What kind of Stainless Steel hardware products are not easy to rust?


1. The content of alloying elements.

Generally speaking, the chromium content is 10.5%, and steel is not easy to rust. The higher the content of chromium nickel, the better the corrosion resistance, such as 304 material nickel content in 8-10%, chromium content up to 18-20%, such stainless steel in general will not rust.

2. The smelting process of the production enterprise will also affect the corrosion resistance of stainless steel.

Large stainless steel plants with good smelting technology, advanced equipment and advanced technology can be guaranteed whether it is in the control of alloying elements, the removal of impurities, and the control of billet cooling temperature, so the product quality is stable and reliable, the internal quality is good, and it is not easy to rust. On the contrary, some small steel mills have backward equipment, backward technology, impurities cannot be removed during the smelting process, and the products produced will inevitably rust.

3. External environment, dry and ventilated environment, not easy to rust.

The air humidity is high, continuous rainy weather, or environmental areas with high pH in the air are easy to rust. 304 stainless steel, if the surrounding environment is too poor, it will also rust.
