Overview and advantages of SUS631 raw material
SUS631 is a high-strength stainless steel raw material. Johoty uses its unique chemical composition and physical properties to design many high-precision connectors and springs. It is a precipitation hardening special stainless steel. It can achieve super-high strength and hardness through Johoty’s special heat treatment. Simultaneously maintaining a certain level of corrosion resistance and toughness. It can keep stable performance in high temperature of up to 315℃ and high pressure environments. Therefore, choosing SUS631 as the raw material for Pogo pin springs can effectively enhance their fatigue resistance. Reduce damage caused by raw material fatigue during long-term use.
Compared with traditional spring steel, SUS631 has significant advantages in elasticity and tensile strength. This raw material can withstand greater loads and can still recover its original state after multiple elastic deformations. Johoty also designs and produces high-end pogo pins based on repeated spring compression and release.

How can SUS631 raw material effectively prevent pogo pin spring fatigue?
The spring fatigue of pogo pin is caused by repeated mechanical stress. This stress will cause the spring to gradually lose its elasticity and ultimately fail to recover its original shape. SUS631 raw material can effectively slow down this process through its excellent fatigue resistance and strength.
Firstly, the high strength of SUS631 enables Pogo pin springs to maintain a low deformation rate after 200,000 uses. Secondly, the corrosion resistance of SUS631 greatly reduces material degradation caused by moisture, chemicals, and other factors. Therefore, the spring of Pogo pin can maintain stable power transmission performance even after repeated uses. Please refer to the table below:

Can SUS631 raw material improve the long-term stability of Pogo pins?
Stability is a key characteristic of Pogo pins in various applications, especially in high-demand electrical connections. The Pogo pin spring made of SUS631 material can maintain long-term stability under various extreme environmental conditions due to its excellent mechanical properties.
SUS631 can keep stable spring force and deformation recovery under high pressure and temperature. For Pogo pins commonly used in extreme working conditions, it is crucial. In electric vehicle charging stations and smart home devices, Pogo pins need to withstand frequent plugging and unplugging operations. Various high-end precision instruments require maintaining extremely low attenuation of pogo pins in terms of elasticity. SUS631 raw material ensures reliable connection even under high-frequency usage.
How to ensure stable power transmission of Pogo pins?
As an important connecting component in electronic devices, Pogo pins are required to provide stable power transmission. In high-frequency applications, the stability of power transmission has become the primary consideration for Johoty’s customers when using Pogo pins. The application of SUS631 raw materials has improved the fatigue resistance of springs. This ensures stable power transmission of the Pogo pin after prolonged operation. Customer verification shows that even after 200,000 uses, there is less than 1% elasticity attenuation.
SUS631 resistance of corrosion and high-temperature effectively reduce the impact of external environment on power transmission. Traditional raw materials are susceptible to moisture and chemical corrosion. Causing poor contact, thereby affecting the stable flow of current. SUS631 performs even better in these aspects. The power transmission of guest devices is more stable, and the connection quality is guaranteed.
SUS631 raw material extends the service life of Pogo pins
Pogo pins are used in many high-end manufacturing industries. Johoty’s customers usually require our pogo pins to be able to withstand long-term high load usage. Pogo pin springs made from SUS631 raw materials have long-term stability and fatigue resistance. The customer’s product is capable of continuously and reliably working for up to 200,000 lifetimes. The use of POGO pins made from SUS631 raw materials can greatly extend the overall service life of customer equipment.
The spring made of SUS631 raw material needs to be quenched and tempered to have high strength and high temperature resistance. In this way, Johoty’s Pogo pin can continue to work effectively in harsh working environments. They will not experience performance degradation due to prolonged use. In addition, the corrosion resistance of SUS631 can also work in humid and chemical environments. The surface of Pogo pin is not easily corroded, further extending its service life.
The impact of SUS631 raw materials on the cost-effectiveness of Pogo pins
Cost composition (increasing factors):
High material cost: Johoty commonly uses SUS631 as precipitation hardening stainless steel, which contains nickel, chromium, aluminum, etc. The procurement cost of raw materials is about 3-5 times that of ordinary SUS304 stainless steel.
Increased processing costs: This raw material must undergo strict heat treatment to achieve optimal performance. Quenching and tempering, solution treatment, adjustment treatment, and age hardening. This increases energy consumption and time costs, placing higher demands on spring process control.
Tool wear: After heat treatment, the hardness of the raw material is extremely high, reaching HRC ≥ 44. In subsequent grinding and cutting, it will accelerate the wear of molds and cutting tools, indirectly pushing up production costs.
Benefit advantage (value return):
Ultra long fatigue life: Under precise heat treatment, SUS631 springs can achieve a compression life of over 1 million cycles. Far higher than the 200,000 to 500,000 cycles of SUS304 or the 500,000 to 800,000 cycles of SWP. This significantly reduces the failure rate and replacement frequency in high-frequency plugging and unplugging. Johoty’s pogo pin will be more suitable for your testing fixtures, precision instruments, and automation equipment.
Excellent reliability: Johoty’s POGO pins based on SUS631 have excellent stress relaxation resistance and maintain stable contact force during long-term use. Customers have repeatedly verified and produced proof that they can avoid poor contact caused by elastic attenuation. Ensure the stability of 5G communication and medical equipment signal transmission.
Built in corrosion resistance: SUS631 raw material also has good corrosion resistance. In most environments, surface treatment processes such as gold plating can be eliminated. Save costs and avoid the risk of failure caused by coating wear and oxidation.
Support for miniaturization design: Ultra high strength allows for the design of smaller wire diameters and volumes under the same load. Helps to achieve compactness of pogo pin connectors. Adapt to the trend of lightweight consumer electronics and save raw material usage.
Comprehensive cost-benefit analysis:
High end applications: In automotive electronics, aerospace, precision instruments, and high-end medical equipment, product reliability is given much higher priority than initial cost. The use of SUS631 raw materials can effectively reduce hidden costs such as after-sales maintenance and brand reputation risks. Its TCO is actually lower, with a clear cost-effectiveness advantage.
Ordinary consumer electronics: For ordinary Bluetooth earphones with a short lifespan and low requirements for plugging and unplugging, their performance advantages cannot be fully utilized. Choosing materials such as SUS304 or SWP is a more economical option.
