Storage tanks play a critical role in industrial operations such as chemical processing, pharmaceuticals, food manufacturing, oil refineries, water treatment plants, and many other sectors. Among the most commonly used materials are MS storage tanks (Mild Steel) and SS storage tanks (Stainless Steel).
Choosing between an MS tank vs SS tank is not just about price—it involves factors like corrosion resistance, hygiene standards, durability, chemical compatibility, and long-term maintenance cost. This detailed guide explains the difference between MS and SS storage tank, their advantages, disadvantages, industrial applications, and how to select the best storage tank material for industrial use.
An MS storage tank, also known as a mild steel storage tank, is manufactured using low-carbon steel. Mild steel is known for its strength, ease of fabrication, and cost-effectiveness, making it one of the most widely used materials in industrial storage solutions.
Industrial MS storage tanks are commonly used for storing water, oils, fuels, non-corrosive chemicals, and raw materials. Due to lower material cost and flexible fabrication, MS tanks are preferred where budget constraints exist and corrosion risk is manageable through coatings or linings.
An SS storage tank or stainless steel storage tank is made from corrosion-resistant alloys containing chromium and nickel. The most common grades used are SS 304 storage tank and SS 316 storage tank.
Industrial SS storage tanks are ideal for applications requiring high hygiene, chemical resistance, and long service life. These tanks are widely used in pharmaceutical, food & beverage, biotechnology, cosmetics, and corrosive chemical industries.
| Comparison Factor | MS Storage Tank | SS Storage Tank |
|---|---|---|
| Material | Mild Steel (Low Carbon Steel) | Stainless Steel (SS 304 / SS 316) |
| Corrosion Resistance | Low without coating; needs painting or lining | Excellent natural corrosion resistance |
| Fabrication | Easy MS tank fabrication | Requires skilled SS tank fabrication |
| Maintenance | Higher due to corrosion risk | Low maintenance |
| Hygiene | Not suitable for food & pharma | Ideal for hygienic industries |
| Cost | Low MS storage tank price | Higher SS storage tank price |
| Durability | Moderate | High and long-lasting |
One of the most common decision-making factors is cost. MS storage tank price is significantly lower than SS tanks, making MS tanks suitable for large-capacity storage where budget matters more than corrosion resistance.
On the other hand, SS storage tank price is higher due to expensive raw materials and precision fabrication. However, SS tanks offer lower lifecycle cost because of minimal maintenance, longer life, and zero coating requirements.
MS tank corrosion resistance is inherently low. Mild steel reacts with moisture and chemicals, leading to rust formation. To improve performance, MS tanks require epoxy coating, rubber lining, or galvanization.
In contrast, SS tank corrosion resistance is naturally high due to chromium oxide formation on the surface. Grades like SS 316 storage tank offer excellent resistance against chlorides, acids, and aggressive chemicals.
Knowing when to use MS storage tank helps avoid unnecessary cost escalation. MS tanks are ideal where chemical aggressiveness is low and storage conditions are controlled.
Advantages: Low cost, easy fabrication, customizable thickness, widely available MS tank supplier India.
Disadvantages: Poor corrosion resistance, higher maintenance, limited hygiene use.
Understanding when to use SS storage tank is critical for regulated and hygiene-sensitive industries.
Advantages: Excellent corrosion resistance, hygienic, long service life, minimal maintenance.
Disadvantages: Higher initial investment, complex fabrication.
There is no universal answer to which is better MS or SS storage tank. The decision depends on application, budget, chemical compatibility, hygiene needs, and lifecycle expectations.
This industrial storage tank buying guide helps industries choose the right material:
The difference between mild steel and stainless steel storage tanks lies in cost, corrosion resistance, hygiene, and industrial suitability. MS storage tanks offer economical solutions for general industrial storage, while SS storage tanks deliver premium performance for sensitive and corrosive applications.
By understanding MS vs SS tank comparison, industries can make informed decisions that balance performance, safety, and cost efficiency—ensuring long-term operational success.
