Achieving strength without heat treatment: high-strength, high-corrosion-resistant stainless steel bolts.

Achieving strength without heat treatment: high-strength, high-corrosion-resistant stainless steel bolts.

Non-magnetic, high-strength, and highly corrosion-resistant austenitic stainless steel bolts. They are environmentally friendly products that do not require heat treatment.

The "high-strength, high-corrosion-resistant stainless steel bolt" is made from austenitic stainless steel based on SUS304 and exceeds the strength classification A2 standard values of JIS B 1054. Through a proprietary molding process (patent obtained), it has achieved strength without the need for heat treatment. 【Features】 - Uses high-corrosion-resistant austenitic stainless steels SUS304 and SUS316 - Achieves high strength by utilizing material strength and work hardening through forging - The proprietary Bausinger effect suppression processing method eliminates the need for strengthening heat treatment, reducing environmental impact - Maintains high corrosion resistance and shortens lead time due to the absence of heat treatment processes - The screw head shape adopts a hexalobular design that offers high torque transmission - Balances corrosion resistance and strength, with a proven track record for use in automotive components (Note) The Bausinger effect refers to the phenomenon where, after applying plastic deformation in one direction, applying a load in the opposite direction results in plastic deformation occurring at a lower stress than when a load is applied again in the same direction. If you are interested in fastening with stainless steel components, please feel free to contact us.

Why doesn't it rust?! Basic knowledge of stainless steel: types and characteristics.

Why doesn't it rust?! Basic knowledge of stainless steel: types and characteristics.

This document explains why stainless steel does not rust and why it can rust. It is a technical document that outlines the types and characteristics of stainless steel.

Stainless steel is a highly corrosion-resistant alloy made by adding elements such as chromium and nickel to a base of iron to enhance its corrosion resistance. Due to its properties such as corrosion resistance, heat resistance, workability, and ease of maintenance, it is widely used in everyday items as well as large structures, with various applications ranging from household goods and transportation equipment to nuclear power and space development. Different types of stainless steel have been developed and manufactured to suit these applications. This document provides a clear explanation of the types and characteristics of stainless steel, the reasons for its rust resistance, and the conditions under which it rusts, offering fundamental knowledge about stainless steel. *For more details, please download the document or contact us directly.*

Non-treated, medium-strength bolts / Daiichi Kogyo Co., Ltd.

Non-treated, medium-strength bolts / Daiichi Kogyo Co., Ltd.

A manufacturing method that ensures strength without heat treatment through an independent forming process, taking environmental impact into consideration.

Plastic deformation is applied to metals, and as the degree of deformation increases, work hardening is achieved, resulting in a higher yield point than the original metal. The metal exhibits strong resistance to loads in the direction of the work hardening, but the yield point against loads in the opposite direction decreases, making it easier to undergo plastic deformation at lower stress levels. This phenomenon is called the Bauschinger effect. Our company has developed and launched a molding process technology that suppresses the Bauschinger effect. This special molding process enables the production of bolts with mechanical properties without the need for heat treatment. Non-quenched, medium-strength bolts are products that secure a strength classification equivalent to 8.8 without heat treatment. The absence of heat treatment reduces environmental impact and shortens manufacturing lead times. From development to evaluation, our team of experts is here to assist with the optimal design of screws. Please feel free to reach out to us.

Technical Data: High Strength and High Corrosion-Resistant Stainless Steel Bolts

Technical Data: High Strength and High Corrosion-Resistant Stainless Steel Bolts

We provide various technical information, including test results and material properties, about "high-strength, high-corrosion-resistant stainless steel bolts" that excel in strength and corrosion resistance.

The "high-strength, high-corrosion-resistant stainless steel bolt" is made from austenitic stainless steel materials SUS304 and SUS316, which excel in corrosion resistance. By utilizing forging processes to enhance material strength and work hardening, it surpasses the JISB1054 A2 standard values. 【Verification Experiment】 Stainless Steel Bolt Tensile Test (Size: M8 P1.25) ○ Tensile Strength: 1018.3 MPa ○ 0.2% Yield Strength: 854.6 MPa By introducing our self-developed Bauschinger effect suppression processing method into the manufacturing process, we have made it possible to secure strength without heat treatment. ○ It allows for strong processing without enhanced heat treatment, reducing environmental impact. ○ By eliminating the heat treatment process, lead time can be shortened. (※) The Bauschinger effect refers to the phenomenon where, after applying plastic deformation in one direction, applying a load in the opposite direction results in plastic deformation occurring at a lower stress than when a load is applied again in the same direction. This stainless steel bolt achieves both corrosion resistance and strength while also contributing to cost reduction. Detailed technical information is available in the technical report. Please download it to learn more.

Insert bolt that can be tightened without breaking the resin of "SSOO Bolt".

Insert bolt that can be tightened without breaking the resin of "SSOO Bolt".

A high-torque compatible embedded bolt for resin that is strong against rotation and withdrawal, and does not damage the resin. It allows for nut tightening when embedded in resin parts.

The "SSOO Bolt" is a resin embedded bolt (insert bolt) with a special octagonal head shape, offering excellent torque resistance and pull-out strength. An insert bolt is a bolt that is embedded in resin and fastened with a nut. By tightening with a nut, it allows for the fastening of resin parts to each other or resin parts to metal. It minimizes deformation and cam-out of the resin when fastened with high torque, enabling nut tightening at high torque levels. It can also be used for back embedding (thermal press fitting), making it suitable for shapes that cannot be integrally molded. Since the bolt can be used in an upright position within the resin, it improves the assembly of parts. The product design has been completely revamped, and sizes from M4 to M8 are now available. 【Features】 ● Special shape that minimizes cam-out and slip even when tightened with high torque ● Strong against pull-out, preventing deformation of resin parts ● Usable for both insert (simultaneous molding) and outsert (thermal press fitting) ● Mass production possible due to unique manufacturing methods ● Trusted Octa Lobular series *For more details, please refer to the materials. Feel free to contact us with any inquiries.

High Torque Compatible Resin Embedded Bolt "SSOO Bolt"

High Torque Compatible Resin Embedded Bolt "SSOO Bolt"

From the development stage, the bolt shape has been redesigned for weight reduction!

The "SSOO Bolt" is a high-torque embedded bolt (insert bolt) designed for resin that minimizes deformation and rotation of the resin when tightened with high torque, and is also resistant to pull-out. This bolt is embedded in the resin component with its head, and is secured with a nut. Since the male thread of the bolt stands above the resin, it improves the assembly characteristics of the components. It has been successfully used in the junction boxes and busbars of the traction motor system "e-Axle." Please feel free to contact us if you would like a sample. 【Features】 ■ Minimizes deformation and rotation of the resin when tightened with high torque, and is resistant to pull-out ■ Improved assembly characteristics due to the standing threads of the bolt ■ The special octagonal shape of the head and the serrated grooves on the outer circumference allow the resin to easily engage when embedded ■ Can be embedded either through simultaneous molding or post-insertion via thermal press fitting ■ The shape of the bolt head has been modified for weight reduction *For more details, please refer to the PDF document or feel free to contact us. *Thread sizes range from M4 to M8. Please consult us regarding the length.
