Service Hotline304L stainless steel cold pier line, 304 stainless steel cold pier line, 310 stainless steel cold pier line, 303 stainless steel cold pier line, 302 stainless steel cold pier line, 301 stainless steel cold pier line, 202 stainless steel cold pier line, 201 stainless steel cold pier line, 410 stainless steel Cold pier line, 420 stainless steel cold pier line, 430 stainless steel cold pier line, 316L stainless steel cold pier line: 316 stainless steel contains molybdenum and low carbon content, and its resistance to pitting corrosion in marine and chemical industry environments is much better than 304 Stainless steel! (316L low carbon, 316N nitrogen high strength and high strength, 316F stainless steel with high sulfur content, easy to cut stainless steel [1]. 304L stainless steel cold pier wire: as a low carbon 304 steel, in general, the corrosion resistance is the same as 304. Similar, but after welding or after stress relief, its resistance to grain boundary corrosion is excellent, and it can maintain good corrosion resistance without heat treatment. 304 stainless steel cold pier wire: has good corrosion resistance, heat resistance High temperature resistance, low temperature strength and mechanical properties, good thermal processability such as stamping and bending, no heat treatment hardening phenomenon. Uses: tableware, cabinets, boilers, auto parts, medical appliances, building materials, food industry (use temperature -196°C-700° C) 310 stainless steel cold pier wire: The main features are: high temperature resistance, generally used in boilers, automobile exhaust pipes. Other properties are average. 303 stainless steel cold pier wire: By adding a small amount of sulfur and phosphorus, it is easier to cut than 304, Other properties are similar to 304. 302 stainless steel cold pier wire: 302 stainless steel bar is widely used in auto parts, aviation, aerospace hardware tools, chemical industry. The details are as follows: handicrafts, bearings, slippery, medical equipment, electrical appliances, etc. Features: 302 stainless steel The ball is austenitic steel, which is close to 304, but the hardness of 302 is higher, HRC≤28, and has good rust and corrosion resistance. 301 stainless steel cold pier wire: good ductility, used for forming products. Machining makes it harden quickly. Good weldability. Wear resistance and fatigue strength are better than 304 stainless steel. 202 stainless steel cold pier wire: belongs to chromium-nickel-manganese austenitic stainless steel, and its performance is better than 201 stainless steel cold pier wire Shenzhen Global Stainless Steel Cold Pier Wire 201 Stainless Steel Cold Pier Wire: It belongs to chromium-nickel-manganese austenitic stainless steel, with low magnetic properties. 410 stainless steel cold pier wire: belongs to martensitic (high-strength chromium steel), with good wear resistance and corrosion resistance Poor performance. 420 stainless steel cold pier wire: cutting tool grade martensitic steel, similar to Brinell high chromium steel, the earliest stainless steel. It is also used for surgical knives and can be made very bright. 430 stainless steel cold pier wire: Ferritic stainless steel, decorative, e.g. for car accessories. Good formability, but poor temperature and corrosion resistance
Nuts and bolts are one of the most widely used fasteners in modern mechanical structures. At present, the common metric bolts and nuts are generally trapezoidal in cross-section. The connection between the bolt and the nut is prone to loosening under severe vibration, or even falls off by itself, and the tightening force of the bolt and nut thread is mainly concentrated in the bolt thread and Between the teeth of the first few threads where the threads of the nut are in contact, resulting in loosening of the fastener and sliding pressure of the threads
Fasteners are widely used in nuclear power plant safety systems and equipment, and undertake the functions of component connection, pressure sealing box support and fixation, and their quality and performance play an important role in nuclear power plant safety systems and equipment performing nuclear safety functions. None of the special fasteners for nuclear power in the prior art have protective sleeves, which cannot protect the exposed part of the bolt shank. In order to solve the above difficulties, it is necessary to develop a fastener stud nut washer set that can protect the exposed part of the bolt shank.
The height of the existing assembly devices is fixed, and the height of the workers is different, so it is very inconvenient to use, resulting in a decrease in efficiency. With the progress of science and technology and the development of society, people have proposed higher assembly devices. Therefore, we propose a shaft card assembly device to solve the above problems.
With the development of the economy, automobiles have become an indispensable means of transportation in people's lives, and the production, sales and after-sales services of automobiles have also developed rapidly. Automobile wheels and steel rings are an important part of auto parts and are also related to The use of the car is safe. The connection between the car wheel and the steel ring is realized by bolts, so the bolts and nuts need to have good fixation.
We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: national standard slider nuts, stop serrated washers, square wing wing nuts, flat head round head large flat head machine thread nuts and other products, we can provide You have the right fastener solution for you.
