PRODUCT SHOW
APPLICATION
321 stainless steel contains Ti content as a stabilizing element, but it is also a heat-strength steel type, which is much better than 316L in terms of high temperature. 321 stainless steel has good abrasion resistance in organic acids and inorganic acids of different concentrations and temperatures, especially in oxidizing media, and is used to manufacture wear-resistant acid containers and linings and pipelines for wear-resistant equipment.
321 stainless steel is a Ni-Cr-Ti austenitic stainless steel. Its performance is very similar to that of 304, but due to the addition of metallic titanium, it has better resistance to grain boundary corrosion and high temperature strength. The addition of metallic titanium effectively controls the formation of chromium carbide.
321 stainless steel has excellent high-temperature stress rupture (Stress Rupture) performance and high-temperature creep resistance (Creep Resistance) stress mechanical properties that are better than 304 stainless steel. Suitable for welding components used at high temperatures.

About STAINLESS STEEL
OVERVIEW AND APPLICATION OF STAINLESS STEEL
Stainless Steel is a kind of steel with excellent corrosion resistance. It can resist the erosion of weak corrosive media such as air, steam, water, and chemical substances such as acid, alkali, and salt. Therefore, it is also called acid-resistant steel. According to the type of corrosion-resistant medium, steel resistant to weak corrosive media is usually called stainless steel, while steel resistant to chemical media is called acid-resistant steel. The two are different in chemical composition, so stainless steel may not have the ability to resist chemical media, while acid-resistant steel is usually stainless.
The corrosion resistance of stainless steel mainly depends on the content and type of its alloying elements.
TYPES OF STAINLESS STEEL:
Ferritic stainless steel: contains 12% to 30% chromium, has good corrosion resistance and weldability, and is suitable for low-stress acid-resistant structures. Widely used in high-temperature environments such as food industry and chemical plant equipment.
Austenitic stainless steel: contains more than 18% chromium and about 8% nickel. It has good plasticity, toughness, weldability and corrosion resistance. It is suitable for a wide range of industrial and construction equipment, especially in acid-resistant containers and pipelines.
Austenite-ferrite duplex stainless steel: It has the characteristics of both austenite and ferrite stainless steel, with superplasticity, high strength and corrosion resistance, and is widely used in occasions that require resistance to chloride stress corrosion.
Martensitic stainless steel: High strength, high hardness, wear resistance, but poor corrosion resistance, often used for parts requiring higher mechanical properties, such as springs, turbine blades, etc.
ADVANTAGES OF STAINLESS STEEL:
Corrosion resistance: Stainless steel can effectively prevent corrosion, pitting, rust and wear, and ensure the long-term stability of structural components.
Mechanical properties: In structural applications, stainless steel has high strength, good ductility, easy processing, and is suitable for complex construction and industrial needs.
Long-term and aesthetics: Due to its excellent corrosion resistance, the appearance of the building can remain intact for a long time, and different surface effects (such as polishing, brushing, etc.) can be provided according to design requirements.
TYPICAL USES OF STAINLESS STEEL:
Construction industry: used for curtain walls, roofs, side walls and other structures, and different grades of stainless steel (such as 304, 316, etc.) are selected in different environments.
Industrial facilities: equipment and pipelines used in highly corrosive environments, such as chemical plants, food factories, etc.
Home and daily use: such as kitchen equipment, bathroom supplies, etc., are widely used in modern home life due to their durability and easy-to-clean characteristics.
Surface state of stainless steel:
In order to meet different aesthetic needs, the surface of stainless steel can be processed by polishing, embossing, electroplating, etc. to form a bright, matte, colored or patterned effect, which is easy to clean and maintain.
FUTURE PROSPECTS:
With the continuous improvement of production processes and technologies, the application of stainless steel in the construction industry will be further expanded, and it will continue to be one of the first choices for building materials. Its excellent performance and aesthetic effects make it popular worldwide.
