Is it the quality problem or reasonable for the rust of stainless steel special custom screw? Many friends may ask this question. In fact, stainless steel screw is not never corroded to rust. Just relative to the iron screw, corrosion resistance of stainless steel screw is a little bit stronger. But in certain cases, stainless steel screw will rust. Well, under what conditions stainless steel special custom screw can easily lead to rust? What is the cause of the rust?

The characteristics of stainless steel screw are better. It has the strong corrosion ability,  resistance to high temperature, and the strong rust prevention performance. But under the harsh environment, it will rust. For example, in the case of moist, stainless steel screw often suffers the and rain. It will certainly have some rust over time. Another example, contacting with some acid and alkali chemical makes it produce chemical reaction and lead to corrosion and rust. Also, due to the long soaking time, the product used in seawater whose material is SUS201 stainless steel screw is easily corroded, because SUS201 stainless steel screw is not suitable for use in the salty seawater. In the use of Marine products , generally we advice to use SUS316 stainless steel screw, because it has better corrosion resistant performance.

From the above can be concluded that in certain cases, stainless steel special custom screw will rust. So, it requires that we should use stainless steel screw reasonably.
