What is stainless steel?
Stainless Steel (Stainless Steel) is the abbreviation of stainless acid-resistant steel, resistant to air, steam, water and other weak corrosive media or stainless steel; The steel that is resistant to chemical corrosion media (acid, alkali, salt and other chemical etching) is called acid-resistant steel.
Due to the difference in the chemical composition of the two, their corrosion resistance is different, ordinary stainless steel is generally not resistant to chemical medium corrosion, and acid-resistant steel is generally stainless. The term "stainless steel" does not simply refer to one kind of stainless steel, but means more than one hundred kinds of industrial stainless steel, each stainless steel developed has good performance in its specific application field. The key to success is first to understand the purpose and then to determine the correct steel grade. There are usually only six types of steel related to the application field of building construction. They all contain 17-22% chromium, and the better grades also contain nickel. The addition of molybdenum can further improve the corrosion of the atmosphere, especially the corrosion resistance of the atmosphere containing chloride.
Stainless steel refers to the steel that is resistant to weak corrosive media such as air, steam, water and chemical etching media such as acid, alkali, salt, also known as stainless acid-resistant steel. In practical applications, the steel that is resistant to the corrosion of weak corrosive media is often called stainless steel, and the steel that is resistant to the corrosion of chemical media is called acid-resistant steel. Due to the difference in the chemical composition of the two, the former is not necessarily resistant to chemical medium corrosion, while the latter is generally stainless. The corrosion resistance of stainless steel depends on the alloying elements contained in the steel.
Chemical composition of stainless steel
The main component of stainless steel is chromium, its chromium content should be between 15% and 30%, the higher the chromium content, the better the corrosion resistance, toughness and weldability of stainless steel.
What are the common stainless steel
Model 301- Good ductility for molding products. It can also be quickly hardened by machining. Good weldability. The wear resistance and fatigue strength are better than 304 stainless steel.
Model 302- corrosion resistance is the same as 304, and the strength is better because the carbon content is relatively higher.
Model 303- by adding a small amount of sulfur and phosphorus to make it easier to cut than 304.
Model 304- universal model; 18/8 stainless steel. The GB brand is 0Cr18Ni9.
Model 309- has better temperature resistance than 304.
Model 316- After 304, the second most widely used steel grade, mainly used in the food industry and surgical equipment, adding molybdenum element to make it obtain a special structure resistant to corrosion. Because it has better resistance to chloride corrosion than 304, it is also used as "Marine steel". SS316 is commonly used in nuclear fuel recovery units. Grade 18/10 stainless steel is also usually suitable for this application level.
Model 321- Similar in performance to 304 except that the addition of titanium reduces the risk of corrosion in the material weld.
400 Series - ferritic and martensitic stainless steel
Model 408- Good heat resistance, weak corrosion resistance, 11% Cr, 8% Ni.
Model 409- the cheapest model (Anglo-American), usually used as an automobile exhaust pipe, is a ferritic stainless steel (chromium steel).
Model 410-martensite (high strength chromium steel), good wear resistance, poor corrosion resistance.
Model 416- The addition of sulfur improves the processing properties of the material.
Model 420- "Tool grade" martensitic steel, similar to Brinell high chromium steel, the earliest stainless steel. Also used in surgical knives, can be made very bright.
Model 430- ferritic stainless steel, for decorative purposes, e.g. for automotive accessories. Good formability, but poor temperature resistance and corrosion resistance.
Model 440- high strength cutting tool steel, slightly higher carbon content, after appropriate heat treatment can obtain high yield strength, hardness can reach 58HRC, is one of the hardest stainless steel. The most common example is the "razor blade". There are three common models: 440A, 440B, 440C, and 440F (easy to process).
500 Series - Heat-resistant chrome alloy steel.
600 Series - Martensitic precipitation hardening stainless steel.
Model 630- the most commonly used precipitation hardened stainless steel model, usually called 17-4; 17%Cr, 4%Ni. Chromium 18-20.

