GB Half Thread Hexagon Head ss304 ss316 M4-M36 Thumb Bolts And Screw
Product Description
Stainless steel usually refers to steel with resistance to air, water, acid, alkali salt or other medium corrosion. According to the different composition of the alloy, respectively, focusing on stainless steel and acid resistance. Some steel, although with a stainless steel, but not necessarily acid, acid-resistant steel is usually a stainless steel. For the production of fasteners are mainly austenitic stainless steel, in people's daily life, often referred to as stainless steel is also austenitic stainless steel. We use the stainless steel fasteners, raw materials are mainly used austenitic 302,304,316 and "low nickel" 201 and so on.
Stainless steel screw selection principle:
The choice of stainless steel material mainly from the following
five aspects to consider.
1, the stainless steel screw material in terms of mechanical
properties, especially strong
The requirements of the degree;
2, working conditions on the material corrosion resistance
requirements;
3, the working temperature of the material heat resistance (high
temperature strength, oxidation resistance) requirements;
4, the production process on the material processing performance
requirements;
5, other aspects, such as weight, price, procurement and many other
factors to be considered.

Application
Hex bolts can be used for many different applications that include fastening wood, steel, and other construction materials for projects such as docks, bridges, highway structures, and buildings. Hex bolts with forged heads are also commonly used as headed anchor bolts.
Stainless steel screws are not necessarily not corroded rust, but
that stainless steel screws relative to the iron screws to carry
corrosion and rust ability a little stronger. But the stainless
steel screws will rust in a particular situation. Then the
stainless steel screws under what conditions easily lead to rust
it! What is the reason for rust.
Stainless steel screws are better characteristics, have a strong
ability to carry corrosion, high temperature performance, but also
a strong anti-rust performance. But in the harsh environment will
still rust. For example, stainless steel screws in a very humid
case, every day sun shower, wind and rain. Time for a long time,
how many will certainly rusty. In contact with some acid-base
chemicals, for example, to produce a chemical reaction. Cause
corrosion rust. There is also a bad stainless steel screws, such as
the material for the stainless steel SUS201 screws in the use of
water products, due to regular soaking, originally SUS201 stainless
steel screws itself is not suitable for salt in the sea above the
strong use. Cause corrosion rust. In the use of seawater products
above the general proposal to use stainless steel SUS316 screws,
because 316 stainless steel screws carry corrosion and other
properties are better.
From the above can be obtained stainless steel screws in a
particular case, or will corrode rust. So, this requires a
reasonable use of stainless steel screws. Use different sizes of
stainless steel screws in different situations. And in different
occasions, the use of stainless steel screws, but also need special
attention, some of the details of the problem, much to consider. As
far as possible to the rust of stainless steel screw corrosion
control.
Stainless steel screws are widely used in machinery, petrochemical, communications, chemical, construction, power, textile, sports equipment, paper, sewage treatment, shipbuilding, automobile and other industries, with the domestic economic living standards greatly improved stainless steel screw applications will be more widely.
