What is the difference between stainless steel screws and carbon steel screws.

First, the material is different.

Stainless steel material and carbon steel material is still significantly different: carbon steel mainly refers to the national performance depends on the carbon content of steel, and generally will not be added a large number of artificial alloying elements steel, sometimes also known as plain carbon steel and carbon steel, refers to the amount of carbon WC less than 2% of the carbon-carbon alloys, carbon steel carbon, generally also contains a small amount of silicon, manganese, sulfur, phosphorus. Stainless steel usually refers to a certain corrosion resistance alloy steel, its main chemical composition is chromium and nickel.

Second, the performance is different.

Carbon steel based on the carbon content is divided into low carbon steel, medium carbon steel, high carbon steel, its carbon content is different, the hardness is not the same; and stainless steel because it contains chromium and nickel, the most obvious performance is the atmospheric corrosion resistance, according to the organization of the steel, stainless steel can be divided into martensitic, ferrite type, austenitic, ferrite, austenitic, precipitation hardening stainless steel, in our daily lives! In our contact with more austenitic stainless steel (nickel stainless) and martensitic stainless steel ("stainless steel").

Third, the magnetic difference.

Carbon steel and galvanized steel is not much difference, stainless steel a . Generally not magnetic, but not absolutely, austenitic is not magnetic, but ferritic has, but also relatively weak.

In summary, stainless steel screws and carbon steel screws are different from the hardness, magnetism, rust resistance.

Carbon steel bolts are generally used in more conventional occasions, such as furniture, building materials, etc., and some special requirements of the industry must be stainless steel, especially for the high security requirements of the occasion, as well as some exposure to sunlight, high temperature, low temperature, corrosive high occasions.

Stainless steel bolts are not necessarily corrosion and rust, just that stainless steel bolts relative to iron bolts to carry corrosion and rust ability is strong. But stainless steel bolts in specific circumstances or rust.

Stainless steel bolts have good characteristics, a strong ability to carry corrosion, high temperature resistance, but also has a strong anti-rust properties. But in the harsh environment will still rust.

For example, stainless steel bolts in a very humid situation, every day sun and wind, wind and rain. Long time, more or less sure to rust a little. For example, and some acid and alkali chemicals contact, so that the chemical reaction. The result is corrosion and rust.
