• Product Application

1. Engine Room Ventilation on Ships

   Adapted to the high-temperature, oily, and humid environment of engine rooms, it ensures heat dissipation and air circulation for engines and other equipment, and resists oil and gas corrosion.
2. Ventilation for Crew Living Cabins

   Used for fresh air supply and exhaust gas discharge in crew cabins, mess halls and offices, meeting personnel's breathing and comfort needs while achieving moisture and rust resistance.
3. Cargo Hold Ventilation System

   For dry cargo holds, refrigerated holds, etc., it regulates the temperature and humidity inside the holds, eliminates peculiar smells, prevents cargo from mildew or deterioration, and improves transportation safety.

• FAQ:

1. Why does stainless steel have magnetism?
   a.If a magnet doesn't attract and has no magnetism, it is genuine and of good value.   On the contrary, it is regarded as a counterfeit.   In fact, this is an extremely one-sided and unrealistic method of wrong identification.
   b.Austenitic stainless steel is non-magnetic or weakly magnetic.   Martensitic or ferritic stainless steel is magnetic.   However, when austenitic stainless steel undergoes cold working, the microstructure of the processed area will also transform into martensite.

   c.The greater the degree of processing deformation, the more martensitic transformation occurs and the greater the magnetic property.   The material of the product will not change. 

2. Why does stainless steel rust?

   a. When dust containing other metal elements or particles of dissimilar metals accumulate on the surface of stainless steel, in a humid environment, the condensate water between the adherent and the stainless steel forms a micro-battery, triggering an electrochemical reaction and damaging the protective film.   This is known as electrochemical corrosion.

   b. When organic substances such as vegetable juice, noodle soup, and phlegm adhere to the surface of stainless steel, they form organic acids in the presence of water and oxygen.   Over a long period of time, these organic acids will corrode the metal surface.

   c. The stainless steel surface adheres to substances containing acids, alkalis and salts (such as splashed alkali water and lime water during wall decoration), causing local corrosion.

   d. In polluted air (such as that containing large amounts of sulfides, carbon oxides, and nitrogen oxides), upon encountering condensation water, liquid spots of sulfuric acid, nitric acid, and acetic acid are formed, causing chemical corrosion.
