How to Choose Hot Rolled Stainless Steel Plate？

How to Choose Hot Rolled Stainless Steel Plate

1. Material Grade

Choose the appropriate stainless steel grade based on the application:

• 304: General-purpose; good corrosion resistance.

• 316: Better corrosion resistance; ideal for marine or chemical environments.

• 321: High-temperature resistance.

• 310S: Excellent high-temperature oxidation resistance.

• 2205 (Duplex): High strength and good stress corrosion resistance.

2. Thickness and Size

Determine the required thickness, width, and length based on your structural or fabrication needs. Common thicknesses range from 3mm to 100mm+.

3. Surface Finish

Hot rolled plates typically have a No.1 finish (rough, scaled surface). Consider if further surface treatment (e.g., pickling, grinding) is needed for your application.

4. Mechanical Properties

Check the yield strength, tensile strength, and elongation to ensure the material meets your mechanical performance requirements.

5. Flatness and Tolerances

Confirm the flatness and dimensional tolerances with the supplier, especially for precision applications.

6. Standards and Certifications

Ensure the material complies with relevant standards such as:

• ASTM A240 / A480

• EN 10088-2

• JIS G4304

Also ask for Mill Test Certificates (MTC) or Material Certificates (EN 10204 3.1/3.2).

7. Supplier Reputation

Choose a reliable supplier with:

• Consistent product quality

• On-time delivery

• Good after-sales service

8. Price vs. Performance

Compare prices, but also factor in quality, origin of the steel (e.g., Europe, Japan, China), and long-term durability.
