Latest company news about Environmental Reliability of Metal Materials

When metal materials are used in the natural environment, rust and corrosion will occur due to natural temperature, humidity, air, rain and other factors.


Environmental reliability generally refers to the performance of materials or products to withstand the aging and corrosion effects of various environmental factors, including climate environmental reliability and mechanical environmental reliability. Environmental reliability is mainly used to simulate the production and transportation of materials or products And whether it meets the design requirements under actual working conditions.


Environmental reliability test:
Resistant to light aging
Xenon lamp aging
Fluorescence ultraviolet aging (UVA/UVB)


Ozone aging resistance
Ozone aging (static)
Ozone aging (dynamic)


Salt spray corrosion test
(1) The neutral salt spray test (NSS test) is the earliest accelerated corrosion test method with the widest application field.
(2) Acetate salt spray test (ASS test) is developed on the basis of neutral salt spray test.
(3) Copper salt accelerated acetic acid salt spray test (CASS test) is a kind of rapid salt spray corrosion test recently developed abroad. The test temperature is 50℃. A small amount of copper salt—copper chloride is added to the salt solution to strongly induce corrosion. . Its corrosion rate is approximately 8 times that of the NSS test
