Generally speaking, carbon steel screws do not have steel with alloy elements added. Stainless steel screws are mainly added steel with high alloy content for anti-rust, mainly to prevent rust. Stainless steel screws are more expensive than carbon steel screws. These two screws are used for both purposes. It is not the same, it cannot be compared to good or bad. Carbon steel screws are stronger than stainless steel screws and are easier to rust. Carbon steel has poor corrosion resistance and will rust to death after a long time, while stainless steel screws are specially made to prevent rust. of.

When choosing stainless steel screws, it mainly depends on the mechanical strength requirements of stainless steel screws and the corrosion of work. The requirements on the heat resistance and high temperature strength performance of materials at working temperature and the production process are very demanding on the processing performance of materials. High, there is price, weight, heat resistance, corrosion and so on.
