FAQ

1. What are the main differences in performance between stainless steel and 316 junction boxes?
They have good corrosion resistance and comprehensive performance, can cope with corrosion in most common environments, and are relatively low in cost. They add molybdenum to 304, and have stronger corrosion resistance, especially in chloride-containing environments (such as the seaside and chemical workshops), and have stronger resistance to pitting and crevice corrosion, but the cost is also relatively high.

2. How is the protection level of junction boxes reflected?
Answer: The common protection level of junction boxes is expressed by IP codes (such as IP65, IP67) or NEMA grades (such as NEMA 4X). In the IP code, the first number indicates the dustproof level, and the larger the number, the stronger the dustproof ability; the second number indicates the waterproof level, and the larger the number, the better the waterproof ability. The NEMA 4X grade means that the junction box is dustproof, waterproof, and corrosion-resistant, and can be used in a variety of harsh environments.

3. What are the strength advantages of stainless steel junction boxes compared to junction boxes made of other materials?
Stainless steel itself has high strength and hardness. Steel junction boxes can withstand large external impacts and extrusions without being easily deformed. Compared with plastic junction boxes, it is more durable and can better protect the internal electrical components; compared with some ordinary metal junction boxes, they have better corrosion resistance. During long-term use, the strength will not drop significantly due to corrosion, and can continuously ensure the safety and stability of electrical connections.
