The most used stainless steel screws today

Bolts, screws  are mechanical products are too familiar in human life, as well as widgets are used everyday in the family.

Why  stainless steel screws  are the first choice of many investors. Here are some characteristics of stainless steel fasteners bolts  virtual Kim  helps you reference.

Most of the screws used in the past were materials used in steel but during the time of use, the impact of chemicals or surrounding environment that rust, fast. Therefore, stainless steel screws (stainless steel) are used today to bring more efficiency. 

Advantages of stainless steel screws

As its name implies, this type of screw bolt is resistant to chemical erosion or electrochemical corrosion from the environment, not discolored as easily as conventional steel. 

Bolt stainless steel screws  are resistant to oxidation, they can withstand harsh conditions during use. For marine applications along with the high tolerance of stainless steel with salty and seawater, this stainless steel bolt is a natural choice. 
 
Stainless steel screws are used in many different environments.

+ Stainless steel bolt is resistant (antioxidant), high strength and heat resistance, hardness is standard, so it can work in extreme conditions for many years.

+ The color of shiny stainless steel screws brings aesthetics to the equipment.

For the maritime industry, the tolerance of stainless steel with salty and seawater makes this bolt type the first choice.

Classification of stainless steel screws

The most used screws in the market today are stainless steel bolts 201, 304, 316L, and 316, 410.

- Stainless steel bolt 201 is steel grade has good bearing capacity, due to the hardness of the material. The high aesthetics of the product thanks to the shiny surface, the price of products made of stainless steel 201 is reasonable. However, the disadvantage of the stainless steel material 201 is the limited chemical resistance to corrosion, so it should only use products made of stainless steel 201 in locations where the chemical corrosion is less, lip work field dry.

- Stainless steel bolt is a stainless steel material, which is hard material, so it is easy to drill into hard surfaces such as metal, which is the strength of this material. Use 410 stainless steel to produce stainless steel screws. 
Limited resistance to chemicals, so locations where chemical erosion large should not use 410 stainless steel.

- Screw in stainless steel 304 is a stainless steel, is the most commonly used material in the stainless steel screw industry. Stainless steel 304 is very good chemical resistance, so products made from stainless steel 304 can be used in areas where chemical corrosion. Of course, products made from stainless steel 304 will cost more than products made from 410 stainless steel.

- Stainless Steel Screw 316 is not popular because of the high price. The advantage of this material is the superior chemical abrasion resistance, which can be used in locations in direct contact with sea water, chemicals.
