Q
What is the difference between 304 stainless steel and 316 stainless steel? How to choose?
304 stainless steel: Contains 18% chromium and 8% nickel. It has good corrosion resistance and processability, and is suitable for ordinary industrial environments (such as dry, weak acid, and weak alkali scenarios).
316 stainless steel: Added with 2% molybdenum, which significantly improves the resistance to chloride ion corrosion. It is ideal for highly corrosive environments such as marine and chemical industries (such as seawater, acid mist, and salt spray).
Q
How is the corrosion resistance of the STAINLESS STEEL ENCLOSURE tested?
Salt spray test: Simulating the marine environment, the test standard is ASTM B117 (for example, 316 stainless steel needs to pass ≥96 hours of testing without rust).
Chemical immersion test: Immerse the sample in a specific acid-base solution (such as 5% sulfuric acid, 10% hydrochloric acid) and observe the surface changes.
Q
Is the STAINLESS STEEL ENCLOSURE suitable for high or low-temperature environments?
Yes, it is highly suitable for extreme temperatures:
High-temperature environment: Stainless steel can withstand temperatures up to 800°C (short-term), and it is recommended to use it at ≤300°C for long-term use.
Low-temperature environment: It remains tough at -60°C, suitable for cold storage, polar equipment, etc.
Note: For extreme temperatures, it is necessary to use temperature-resistant sealing rings (such as fluororubber).
Q
What should be paid attention to when installing the STAINLESS STEEL ENCLOSURE?
1. When installing the STAINLESS STEEL ENCLOSURE, avoid direct contact with carbon steel (to prevent electrochemical corrosion) and use insulating gaskets.
2. The grounding terminal must be reliably connected (grounding resistance ≤4Ω).
3. For outdoor installation, the box should be tilted by more than 5° for drainage.
Q
What is the protection rating (IP grade) of this enclosure?
The shell features an IP56 protection grade, which provides excellent protection against dust ingress and powerful water jets, ensuring stable performance in harsh environments.
Q
What quality standards and certifications does the enclosure comply with?
The product complies with international and domestic quality standards and has successfully passed certifications including ISO9001:2000, VDE, and CCC.
