Stainless steel screws corrosion rust and fracture reason analysis

Stainless steel screws corrosion rust and fracture reason analysis

Stainless steel screw corrosion rust

Stainless steel screws are necessarily not corrosion and rust, just that stainless steel screws, relative to iron screws, carry corrosion, and rust ability is a little more robust. But stainless steel screws in specific circumstances or rust. Then stainless steel screws in what conditions easily lead to rust! What is the reason for rust?

Stainless steel screws have better characteristics, a solid ability to carry corrosion and high-temperature resistance, but they also have a robust anti-rust performance. However, it will still rust in harsh environments. For example, stainless steel screws in a very humid situation, sun, and wind every day, wind and rain. For a long time, more or less sure to rust， For example, some acid and alkali chemicals are in contact, so the chemical reaction. Lead to corrosion and rust. There are also initially wrong stainless steel screws, such as the material for stainless steel SUS201 screws used in seawater products; due to prolonged immersion, originally SUS201 stainless steel screws itself are not very suitable for seawater has a vital salt above the use. They are resulting in corrosion and rust. In the use of seawater products above, they are generally recommended to use stainless steel SUS316 screws because 316 stainless steel screws carry corrosion and other properties better.

From the above can be concluded that stainless steel screws, in specific circumstances, or corrosion and rust. Therefore, this requires the rational use of stainless steel screws. In different circumstances, the use of other materials of stainless steel screws.And on various occasions, in the use of stainless steel screws, we also need to pay special attention to some details of the problem, have to consider more. As far as possible, the stainless steel screw corrosion rust control.

Stainless steel screw breakage cause analysis

Sometimes, from time to time, we see iron screws break, and other times, we also see stainless steel screws break. But generally speaking, stainless steel screws are rarely broken. Because the stainless steel screw wire itself is relatively complex, but in specific circumstances, stainless steel screws will still break. So what are the main reasons for stainless steel screws to break!

The reasons for stainless steel screw breakage are as follows:

1. Stainless steel screws used in the quality of raw materials, stainless steel screw wire quality is not good. There are a lot of impurities, impure, resulting in stainless steel screw hardness is not enough.

2. Production of stainless steel screw process problems. For example, eccentric head eccentric stainless steel screws, as well as the production of manufacturing under the punch operation Q value, are too deep, and the R bit design is too small.

3. Industrial manufacturing connections in the use of stainless steel screws, too much force. Generally, you do the following torque test to see the minimum breaking force for how much and then adjust the torque.

Of course, the stainless steel screw breakage is undoubtedly more than the above three reasons. But the above three reasons are the main reasons for stainless steel screw breakage. When you find the stainless steel screw breakage, you can check it step by step.
