When the fasteners are selected, whether the stainless steel material is magnetic or not does not indicate the quality of the fasteners. In fact, some chromium-manganese stainless steels are stainless steels that do not have magnetic properties. Chromium-manganese stainless steel in stainless steel fasteners is not a substitute for the use of 300 series stainless steels, especially in high-media corrosive working environments. Regardless of the manufacturing, use or handling of the various...
Due to the essential difference between stainless steel and carbon steel, stainless steel has good ductility. If it is used improperly, it will easily lead to the screw and the nut can not be unscrewed, which is commonly called “locking” or “biting dead”. The main improvement is as follows: A: The correct choice of products: confirm that the mechanical properties should meet the requirements, the length to tighten the 1-2 teeth saw after the nut is exposed. Second: Correctly reduce the friction...
1. Correct selection of products: Before use, confirm whether the mechanical properties of the product can meet the requirements of use, such as the tensile strength of the screw and the guaranteed load of the nut. The length of the screw should be properly selected to tighten the nut and expose the nut 1-2 teeth. 2, check whether the thread is rough before use, whether there is iron filings or dirt between the threads, these things often lead to lock. 3, the fastener can be lubricated before...
Fastener users often reflect why stainless steel fasteners sometimes have locking problems, and similar phenomena do not occur when using carbon steel fasteners. Is stainless steel fasteners softer, carbon steel? The reason why fasteners are relatively hard? Yes! Stainless steel and carbon steel are essentially different. Stainless steel has good ductility, but its hardness has a certain gap with carbon steel. However, this statement can only be said to be half right. Locking often occurs on...
Stainless steel standard parts are mainly made of stainless steel wire as raw material, followed by a series of processes such as the steps of producing standard parts. It is very popular to manufacture fastener products using stainless steel, but for stainless steel fasteners, It has four major performance points, which are described as follows: First, the high temperature resistance of stainless steel fasteners. Because the hardness of stainless steel itself is relatively strong, the...
Fasteners use stainless steel as the material, which can be said to have great advantages in all aspects of manufacturing, use or handling. Therefore, although the fasteners are made of stainless steel, the cost is relatively high, and the cycle life is relatively short, but it is tight. The firmware solution is still a more economical one. Stainless steel magnetic problem of fasteners If the fasteners use stainless steel as the main material, you should also understand the magnetic problems of...

Core Tip: Fasteners are the basic parts of hardware machinery. The demand is very large. In certain occasions, the fastener materials need to meet the conditions of severe corrosion or high strength. Many stainless steel and ultra-high-strength stainless steels have emerged, so tighten. How to choose stainless steel wire? Fasteners are hardware mechanical basic parts, which are in great demand. Usually bolts, screws, rivets, etc. are used to ensure safety or generally do not consider the...

It is well known that stainless steel is less machinable than medium carbon steel. With the development of the equipment manufacturing industry, stainless steel fasteners are increasingly used in all walks of life. The processing and manufacturing technology of stainless steel fasteners is gradually becoming more mature. Each enterprise should select the appropriate blade material when processing stainless steel according to its actual needs, and the cutting amount should be used to achieve the...

It is used to improve the surface of stainless steel products, producing a shiny surface, greater strength and excellent corrosion resistance without affecting the external dimensions of the fastener. Foreverbolt NL-19 Surface Treatment is an advanced corrosion protection method that significantly reduces future maintenance costs. The founder of the company, Patrick Vogel, explained: "The...
When the normal operating temperature of the heat exchanger reaches 1000°F (about 283°C), the bolt made of stainless steel is rusted! Why is this? Originally, at higher temperatures, the thermal cycle will change some stainless steel. Non-stainless steel. Therefore, the selection of fastener materials must be careful to avoid accidents. Stainless steel background: According to the definition, the chromium content of stainless steel should be not less than 10.5%, but the author believes that...
Material selection principle The choice of stainless steel materials is mainly considered from the following five aspects. 1. Requirements for mechanical properties, especially strength, of fastener materials. 2. Requirements for the corrosion resistance of the material under working conditions. 3, the working temperature on the material's heat resistance (high temperature strength, oxidation resistance) requirements. 4. Requirements for material processing performance in terms of...
