Excessive corrosion of stainless steel screws indicates that quenching oil has been used for too long, and new oil or replacement is needed.

The product is deeply loved by different industries, but it does not mean that the birth is the popular.

But through continuous evolution and upgrading to make the product so excellent, so as to be generally used.

Technology is the main source that drives product development. Equally important is that human beings have a higher demand for products.

Stainless steel screws in the process of use need to pay attention to what problems:

First, stainless steel (stainless acid steel) screws in the screw rinsing, because this process (Guo Cheng) is very important, need to be very careful,

This process will leave residue on the surface of the screw. Stainless steel screws are usually steel that is resistant to corrosion by air, water, acid, alkali, salt or other media.

According to the different composition of the alloy, respectively focus on rust resistance and acid resistance.

Although some steels have rust resistance, but not necessarily acid resistance, acid resistance steels are usually rust resistance. Rinse this step is after the silicate cleaner cleaning.

Two, the screw should be stacked in the tempering heating process, otherwise it will lead to (cause) slight oxidation in the quenching oil.

Electrical screws are “mass products”, not handmade works of art, in mass production, in order to achieve high precision and stable quality and popular price to consumers for the purpose of supply.

Three, to the surface of the screw with particularly high strength will appear white phosphating residues, indicating that (the first point) the operation control inspection is not serious and careful.

Precision screws Small screws, also known as micro screws, are small fasteners that connect product materials.

They are small in shape, but they play a key role in the key parts of production.

Widely used in electronics, electrical, electrical appliances, furniture, mechanical equipment and so on.

Four, stainless steel (stainless acid-proof steel) screws if found on the surface of parts blackening phenomenon to produce chemical reverse.

It shows that the work of heat treatment is not done thoroughly, and the alkaline residues on the surface are not completely removed.

Five, the standard parts of the parts will rust in the rinsing, the water used for rinsing should often be replaced.

The stainless steel screw products are so popular, because it can cater to the development of human preferences.

And human progress and the development of science and technology cannot do without, but also led to the continuous improvement of product performance.

Now the manufacturer of the product is everywhere, so it is necessary to make a full understanding of the purchase before determining.
