Heat resistant and anti-corrosion RFID tag SteelHT

RTEC SteelHT is chemical resistant RFID tag with integration of injection molding. Integrated injection molding makes the tag as a whole without any gaps. The ceramic substrate and the integrated injection molding make this hard tag not only resistant to high temperature, but also anti-corrosion, and any acid and alkali solution will not enter the inside of the tag. Therefore, SteelHT is a combination of long range passive RFID tag, most rugged RFID tag, ultra high temperature RFID tag, most durable RFID tag, and anti-corrosion RFID tag. This uhf tag is truly the best solution for RFID in manufacturing industries.

Product Description

Corrosion is a common issue in industries where assets are exposed to harsh environmental conditions such as marine, chemical processing, and oil and gas. To combat this challenge, chemical resistant RFID tag has been developed with materials and coatings that are resistant to corrosion. This is the reason SteelHT is invented. SteelHT, the chemical resistant RFID tag is designed to withstand exposure to moisture, salt, and corrosive agents, ensuring reliable performance and durability in demanding environments. The use of anti-corrosion RFID tags has proven to be beneficial in asset management and inventory tracking applications, where the tags are deployed on equipment, tools, and components that are susceptible to corrosion.
Meanwhile, SteelHT is also a RFID hard tag, the shell is strong against pressure and collision. In a complex industrial environment, bumps and bruises are inevitable, and Steelht, as an anti-corrosion RFID tag, has a certain anti-impact function, and will not be easily damaged by impact.   
In industrial settings such as manufacturing, automotive, and aerospace, there is a growing need for RFID tags that can withstand high-temperature environments without compromising performance. Traditional RFID tags may not be suitable for applications where exposure to extreme heat is a constant factor. As High-temperature RFID tags, SteelHT are specifically designed to operate reliably in environments where temperatures can surpass the limits of standard RFID tags. These durable RFID tags are constructed using heat-resistant materials and components, allowing them to withstand temperatures ranging from 200°C to 300°C or higher. Heat resistant RFID tags have proven to be invaluable in applications such as industrial ovens, paint curing processes, and high-temperature manufacturing operations, where conventional RFID tags would fail or degrade under extreme heat conditions.
The integration of anti-corrosion, anti-collision, and high-temperature RFID tags has revolutionized the way industries manage and track assets, inventory, and processes. The benefits of Steelht extend beyond improved performance and durability, influencing operational efficiency, quality control, and data accuracy. As the demand for RFID technology in challenging environments continues to grow, it is essential for industries to leverage the capabilities of these innovative RFID tags to optimize their operations and gain a competitive advantage.
RTEC, one of the best RFID tag companies will always strive for further innovations in specialized RFID tags, offering solutions to address new challenges and drive continued advancements in various industries.


How to package the tags? 
SteelHT is a RFID uhf tag heavy duty rugged type, it is quite large and heavy, therefore we will pack them in small group with antistatic bag and then pack them in boxes.

Can I customize this RFID high temperature on metal tag’s color?
Yes, but SteelHT is a high temperature RFID tag. Most of the high temperature resistant plastics are black, the shell material can not be changed. But you can change the appearance color by spraying high temperature resistant paint. At present we have silver and white high temperature resistant paint.

Can I customize the surface engraving content of the temperature resistant RFID tag?
Yes, we can engrave logo, barcode, QR code, serial number ect.
