Stainless steel bolts refer to bolts made of stainless steel, including stainless steel SUS201 bolts, stainless steel SUS304 bolts, stainless steel SUS316 bolts, and stainless steel SUS316L bolts. The performance grades of stainless steel bolts, studs and studs are divided into 10 grades: from 3.6 to 12.9. The number before the decimal point represents 1/100 of the ultimate tensile strength of the material, and the number after the decimal point represents 10 times the ratio of the yield limit of the material to the ultimate tensile strength.

So the difference between stainless steel bolts and carbon steel bolts, in the final analysis, is the difference between stainless steel and carbon steel. This question has been introduced many times by the editor! Here, the editor will introduce the difference between stainless steel bolts and carbon steel bolts in general.
The difference between stainless steel bolts and carbon steel bolts is that the cost of stainless steel is higher than that of carbon steel, and it is more durable than carbon steel, not easy to rust, more resistant to high and low temperature and corrosion, and has more advantages. The cost of carbon steel is lower. Although it is not as good as stainless steel in some places, it has the advantages of easy smelting and good processing technology.
After understanding the difference between stainless steel bolts and carbon steel bolts, it is clearer about their selection!
Carbon steel bolts are generally used in more conventional occasions, such as furniture, building materials, etc., while some industries with special requirements must use stainless steel, especially in occasions with high safety requirements, and some exposure, high temperature, low temperature, and high corrosion occasions.
Stainless steel bolts are not necessarily free from corrosion and rust, but stainless steel bolts are more resistant to corrosion and rust than iron bolts. However, stainless steel bolts will still rust under certain circumstances. So under what conditions are stainless steel bolts prone to rust? What are the causes of rust?
Stainless steel bolts have better characteristics, strong corrosion resistance, high temperature resistance, and strong anti-rust performance. But it will still rust in harsh environments. For example, stainless steel bolts are exposed to the sun and wind every day in very humid conditions. After a long time, it will definitely rust a little. For example, in contact with some acid-base chemicals to cause a chemical reaction. cause corrosion and rust. There are also stainless steel bolts that are not good, such as stainless steel SUS201 bolts used in seawater. Due to long-term immersion, SUS201 stainless steel bolts are not suitable for use in seawater with strong saltiness. cause corrosion and rust. For use on seawater products, it is generally recommended to use stainless steel SUS316 bolts, because 316 stainless steel bolts have better corrosion resistance and other performance.
From the above, it can be concluded that stainless steel bolts will still corrode and rust under certain circumstances. Therefore, this requires the rational use of stainless steel bolts. Stainless steel bolts of different materials are used in different situations. And in different occasions, when using stainless steel bolts, special attention is also required, and some details need to be considered. Try to control the corrosion and rust of stainless steel bolts.
The above is the difference between stainless steel bolts and carbon steel bolts, and how to choose the two. Is it clear to everyone now?
