitates. This results in a material that is more resistant to rust. 【Features】 ■ Solution heat-treated product ■ Excellent corrosion resistance and heat resistance, strong against rust ■ Used in bolts, springs, kitchen utensils, nuclear facilities, etc. *For more details, please feel free to contact us by phone or through the inquiry form below.

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm. Please feel free to contact us for more information!

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out 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. ◎ If a detailed technical explanation is needed, please contact us.

● The production time for casting prototypes can be shortened! Since model production is not required, the time needed to create prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! With one molding process, different products with similar shapes or varying dimensions can be molded at the same time. This allows for the verification of multiple types in a short period.
