316L/304 Vegetable Fermentation Tank

Henan Beibang Steel is a professional manufacturer of 316L/304 vegetable fermentation tanks.
Both 316L and 304 are austenitic stainless steels, sharing common advantages such as non-magnetism, ease of welding, high toughness, and ease of processing and forming, making them the preferred materials for the food industry.
a. 304 Stainless Steel —— An Economical and Reliable General Choice
Core Composition: Contains 18% chromium and 8% nickel (commonly known as 18-8 stainless steel).
Recommended Reasons:
Acid Resistance: Exhibits good corrosion resistance to organic acids (such as lactic acid and acetic acid), fully meeting the working condition requirements of most vegetable fermentations.
Economy: Offers excellent cost performance and is the most widely used steel in the food industry.
Suitable Scenarios: Very suitable for vegetable fermentation products with short fermentation cycles, not extremely high acidity, and conventional sodium chloride concentrations (usually recommended below 5%).
b. 316L Stainless Steel —— A Professional Choice with Enhanced Corrosion Resistance
Core Composition: Based on 304, 2-3% molybdenum (Mo) is added.
Recommended Reasons:
Key Advantage —— Resistance to Chloride Ion Corrosion: The addition of molybdenum greatly enhances the steels ability to resist pitting and crevice corrosion, especially effectively combating the erosion of chloride ions.
Superior Acid Resistance: Corrosion resistance to various acidic media (including sulfuric acid and phosphoric acid) is better than 304.
The Meaning of the "L" Version: Ultra-low carbon content minimizes the risk of "intergranular corrosion" during welding and processing, ensuring the structural stability and corrosion resistance of welded areas.
