What does 304 grade mean in stainless steel?


What does 304 grade mean in stainless steel?

What does 304 grade mean in stainless steel?
Stainless steel is used in the manufacturing of a range of tools and consumer products, but often it is hard to figure what does different grade stainless steel mean and their purpose.

Today in this article, we will discuss all the important details about 304 stainless steel and what’s the difference between 304-grade steel and other grade steel.

What is stainless steel 304?

304 stainless steel is the kind of stainless steel that is readily available in the market. This stainless steel consists of 18-20% chromium and 8-10% nickel as its main non-iron constituents.

Moreover, 304 stainless steel is comparatively less conductive than carbon steel, and it is also an austenitic metal.

One of the prominent properties of this steel is that it has a lower tendency to corrode than any regular steel. The tendency to be molded in different shapes is one of the most prominent reasons for the usage of this steel.

Advantages of 304 stainless steel

• Excellent corrosion and inter granular resistance 
• Remarkable cold and hot forming and performance 
• Commendable low temperature performance 
• Durable
• Exceptional welding property

Disadvantages of 304 stainless steel

• Intergranular resistance may increase after welding as it makes the steel more sensitive and vulnerable to wear and tear
• 304 grade steel is also sensitive to stress corrosion 
• Despite having a good molding strength, the 304-grade stainless steel has relatively low mechanical strength thus, leading to poor cutting performance

304 vs 316 stainless steel:

The first thing to highlight is the austenitic nature of both of these steel grades and also the high levels of non-iron constituents like Chromium and Nickel.

Chromium present in both of these types of stainless steel increases the tensile strength of the metal and makes it highly efficient against corrosion and daily wear and tear.

Whereas, the Nickel provides extra strength and sturdiness without compromising the ductility and toughness of the metal.

What separates both of them?

The key difference between both stainless steels is the composition. Where it’s true that both of them have high levels of chromium and nickel, but they still differ in composition.

The 316-grade stainless steel consists less of chromium and more of nickel and molybdenum, which affects the steel's properties too.

This leads to 316 grade being more corrosion-resistant especially, to chloride and acids and that’s why this stainless steel is used in the manufacturing of medical equipment, food processing equipment, brewing facilities, etc.

However, the standard 304-grade stainless steel provides adequate durability and strength for storage tanks, appliances, electrical enclosures, etc.

Which stainless steel is food grade?

304 stainless steel is still the most popular food-grade stainless steel. Food grade steel is basically a certified grade of steel in terms of its composition, which is safe to use with food, be it in packaging or manufacturing or for any other purpose.
