How does material selection affect the investment cost of process tanks?
Material selection is an important factor affecting the investment cost of industrial process tanks.
Stainless steel 304 is widely used in many hygienic applications and is in many cases a more cost-effective option in less corrosive environments.
For higher corrosion resistance requirements, such as aggressive chemicals or chloride-containing liquids, acid-resistant 316/316L is often used. This can mean a higher cost per liter depending on the material’s properties and design requirements.
Factors such as weld design, surface finish and possible testing can also affect the overall cost picture.
Processöverskott offers tanks in stainless steel 304 and acid-proof 316/316L in various designs. Available information on materials and construction can be used as a basis for choosing a solution based on current process requirements and budget.
Function and structure
The investment cost is affected by the design and operation of the tank:
- Choice of stainless steel (304, 316, 316L, duplex)
- Plate thickness and reinforcements
- Pressure class (atmospheric or pressurized)
- Integrated equipment such as agitators, level sensors and CIP systems
- Insulation and temperature control
Materials and construction
Acid-resistant 316/316L has higher resistance to corrosion, especially in environments with chlorides and some acids, and is often used in more demanding applications such as process and food industries.
Pressurized and atmospheric solutions
Pressurized tanks require more robust materials and higher plate thickness, which increases the investment cost compared to atmospheric tanks. PED and CE certification also contribute to increased initial costs.
Applications in industry
- Food industry – high hygiene standards require 316L for certain liquids
- Chemical industry – aggressive chemicals require acid-resistant steel
- Pharmaceutical production – sterility and long-term sustainability guide material choices
- Water treatment – standardized solutions can be used with AISI 304
Technical options and equipment
- Stirrer (top or side mounted) in the same material
- CIP system and stainless steel spray balls
- Level and temperature sensors in compatible material
- Insulation with stainless steel protective shell
- PLC/SCADA integration for automated operation
Volumes and capacity
Larger tanks may in many cases have a lower cost per liter, but the total investment is influenced by several factors, of which the choice of material is an important part.
Used tanks may be an option with a lower initial cost, depending on the design and availability. At the same time, it is important to consider the condition of the material, previous use and what documentation is available.
These factors are important when assessing the conditions of the tank in the application in question.
Benefits of choosing the right materials
- Durability and longevity

Frequently asked questions about material selection and investment in process tanks
How do material choices affect investment costs?
Material selection is an important factor affecting the investment cost of process tanks.
Stainless 304 is common in many applications and can provide a lower cost per liter in less demanding environments. Acid-resistant 316/316L is often used for higher corrosion resistance requirements, which can mean a higher initial investment depending on the design and application.
The choice of material is influenced by technical requirements, budget and operating conditions. Process Surplus offers tanks in different materials and designs, where available information on specifications can be used as a basis for choosing a solution.
Which material is most cost-effective?
Stainless steel 304 is often a cost-effective option in standard applications with low corrosion risk.
In more demanding environments, such as aggressive fluids or higher hygiene requirements, acid-proof 316/316L is often used. This can mean a higher initial cost depending on the choice of material and design.
The choice of material can affect both cost and use over time, depending on operating conditions and application.
How does pressure class affect cost?
Pressurized tanks require thicker plate and certification according to PED/CE, which increases the investment cost compared to atmospheric tanks. Material selection must match pressure class for safe operation.
Can second-hand tanks reduce investment costs?
Yes, second-hand tanks can be a cost-effective option and contribute to a lower initial investment compared to new tanks.
At the same time, it is important to take into account factors such as the condition of the material, previous use and what documentation is available.
Process Surplus offers a wide range of used tanks in different designs and sizes, making it possible to find solutions to suit different types of industrial applications.
How to choose the right material for long-term investment?
Material selection is based on the properties of the fluid, hygiene requirements and the operating environment.
These factors influence the choice between stainless steel 304 and acid-proof 316/316L and how the tank can be used in the process.
Process surpluses offer tanks in these materials in various designs. Available information on specifications and construction can be used as a basis for investment and life cycle cost assessment.
