Two problems that may occur during the use of titanium alloy screws
The importance of screws in our lives and work is self-evident. Screws are a very large category. There are many different types of materials depending on the type and material.
Among them, the titanium alloy screw should be a kind of fastener which is used frequently in the moment, and its appearance also has a very good texture, and the strength and corrosion resistance also have a good point.
Of course, in some scenarios, titanium alloy screws can not meet the requirements, so under the process of some heat treatment and electroplating, the titanium alloy screws can show better performance and can be 100% recycled. This avoids wasting resources.
Of course, in many high-end industries, stainless steel materials can no longer meet the demand, so the appearance of titanium alloy and titanium screw fasteners make up for some vacancies.
Of course, the mainstream of fasteners is still made of stainless steel. After all, the process is mature, and the cost of materials is relatively cheap. It is one of the better choices for most users. Let's take a brief look at the use of fasteners. Two problems encountered.
Question about magnetism
In our understanding, titanium alloys are not magnetic, but in fact, titanium alloy screws can exhibit some magnetic properties after some simple processing, so if the quality of fasteners is judged by magnetism Or materials and so on are very inaccurate.
When the titanium alloy screws are selected, whether the stainless steel material has magnetic properties does not indicate the quality of the titanium alloy. In fact, some chromium-manganese stainless steels are stainless steels that do not have magnetic properties.
Chromium-manganese stainless steel in titanium alloy screws is not a substitute for the use of 300 series stainless steel, especially in high-media corrosive working environments.
Use of nickel in fasteners
Fasteners used to rely on the use of nickel in the process of using stainless steel, but the price of fasteners has also been greatly affected by the global price of nickel.
In order to reduce the cost pressure and improve the competitiveness of the screws, the screw manufacturers have found alternative materials and produced low-nickel titanium alloy screws.
