Why is the CD pattern screw not made of carbon steel?

Usually the material of the CD pattern screw is made of stainless steel. Some of the higher-precision materials are made of 316 or 410. So why not use stainless steel?

Let us first look at the characteristics of stainless steel materials and carbon steel materials:

The surface of the screw produced by the quality of stainless steel material is as clean as new, has anti-rust performance and corrosion resistance, good ductility and medium plasticity, which is in line with the production requirements of CD pattern screws, and the surface of the material is usually only cleaned after the production of CD-shaped screws. . Precision screws are widely used in electronics, electrical, electrical, furniture, mechanical equipment and so on. Then we can achieve the gloss of this CD pattern screw we saw above.

Carbon steel material: The corrosion resistance and rust resistance of the screw produced by carbon steel are poor, the stretching performance is not strong, the strength of the screw is high, and the plasticity is low. For example, the CD-shaped screw produced by carbon steel is easy to cause engraving. There is a brittle crack expansion when the surface of the CD pattern screw is etched. Precision screws are referred to as small screws, also called small screws. They are tiny fasteners that connect the materials of the product. They are small in shape, but they can play a key role in the key parts of Hula. The appearance effect also has no effect on the material.

From the characteristics of the material, we can know why the CD-shaped screws do not use carbon steel.

Screws have an important task in the industry. As long as there is industry on the earth, the function of the screw is always important. Need a custom screw, contact the Shi Shi Tong screw factory.
