The main factors affecting the corrosion of stainless steel plate

There are three main factors that affect the corrosion of stainless steel plate:

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

2, the smelting process of the production enterprise Jinzhe will also affect the corrosion resistance of stainless steel. Smelting technology is good, advanced equipment, advanced technology, large stainless steel plant both in the control of alloying elements, the removal of impurities, billet cooling temperature control can be guaranteed, so the product quality is stable and reliable, good intrinsic quality, not easy to rust. On the contrary, some small steel plant equipment backward, backward technology, smelting process, impurities can not be removed, the production of products will inevitably rust.

3, the external environment, the climate is dry and well ventilated environment is not easy to rust. The air humidity, continuous rainy weather, or air containing acidity and alkalinity of the environment areas are prone to rust. Sanyou 304 stainless steel plate, if the surrounding environment is too poor is also rusty.
