Stainless Steel Male And Female Hexagon Head Standoff Plain Polishing Passivate single studs

Stainless Steel Male And Female Hexagon Head Standoff Plain Polishing Passivate single studs
 
Product Description:
What is a standoff? As the name suggests, tstandoff is one end for the internal thread and the other end for the external thread of a kind of screws, broadly speaking, standoff also include both ends are internal thread screws. Its appearance is hexagonal, play a role in fastening and isolation, because it is generally used hexagonal copper rod as raw material production and become, so tstandoff is also known as copper column, hexagonal copper column, copper isolation column or copper spacer column.
The use of standoff. Intercalated screws are mainly used in the computer, circuit board and other industries, when one end is screwed into the locked object, the hexagonal post is exposed to the outside, which can fix or isolate other objects.
The main specifications of standoff are M3, M4, M5, M6, M8, M10, etc., and their hexagonal posts were 5, 6, 8, 10, 12, 15mm, etc., which should be in the most or the M3 series. Material in addition to copper an
 
 
Hexagonal studs are also known as yin and yang studs, it is one end of the internal thread and one end of the external thread, but are hexagonal, can play a role in fastening and isolation.
Mostly used in computers, circuit boards and other industries, when used, when one end is screwed into the workpiece being fastened, the hexagonal column is exposed on the surface, can be fixed or isolated from other workpieces. Such as in the computer mainframe, the external thread can be connected to the motherboard inside the mainframe, the internal thread can be isolated from the motherboard and sheet metal shell.
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.
 
304 stainless steel
304 is a general-purpose stainless steel that is widely used to make equipment and machine parts that require good all-round performance (corrosion resistance and formability). In order to maintain the corrosion resistance inherent in stainless steel, the steel must contain more than 18% chromium, more than 8% nickel content. 304 stainless steel is a grade of stainless steel produced according to the American ASTM standard.
 
The difference between stainless steel and carbon steel
Stainless steel and carbon steel belong to steel, but because it contains other elements are different, so there is a difference in nature, usually only contains carbon elements of steel is known as carbon steel, while the stainless steel contains other alloy materials, it's corrosion, wear resistance is very good, the difference between the two are mainly the following four points:
1, different density
The density of carbon steel is slightly higher than ferritic and martensitic stainless steel, and slightly lower than austenitic stainless steel.
2, different composition
Stainless steel (Stainless Steel) is the abbreviation of stainless acid-resistant steel, air, steam, water and other weak corrosive media or stainless steel is called stainless steel; and will be resistant to chemical corrosive media (acids, alkalis, salts, and other chemical impregnation) corrosion of the steel is called acid-resistant steel.
Carbon steel is an iron-carbon alloy with a carbon content of 0.0218% to 2.11%. Also called carbon steel. It also generally contains small amounts of silicon, manganese, sulphur and phosphorus.
