Product Description:

Stainless steel 304 is one of the most widely used grades of stainless steel, known for its excellent corrosion resistance, good mechanical properties, and ease of fabrication. It belongs to the austenitic family of stainless steels, which are non-magnetic and characterized by high toughness and good weldability. Due to these attributes, 304 stainless steel is used across various industries, including food processing, chemical processing, construction, and household appliances. This article will delve into the key characteristics of 304 stainless steel, including its chemical composition, physical properties, mechanical properties, and corrosion resistance.
 
1. Chemical Composition
Stainless steel 304 consists primarily of iron, with a significant percentage of chromium and nickel. The typical chemical composition of 304 stainless steel is as follows:
Chromium (Cr): 18–20%
Nickel (Ni): 8–10.5%
Manganese (Mn): 2%
Silicon (Si): 1%
Carbon (C): 0.08% max
Phosphorus (P): 0.045% max
Sulfur (S): 0.03% max
Iron (Fe): balance
The high chromium content provides the stainless steel with its resistance to corrosion, while nickel enhances its formability and weldability. The balance of iron forms the base material, providing the necessary strength and structure to the alloy.
 
2. Physical Properties
The physical properties of 304 stainless steel make it suitable for a wide range of applications. Some of its key physical characteristics include:
Density: 7.93 g/cm³
Melting Point: 1400°C (2552°F)
Thermal Conductivity: 16 W/m·K at 100°C
Electrical Resistivity: 0.72 µΩ·cm at 20°C
Magnetic Properties: 304 stainless steel is non-magnetic in the annealed condition, which is a key feature for applications where magnetic properties must be minimized, such as in certain medical and electronic devices.
 
Due to its relatively low density, 304 stainless steel is lightweight compared to many other metals, which is advantageous for applications in sectors like aerospace and automotive industries.
 
3. Mechanical Properties
304 stainless steel exhibits excellent mechanical properties, particularly in terms of strength and ductility. The alloy maintains its mechanical strength at both high and low temperatures, which makes it suitable for use in a variety of environments. The following are key mechanical properties:
Tensile Strength: 520–750 MPa
Yield Strength: 215 MPa (min)
Elongation: 40% (in 50 mm gauge length)
Hardness: Brinell hardness ~170 HB, Rockwell B ~90 HRB
Modulus of Elasticity: 193 GPa
304 stainless steel maintains its strength even at high temperatures, up to around 870°C (1600°F) in intermittent service, and up to 925°C (1700°F) in continuous service. This makes it suitable for applications that involve high heat, such as heat exchangers, boilers, and pressure vessels.
 
4. Corrosion Resistance
One of the most defining features of 304 stainless steel is its exceptional corrosion resistance. The chromium content in the alloy forms a passive oxide layer on the surface that protects it from rust and other forms of corrosion. The presence of nickel further enhances this corrosion resistance, particularly in reducing environments. The corrosion resistance of 304 stainless steel makes it ideal for use in industries such as food processing, pharmaceuticals, and marine environments. Specific aspects of its corrosion resistance include:
Resistance to Rust: 304 stainless steel resists rust and staining in most environments. It is particularly resistant to oxidation and scaling at elevated temperatures.
Pitting Resistance: In environments containing chlorides (e.g., seawater), 304 stainless steel provides reasonable resistance to pitting corrosion. However, it may not be suitable for highly aggressive chloride-rich environments, such as those found in seawater, where alloys like 316 may be more appropriate.
Stress Corrosion Cracking (SCC): While 304 stainless steel has good resistance to SCC in most environments, it is susceptible to SCC in high-temperature water or in environments containing chlorides at elevated temperatures.
Intergranular Corrosion: 304 stainless steel can be susceptible to intergranular corrosion when exposed to temperatures in the range of 425–850°C, particularly if the material is improperly heat-treated. This issue can be avoided by using stabilized grades like 304L or 321, which have lower carbon content.
 
