What Is 904L Stainless Steel: Properties and Applications

Views: 517 Author: Site Editor Publish Time: Origin: Site

904L stainless steel is a type of super austenitic stainless steel, extensively used in the chemical industry, petroleum industry, paper industry, pharmaceutical industry, and food and beverage production. Its excellent performance and broad application scenarios are attributed to its unique chemical element content and distinctive material properties.


Elemental Composition of 904L Stainless Steel

The primary elements in 904L stainless steel are:

Chromium (Cr): 19.0% - 23.0%
Nickel (Ni): 23.0% - 28.0%
Copper (Cu): 1.0% - 2.0%
Molybdenum (Mo): 4.0% - 5.0%
Iron (Fe): Balance
Carbon (C): ≤0.02%
Manganese (Mn): ≤2.0%
Silicon (Si): ≤1.0%
Phosphorus (P): ≤0.045%
Sulfur (S): ≤0.035%
Boron (B): 0.005% - 0.05%

The high content of chromium and nickel gives 904L stainless steel its excellent corrosion resistance. The addition of molybdenum and copper further enhances its corrosion resistance in strong acid environments.

Mechanical Properties

The mechanical properties of 904L stainless steel depend on its composition and heat treatment. In its untreated state, 904L stainless steel has lower strength but higher plasticity and toughness. After heat treatment, its strength significantly increases, but its plasticity and toughness decrease.

Typical mechanical properties are:

Tensile Strength: 900 MPa
Yield Strength: 650 MPa
Elongation: 20%
Reduction of Area: 50%


904L Stainless Steel Application

Due to its excellent corrosion resistance, 904L stainless steel is widely used in:

Chemical industry: Resistant to strong acids and bases.
Petroleum and natural gas industry: Superior corrosion resistance in sulfur-containing environments.
Paper industry: Resistant to corrosion from sulfates and chlorides.
Pharmaceutical industry: Resistant to various corrosive chemicals.
Food and beverage production: Combines corrosion resistance with good mechanical and welding properties


Advantages of 904L Stainless Steel

1. Superior corrosion resistance.
2. Excellent welding properties.
3. Outstanding mechanical properties.
4. Good impact resistance at low temperatures.
5. High wear resistance.
6. Stability at high temperatures, operable between 425℃-1300℃.

In conclusion, the unique elemental composition of 904L stainless steel grants it superior corrosion resistance, welding, and mechanical properties, as well as wear resistance and high-temperature stability. Its unique properties make it a popular choice in various industries. However, its cost is higher compared to other stainless steel materials, so considerations of practicality and budget are essential.
