Physical Properties of Stainless Steel:
The reason for choosing stainless steel is normally due to
advantages given by physical properties such as corrosion
resistance.
In addition to corrosion resistance, the advantageous physical
properties of stainless steel include:
- High and low temperature resistance
- Ease of fabrication
- High Strength
- Aesthetic appeal
- Hygiene and ease of cleaning
- Long life cycle
- Recyclable
- Low magnetic permeability

Which Should You Use: Grade 304 or Grade 316?
Here are some situations where 304 stainless steel may be the
better choice:
- The application requires excellent formability. The higher
molybdenum content in Grade 316 can have adverse effects on
formability.
- The application has cost concerns. Grade 304 is typically more
affordable than Grade 316.
Here are some situations where 316 stainless steel may be the
better choice:
- The environment includes a high amount of corrosive elements.
- The material will be placed underwater or be exposed to water
consistently.
- In applications where greater strength and hardness are required.
