How to avoid biting between stainless steel screws and stainless steel nuts!
Why can't stainless steel screws and stainless steel nuts be used together? This is mainly due to the material of stainless steel. When stainless steel screws are tightened with stainless steel bolts and nuts during the assembly of low-temperature pipeline flanges, they often bite and become difficult to remove.

So generally, stainless steel screw manufacturers do not recommend using stainless steel screws and stainless steel nuts together. So, if stainless steel screws and stainless steel nuts are used together, what aspects should we solve the problem of biting?
1. It is possible to perform cryogenic treatment by immersing stainless steel screws into a low-temperature liquid nitrogen box to moisturize for a certain period of time, in order to reduce deformation caused by temperature differences and changes in metallographic structure, thereby improving the sealing performance of the valve at low temperatures.
2. Replace the stainless steel nut with another material, or replace the basic one with another material. This avoids the phenomenon of stainless steel bolts and stainless steel nuts biting together
3. There is currently another technology, which is a biting agent that can prevent screws and nuts from biting,
4. When using stainless steel screws and nuts, apply some lubricating grease on the stainless steel screws to avoid the phenomenon of stainless steel screws biting.
