The metal that has the "incorruptible body of King Kong" is stainless steel.
Stainless steel is closely related to people's lives. Many of the kitchenware we use is made of stainless steel. itIt is hard and resistant to high temperatures and corrosion。Therefore, it is widely used in industrial materials.
Stainless steel
As defined in GB T20878-2007, it is defined as:Stainless steel and corrosion resistance are the main characteristicsand a chromium content of at least 105%, and the maximum carbon content does not exceed 12% steel.
It is the abbreviation of stainless acid-resistant steel
Stainless steel
Resistant to weak corrosive media such as air, steam, water, or steel grades with stainless steel.
Acid-resistant steel
A steel grade that is resistant to chemical corrosion by chemical agents (acids, alkalis, salts, etc.).
The main component of stainless steel
It's iron and chromium, and if you add other elements, it will have more performance. According to the different types and proportions of elements it contains, stainless steel is divided into more than 100 types.
How to use stainless steel utensils correctly?
1. Do not use strong alkali, strong acid or strong oxidizing chemicals (such as soda bleaching powder, hypochlorous acid, etc.) to wash stainless steel.
The reason is that these substances are strong electrolytes, and after electrochemical reaction with stainless steel utensils, the trace elements of stainless steel will be dissolved.
2. Do not use stainless steel utensils to hold salt, soy sauce, vinegar and other items for a long time.
These foods contain many electrolytes, and if left for a long time, stainless steel, like other metals, will electrochemically react with these electrolytes to dissolve toxic metal elements.
