304 is a common stainless steel, which is widely used for widely used in Production requirements 
Equipment and parts of good comprehensive performance ( corrosion resistance and moldability ). In order to maintain the inherent corrosion resistance of stainless steel, steel must contain more than 18%chromium and more than 8%nickel content. 304 stainless steel is a brand of stainless steel produced according to the American ASTM standard. and 304 Stainless steel is also a common material for salt fog test testing, which can be at least 48 Hours salt salt Fog tests can be called qualified.
Test standards: the unified regulations made for repetitive things and overview. The salt fog test standard is to make the salt fog test conditions, such as temperature, humidity, sodium chloride solution concentration and pH value, etc., and also propose technical requirements for the performance of the salt fog test box. Which salt fog test standards are used in the same product, according to the characteristics of the salt and mist test, the corrosion speed of the metal and the sensitivity to salt mist.
Preparation of salt fog test solution: dissolved GR (high -quality pure) sodium chloride
(1) The dissolved solid amount is less than 200 ppm), and the test solution is mixed into a test solution with a concentration of 5%. When the solution is (35 ± 2) ° C, the pH should be within 6.5 ~ 7.2.
(2) After spraying this test solution at 35 ° C, the pH value of the collection solution should be 6.5 ~ 7.2.
(3) Before spraying, this test solution cannot contain suspension.
(4) Note: Sodium chloride does not contain non -pure objects of copper and nickel, and the content of sodium iodide in the solid must be less than 0.1%.
AOTSI salt fog test box, also known as salt water spray test machine, salt fog test machine, salt fog test box as an artificial climate environment One of the test equipment of the test equipment of three defense (damp -heat, salt, mist, and mold) is an important advantage of researching machinery, defense industry, light industry electronics, instrumentation and other industries such as various environmental adaptability and reliability: corrosion corrosion The environment can be controlled, the environment is good; the test time is significantly shortened; it saves a lot of manpower, financial resources, and material resources. Perform electroplating, coating, etc. with the product salt mist corrosion test .
