Stainless Steel ANSI AISI 304 316 Phillips Drive Cross Recessed Truss Head Screw GB973

Stainless Steel ANSI AISI 304 316 Phillips Drive Cross Recessed Truss Head Screw GB973

1,Description:

The tail of the screw is generally shown as the shape of drilling tail, the hardness of this screw is very strong, compared with ordinary screws, not only the ability to maintain better, the effect of connecting the object is very firm, for this performance of the screw, generally do not need auxiliary processing, you can directly drill a hole on the object directly to lock the object, not only very convenient to use, It can also greatly improve the efficiency of work. This kind of drilling screw can be said to be the first choice of staff in various fields.

The main purpose is to make industrial products composed of a fixed body, in the use of teeth and teeth often can not be close, too hard to lock the screw head is broken, or poor dental lock is not tight and failed to meet the conditions of use, are precision problems. Screws are "quantity products", not hand-made artworks, in mass production, in order to achieve high precision and stable quality and popular price supply to consumers for the purpose. The accuracy of the screws is usually 6g (Class 2, the US specification "IFI" is 2A teeth), and the rough screws used in construction projects are 8g (Class 3, "IFI" is 1A teeth).

4,Feature Advantage:

Stainless steel screws are made of metal, and metal corrosion prevention methods mainly have four aspects, that is, the nature of the material itself, the use of the environment, the interface of data and the environment and the improvement of metal structure design, if the use of complete corrosion resistant alloy to manufacture stainless steel screws, unless there are special needs, otherwise in the economic concept is not cost-effective, It is also impractical to completely isolate the external surface of the screw from corrosive environmental elements. Improved metal structure design can improve the impact of special circumstances in a certain situation, but the design of most stainless steel screws can not be fully corrected, and its maintenance role is not permanent, so this method can not deal with the basic problem, as long as the surface corrosion prevention, that is, the appearance of corrosion prevention treatment is the most widely used method.

Stainless steel screw surface corrosion prevention treatment refers to the use of various methods to apply a maintenance layer on the metal surface, its role is to isolate the metal and the corrosive environment, to inhibit the corrosion process, or reduce the corrosive medium and the metal surface contact, so as to avoid or reduce the purpose of corrosion.

Corrosion resistance, wear resistance, high hardness

Excellent corrosion resistance**: Both 316 and 316L contain 2-3% molybdenum, which gives them stronger corrosion resistance compared to the 304 series, especially in chloride environments like saltwater, making them suitable for high-corrosion settings.

Food-grade stainless steel 316 and 316L are austenitic stainless steels that are widely used in industries like food processing and pharmaceuticals, where high hygiene and corrosion resistance are critical. The primary difference between the two is their carbon content. Below are their advantages and applications:

### **Advantages of Stainless Steel 316 and 316L**:

1. **Excellent corrosion resistance**: Both 316 and 316L contain 2-3% molybdenum, which gives them stronger corrosion resistance compared to the 304 series, especially in chloride environments like saltwater, making them suitable for high-corrosion settings.

2. **Good high-temperature performance**: Stainless steel 316 offers better strength and oxidation resistance at high temperatures compared to the 304 series, making it suitable for high-temperature environments.

3. **Low carbon content (316L)**: 316L is the low-carbon version of 316, with a carbon content of less than 0.03%, reducing the risk of intergranular corrosion after welding. This makes 316L ideal for food and pharmaceutical equipment that requires extensive welding.

4. **Easy to clean**: The surface of 316 and 316L stainless steel is smooth and easy to clean, effectively preventing food residues, dirt, and microorganisms from adhering, meeting food safety standards.

5. **Non-magnetic**: In their annealed state, both are non-magnetic, which is beneficial for products requiring low magnetic properties.
