Stainless Steel 3/8 7/16 1/2 Flat head solid rivet custom SUS 304 SUS 316 Round head rivets


 
 
Product Description:
A method of connecting two or more parts by using axial force to thicken the rivets in the rivet holes of the parts and form a nail head.
Riveting in 3000 BC has been new, the earliest discovery of riveting originated in Egypt, used in the manufacture of wooden tools, and later wood rivets were used for fastening, the Vikings in the 7th and 8th centuries AD in their ships were also used to the wood rivets, the use of wood rivets has been extended to the early 19th century, the development of the steel industry to solve the problem of wood rivets are easy to crack the rivets of the use of metal to make the structure stronger, even when riveting thick materials. From that time onwards, other joining technologies are also developing rapidly, but until now, riveting technology is still widely used in material joining applications, including aviation, aerospace, marine, vehicles, air conditioning, furniture and so on.
 
Solid round head rivets
This is one of the oldest and most reliable forms of fastening and was used during the Bronze Age. The basic components of this type of rivet include a shaft and a head, which are riveted by a hammer or a rivet gun, and it is also possible to rivet this type of rivet by means of press fitting.
 
Rivets are commonly used in applications requiring high reliability and safety, such as aircraft, and some craftsmen have used solid rivets in the manufacture of medieval armour, jewellery and metal decorations.
High-strength structural steel rivets have been gradually replaced by high-strength bolts in the process of technological development, the main reason is that the installation of high-strength structural steel rivets requires skilled labour to riveting, while the general high-strength bolts can be installed by the average worker with only simple training.
 
In riveting, the use of its own deformation or interference to connect the riveted parts of the parts. There are many types of rivets, and not in any form. Commonly, there are semi-circular head rivets, flat head rivets, countersunk head rivets, semi-hollow rivets, solid rivets, sub-mother rivets, step rivets and so on.
 
 
Round head rivets are mainly used with the larger lateral load riveting occasions, the most widely used.
Flat cone head rivets due to fat nail head, corrosion resistance, commonly used in ship hulls, boiler tanks and other corrosive strong riveting occasions.
Countersunk head, 1200 countersunk head rivets are mainly used for the surface must be smooth, with the load is not big riveting occasions.
Semi-countersunk head, 1200 semi-countersunk head rivets are mainly used for smooth surface, with the load is not big riveting occasions.
 
Flat Head Rivets
Flat head rivets are primarily used on metal exterior surfaces that often require a better appearance and the elimination of unwanted air resistance.
Flat head rivets are generally fitted inside countersunk holes, hence the name countersunk head rivets, and are often used in the external mounting of aircraft.
 
Applications:Stainless Steel:
1, the basic knowledge of stainless steel
Stainless steel is an alloy material with corrosion resistance, and its main components are an alloy of elements such as iron, chromium and nickel. These elements can effectively resist oxidation and corrosion, so that stainless steel has a high degree of durability and aesthetics.
2, stainless steel maintenance methods
Cleaning
Keeping stainless steel products clean is an important part of their maintenance. You can use mild detergents and soft cloth for cleaning, avoid the use of detergents containing acidic and alkaline components, so as not to damage the surface of stainless steel. When removing dirt, you should try to avoid using irritating cleaning tools to avoid scratching the stainless steel surface. After cleaning, rinse with water and dry with a clean soft cloth.
3, the use of stain remover
For some stubborn dirt, you can use special stainless steel stain remover for cleaning. But before using it, you should carefully read and follow the instructions in the product manual. In addition, stainless steel products on the dirt can be cleaned with alcohol or vinegar, these common cleaners on stainless steel has a certain decontamination effect.
Steel types:

 
201, 304, 316 are austenitic stainless steel, according to the performance of the non-magnetic, some of the performance of the weak magnetic because of the smelting of the composition of the segregation or improper heat treatment leads to the austenite in a small amount of martensite or ferrite. Austenitic stainless steel corrosion resistance comes from the formation of chromium oxide protective layer on the metal surface. When the material temperature is heated to 450 degrees -900 degrees, the structure changes, will form chromium carbide along the edge of the crystal and can not form a protective layer of chromium oxide, thus reducing the corrosion resistance, this is also known as ‘intergranular corrosion’. As a result, there are 304L and 316L, the two due to the low carbon content also reduces the intergranular corrosion. In particular, the higher susceptibility to intergranular corrosion does not mean that non-low carbon content is more susceptible to corrosion, in a highly chlorinated environment, this susceptibility is also higher.
 
Resistant to air, steam, water and other weak corrosive media or stainless steel, such as 201 (1Cr17Mn6Ni5N), 202 and other 2 series of steel; and will be resistant to chemical corrosive media (acids, alkalis, salts, etc.) corrosion of the steel to become acid-resistant steel, such as 304 (06Cr19Ni10), 316 (0Cr17Ni12Mo2), and so on, 3 series of steel. Because of the differences in chemical composition of the two resulting in their ability to resist corrosion is different, like 2 series of stainless steel is generally not resistant to corrosion of chemical media, and 3 series of stainless steel have the ability to resist corrosion of chemical media.