Frequently asked Questions about stainless steel
Q: What is stainless steel is made of?
The raw material of stainless steel is ordinary carbon steel, on the basis of which other chemical elements are added, such as the addition of chromium, the content of which is more than 12%, through the production of a stainless steel material. Its main feature is that it is not easy to rust, it is not easy to corrode under the action of the atmosphere, and it maintains the luster of the metal.
Q: What are the 3 metals in stainless steel?
Q: Stainless steel food grade 316 or 304 good?
Q: Why is steel called stainless?
Q: How is stainless steel formed?
Q: Is stainless steel magnetic?
Q: What is the reason why stainless steel has good corrosion resistance?
2. ordinary stainless steel contains chromium, nickel elements, of course, this is also an "alloy", chemical properties are more stable, weak acid, alkali, salt can not take it;
3.slightly better stainless steel added titanium, molybdenum, silicon, nitrogen, etc., it can withstand more excellent corrosive media or environment. Note: Nickel (Ni) is the main valuable ingredient in most of the stainless steel materials, and its price directly determines the price of the stainless steel industry.
Q: Is stainless steel resistant to acid and alkali corrosion?
Q: Does methanol corrode stainless iron?
Q: Is ferritic stainless steel resistant to hydrogen sulfide corrosion?
Therefore, ferritic stainless steel can be used in H2S environment, but those with high hardness and greater than HB200 are basically high carbon content and cannot be used in H2S environment; It's better to have stabilizing elements, like Nb,Ti; The state of supply should preferably be in solid solution.
Q: What is ferritic stainless steel?
Q: Is austenitic steel magnetic?
Austenitic type: such as 304, 321, 316, 310, etc. 304 stainless steel after cold processing, the structure will also be transformed to martensite, the greater the deformation of cold processing, the more martensite transformation, the greater the magnetic steel.
Austenitic stainless steel is a common stainless steel (18-8 steel), such as many tableware in the kitchen are made of austenitic stainless steel. Austenitic stainless steel, as the name suggests its organization is austenite, it is not magnetic, no hardening.
Austenitic stainless steel in the oxidizing environment is very strong corrosion resistance, the so-called oxidizing environment can be simply understood as a more oxygen-containing environment, austenitic stainless steel toughness is good, easy to process molding, so it is very widely used.
Q: Is martensitic stainless steel magnetic?
Q: What are the characteristics of martensitic stainless steel?
Martensitic stainless steel is a kind of stainless steel that can adjust its properties by heat treatment (quenching, tempering), in popular terms, is a kind of hardened stainless steel. This characteristic determines that this type of steel must have two basic conditions: First, there must be an austenitic phase region in the equilibrium phase diagram, in the temperature range of the region for a long time heating, so that the carbide solid solution into the steel, quenching to form martensite, that is, the chemical composition must be controlled in the γ or γ+α phase region, the second is to make the alloy to form corrosion resistance and oxidation passivated film, chromium content must be more than 10.5%. According to the difference of alloying elements, it can be divided into martensitic chromium stainless steel and martensitic chromium nickel stainless steel.
The main alloying elements of martensitic chromium stainless steel are iron, chromium and carbon. Figure 1-4 is Fe-Cr phase diagram Fe-rich part, such as Cr greater than 13%, there is no γ phase, such alloys for single-phase ferritic alloy, in any heat treatment system can not produce martensite, so must be added to the Fe-Cr binary alloy austenitic forming elements, to expand, C, N are effective elements, The addition of C and N elements allows a higher chromium content in the alloy. In martensitic chromium stainless steel, in addition to chromium, C is the other most important essential element, in fact, Martensitic chromium stainless steel is a class of iron, chromium, carbon ternary alloy. Of course, there are other elements with which the general organization can be determined according to the Schaeffler diagram.
Martensitic stainless steel is mainly low carbon or high carbon steel with chromium content in the range of 12%-18%.
