M6 M8 Stainless Steel Male And Female Hexagon Head Standoff B8 B8M
B8T 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:
No. | C% | Cr% | Ni % | Mo % |
304 | 0.07 | 17.5-19.5 | 8.0-10.5 | / |
316 | 0.08 | 16.0-18.0 | 10.0-14.0 | 2.00-3.00 |
301 | 0.15 | 16.0-18.1 | 6-8 | / |
310 | 0.08 | 24-26 | 19-22 | / |
304L | 0.03 | 18-20 | 8-12 | / |
316L | 0.03 | 16-18 | 10-14 | 2-3 |
321 | 0.08 | 17-19 | 9-12 | / |
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.
Appearance difference between stainless steel and carbon steel
If the aesthetics of the work you are doing needs to be enhanced, the appearance of the metal must be considered.
If appearance is an important factor, it is best to choose stainless steel with a special finish.
While both can be ground and polished for a bright, lustrous appearance.
However, carbon steel requires a quick clear coat or paint after the polishing process.
If these are not applied, carbon steel will lose its lustre and eventually rust.
Cost
Another important consideration is the cost difference between carbon steel and stainless steel.
Although different steels have different costs, stainless steel is generally more expensive than carbon steel.
This is primarily due to the addition of various alloying elements to stainless steel, such as chromium, nickel, and manganese.
All these extra elements in stainless steel add to the cost compared to carbon steel.
On the other hand, carbon steel consists mainly of relatively cheaper elements of iron and carbon.
If you are on a tight budget for your project, then carbon steel may be the best option.
