Reasons For Stainless Steel Screw Fracture And Differences From Carbon Steel Screws

Stainless steel screws refer to steel screws that have the ability to resist corrosion from air, water, acid, alkali salts, or other media. According to the different alloy compositions, stainless steel screws focus on rust resistance or acid resistance. However, what is the reason for the breakage of stainless steel screws?

The fatigue strength, material quality, heat treatment process, and manufacturing process of screws directly affect the fracture of stainless steel screws. When these factors are standardized, the fracture of stainless steel screws is mostly caused by looseness.
The problem of loosening and fracture of stainless steel screws is similar to fatigue fracture, and we can often find the root cause of the problem from the fatigue strength. In fact, stainless steel screws rarely encounter situations where fatigue strength needs to be considered during use.
The reason for damage caused by loose screws: This huge kinetic energy directly acts on fasteners and equipment, resulting in fastener damage. After the fasteners are damaged, the equipment cannot function properly, further leading to equipment damage. Fasteners subjected to axial forces may damage threads or break bolts, while fasteners subjected to radial forces may cause bolt shear or deformation of bolt holes. Choosing a thread locking method with excellent anti loosening effect is the key to solving the problem.
Stainless steel screws and carbon steel screws are common fasteners and widely used types of screws. They have their own characteristics, let's understand the differences between them:
1. Carbon steel screws are steel without special alloying elements added, while stainless steel screws achieve rust prevention performance by adding high alloy content steel.
2. The price of stainless steel screws is much higher than that of carbon steel screws, mainly due to the higher cost of stainless steel materials. The performance of stainless steel material is better than that of carbon steel material, so the price is directly proportional to the quality.
3. These two types of screws have different application fields and cannot be simply compared in terms of superiority or inferiority. Carbon steel screws typically have higher strength, but are prone to rusting.
4. Stainless steel screws and carbon steel screws are made of different materials, using stainless steel and carbon steel materials respectively. Stainless steel materials include austenitic stainless steel, ferritic stainless steel, martensitic stainless steel, and precipitation hardening stainless steel, while carbon steel materials include various types such as low carbon steel, medium carbon steel, and high carbon steel screws.
