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.

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 |

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.
