Basic types of stainless steels
Technical Characteristics
Stainless steels are iron-based alloys containing at least 12% chromium. Chromium forms a surface oxide film that protects the metal. This corrosion-resistant film makes the alloy stainless. If the metal loses its protective coating, corrosion may appear in that place. But, as a rule, the protective film can be easily restored by oxygen. The major types of stainless steels are divided into three groups, depending on their structure.
Austenitic Steel
Austenitic steels contain 16 to 25% chromium and 6 to 14% nickel. They can be alloyed with 2 to 6% molybdenum and can also include other elements. These steels are widely used in power engineering, mechanical engineering, industrial chemistry, food industry, household and medicine. About 60-70% of the world steel consumption is in the austenitic grades.
Ferritic steel
Ferritic steels are also called chromium steels. These steels contain from 12 to 20% Cr. Some grades are alloyed with small amounts of molybdenum and titanium. It is worth noting that the corrosion resistance, heat resistance and other parameters are slightly lower than those of the austenitic steels. But the cost of metals of the second group is also lower than that of the first group.
Martensitic steels
These are martensitic stainless steels, which are used only when maximum strength and hardness is required of the metal.
