What exactly is Stainless Steel 304 Plate?

Stainless Steel 304 is also called 18/8 stainless steel by most of the people. And it is due to the typical formula by which it is made 18% chromium and 8% nickel. That particular mix? It gives it fantastic resistance to a real wide range of things that can cause corrosion – stuff in the atmosphere, different chemical and even food-related environments. Its austenitic structure, well, that provides excellent toughness, even when you get down to those super cold, cryogenic temperatures.

Now, Stainless Steel 304 (SS 304 for short) is pretty much the most widely used austenitic stainless steel grade you’ll find anywhere, globally. It’s really known for its excellent combination of features: great corrosion resistance, good formability, it’s easy to weld (weldability, that is), and its strength. Because of all that, stainless steel 304 plates and stainless steel 304 sheets are, you could say, fundamental materials used across just countless industries. So, whether you find you need a robust 304 plate for some structural applications, or a precise 304 sheet for some fabrication work, this versatile alloy just delivers reliable performance.

Frequently Asked Questions

What is a 304 stainless steel plate?

304 and 304L ASTM A240 stainless steel plate is a standard 18-8 material – meaning it contains 18% chromium and 8% nickel. 304 Stainless steel plate is one of the most versatile stainless steel materials available.

Is 304 stainless steel good quality?

304 stainless steel is the most common form of stainless steel used around the world due to excellent corrosion resistance and value. 304 can withstand corrosion from most oxidizing acids. That durability makes 304 easy to sanitize, and therefore ideal for kitchen and food applications.

How much is a 304 stainless steel sheet?

0.09" Stainless Sheet 304-Annealed 2B - 12″ X 12″ (1 X 1 ft.) - $35.81 ea. 12″ X 24″ (1 X 2 ft.) - $69.47 ea.

What's the main difference between a 304 plate and a 304 sheet?

The primary difference is thickness. Generally:
*304 Sheet (Stainless Steel 304 Sheet): Material less than 6mm (approx. 1/4 inch) thick.
* 304 Plate (Stainless Steel 304 Plate): Material 6mm (approx. 1/4 inch) thick or greater.
Plates are typically used for more structural or heavy-duty applications, while sheets are common for lighter fabrication, paneling, and appliances.

Is Stainless Steel 304 magnetic?

In its fully annealed (softened) state, SS 304 is essentially non-magnetic (a very slight magnetic response might be detectable). However, cold working (like bending, forming, or drawing during sheet production) can induce some magnetism in the material.

Can Amardeep Steel cut SS 304 plates and sheets to custom sizes?

Yes, Amardeep Steel offers value-added processing services, including precision cutting, shearing, and slitting to meet your specific dimensional requirements for both 304 plates and 304 sheets.

How do I get a price for 304 stainless steel plates or sheets from Amardeep Steel?

The best way to get an accurate and current 304 stainless steel plate price or sheet quote is to contact us directly. Pricing depends on current market conditions, the required dimensions (thickness, width, length), quantity, finish, and any processing needed.
