Stainless Steel 304 Plates

Stainless Steel 304 Plates

Stainless Steel 304 Plates (ASTM A240 TP304) are austenitic chromium-nickel stainless steel plates containing approximately 18% chromium and 8% nickel, commonly referred to as “18/8” stainless steel.

These plates offer excellent corrosion resistance, good mechanical strength, high formability, and outstanding weldability, making them one of the most widely used stainless steel grades globally.

SS 304 Plates are extensively used in structural, chemical, food processing, pharmaceutical, architectural, and industrial applications due to their resistance to oxidation, atmospheric corrosion, and mild chemical exposure.

Types of Stainless Steel 304 Plates

  • Hot Rolled (HR) SS 304 Plates
  • Cold Rolled (CR) SS 304 Plates
  • 2B Finish SS 304 Plates
  • BA Finish SS 304 Plates
  • No.4 Finish SS 304 Plates

Manufacturing Process of SS 304 Plates

  • Melting and refining (EAF)
  • Argon Oxygen Decarburization (AOD)
  • Continuous casting into slabs
  • Hot rolling
  • Annealing
  • Pickling
  • Leveling and cutting
  • Inspection and testing

Corrosion Resistance Mechanism

SS 304 Plates derive corrosion resistance from a passive chromium oxide layer that protects against oxidation and corrosion.

However, in chloride-rich environments, pitting corrosion may occur, making SS 316 a better alternative.

FAQs on Stainless Steel 304 Plates

1. What is the difference between SS 304 and SS 304L?

304L has lower carbon, reducing intergranular corrosion after welding.

2. Can SS 304 Plates be welded?

Yes, they offer excellent weldability.

3. Are SS 304 Plates suitable for high temperatures?

For high temperatures, 304H is recommended.

4. Are SS 304 Plates corrosion resistant?

Yes, due to chromium oxide passive layer.

5. Do you provide MTC?

Yes, all plates are supplied with Mill Test Certificates.
