  • What kind of stainless steel is not easy to rust?
    Jul 30, 2018

    The main factors affecting the corrosion of stainless steel are three points:

    1. alloy elements. Generally speaking, chromium content is not easy to rust in 10.5% steel. The higher the content of chromium nickel is, the better the corrosion resistance, for example, the content of 304 material nickel is 8-10%, the content of chromium is 18-20%, so the stainless steel will not rust in general condition.

    2. the smelting process of production enterprises will also affect the corrosion resistance of stainless steel. The large stainless steel plant with good smelting technology, advanced equipment and advanced technology can guarantee the control of the alloy elements, the removal of impurities and the control of the cooling temperature of the steel billet, so the quality of the products is stable and reliable, the internal quality is good, and it is not easy to rust. Conversely, some small steel plants are backward in equipment and backward in technology. Impurities can not be removed during smelting, and the products produced will inevitably rust.

    3. external environment, climate, dry and well ventilated environment is not easy to rust. And the air humidity is large, continuous rainy weather, or air containing acid and alkali environment is easy to rust. 304 stainless steel, if the surrounding environment is too bad, it will rust.