5. Formability and Weldability
304 stainless steel is highly formable and can be easily fabricated into various shapes and sizes. It can be rolled, drawn, and formed into different types of products, such as sheets, coils, plates, and pipes. Its excellent weldability allows it to be welded using most standard welding techniques, including TIG (Tungsten Inert Gas), MIG (Metal Inert Gas), and arc welding.
 
When welding 304 stainless steel, care must be taken to avoid overheating, which can lead to sensitization (a form of intergranular corrosion). Using proper welding procedures, such as post-weld heat treatment, can mitigate this issue.
 
6. Applications of Stainless Steel 304
Given its unique combination of strength, corrosion resistance, and formability, 304 stainless steel is used in a wide range of applications across various industries:
Food and Beverage Industry: Due to its resistance to corrosion and ease of cleaning, 304 stainless steel is commonly used in the production of food processing equipment, such as tanks, pipes, and machinery.
Chemical and Pharmaceutical Industries: Its resistance to corrosion from a wide range of chemicals makes 304 stainless steel an ideal choice for processing equipment, including reactors, vessels, and heat exchangers.
Construction: Stainless steel 304 is often used in architectural applications, such as structural supports, roofing materials, and decorative items, where both appearance and durability are important.
Household Appliances: 304 stainless steel is widely used in kitchen appliances, including refrigerators, dishwashers, sinks, and cooktops, due to its ease of cleaning and resistance to stains.
Marine Applications: While 304 stainless steel is resistant to rust and corrosion in marine environments, it is sometimes replaced by the more corrosion-resistant 316 stainless steel when subjected to continuous exposure to seawater or chloride-rich conditions.

Stainless steel 304 is an extremely versatile and widely used material due to its excellent combination of mechanical properties, corrosion resistance, formability, and weldability. Whether for household applications, industrial machinery, or marine environments, its unique characteristics make it one of the most reliable and durable materials available. However, depending on the specific environmental conditions (such as exposure to extreme temperatures or aggressive chemicals), other stainless steel grades like 316 or 321 may offer enhanced performance for specialized applications.

 

Applications

Sandblasting is a process for surface treatment of workpieces. Adopting compressed air as the power, in order to form a high-speed jet beam will spray material (copper ore, quartz sand, emery, iron sand, sea sand) high-speed jet to the surface of the workpiece to be processed, so that the appearance or shape of the surface of the workpiece changes. Due to the impact and cutting effect of the abrasive on the surface of the workpiece, the surface of the workpiece obtains a certain degree of cleanliness and different roughness, so that the mechanical properties of the surface of the workpiece can be improved, thus improving the fatigue resistance of the workpiece, increasing the adhesion between it and the coating, prolonging the durability of the coating film, and also conducive to the levelling of the coating and decoration.

 

Cadmium plating is also prone to ‘cadmium brittle’ phenomenon, usually at higher temperatures, and at the same time the existence of certain stress conditions, can make steel and titanium alloys produce cadmium brittle. As cadmium plating layer in 232 ℃ above can be leached into the steel parts of the matrix, can cause the so-called ‘cadmium brittle’ phenomenon, so the use of temperature should not exceed 232 ℃.
Cadmium-plated layer can be welded, the plating can reduce the oxidation of copper-plated electrical contacts, but also does not increase the contact resistance. Cadmium-plated layer is usually used in steel fasteners, piping and other stressed parts, aluminium and aluminium alloy parts, magnesium alloy parts, and rubber contact with the steel and copper parts. Especially some elastic parts, threaded parts, standard parts and aerospace, shipbuilding, electronics and military products are used to use cadmium plating. But cadmium vapour and its soluble salts are highly toxic and seriously pollute the environment. Therefore, the application of cadmium plating layer is subject to strict limitations, has been rarely used, most of the zinc plating layer and zinc alloy layer to replace the cadmium plating layer.
