Classification methods of stainless steel materials
There are many classification methods of stainless steel materials, the most common ones are the following, among which the classification according to metallographic structure is the most common. universal.
Classified by chemical composition
Basically, it can be divided into chromium series stainless steel (such as ferrite series, martensitic series) and chromium-nickel series stainless steel (such as austenite series, abnormal series, precipitation hardening series) ) two major systems.
According to the classification of metallographic structure
It can be divided into austenitic stainless steel, ferritic stainless steel, martensitic stainless steel, duplex stainless steel and precipitation hardening stainless steel.
According to the type of corrosion resistance
It can be divided into stress corrosion resistant stainless steel, pitting corrosion resistant stainless steel, intergranular corrosion resistant stainless steel, etc.
Classified by functional characteristics
Can be divided into easy-cutting stainless steel
, non-magnetic stainless steel, low-temperature stainless steel, and high-strength stainless steel.
At present, there are nearly all kinds of stainless steel that have been incorporated into various standards in the world, and with the advancement of science and technology and the development of industry and agriculture, new stainless steel grades are constantly increasing. For a known grade of stainless steel, its chromium equivalent [] and nickel equivalent [] can be calculated based on its chemical composition, and then the stainless steel structure diagram can be used to roughly estimate the structure and properties of the steel type.
Made of stainless steel, it has a brightness close to that of a mirror and has a tough and cold touch. It is a relatively avant-garde decorative material and conforms to the cool aesthetic of the metal age. Stainless steel materials are usually divided into ferritic stainless steel according to the matrix structure. Contains chromium ~3. Its corrosion resistance, toughness and weldability increase with the increase of chromium content, and its chloride stress corrosion resistance is better than other types of stainless steel. , austenitic stainless steel. It contains more than 60% chromium, and also contains about 10% nickel and a small amount of molybdenum, titanium, nitrogen and other elements. It has good comprehensive performance and can withstand corrosion from various media. , Austenitic-ferritic duplex stainless steel. It has the advantages of both austenitic and ferritic stainless steel and has superplasticity. , martensitic stainless steel. High strength, but poor plasticity and weldability.
