09 May, 2023

Stainless steel is a widely used material in various industries due to its exceptional properties and versatility. One of the most common stainless steel grades is 304 stainless steel. Let's learn more about 304 stainless steel according to this article.

What Is 304 Stainless Steel?

304 stainless steel is a popular austenitic stainless steel alloy containing high levels of chromium and nickel. It is known for its excellent corrosion resistance, durability, and versatility, making it suitable for a diverse range of applications. The 304 in its name alludes to the alloy's particular composition, which indicates that it comprises around 18% chromium and 8% nickel.

Composition of 304 Stainless Steel

The composition of 304 stainless steel is carefully balanced to provide its exceptional properties. The main elements present in this alloy include:

Chromium (Cr): Chromium is a vital component of stainless steel, contributing to its corrosion resistance. The chromium percentage of 304 stainless steel is normally approximately 18%, providing a protective oxide coating on the surface that resists corrosion and tarnishing.

Nickel (Ni): Nickel improves 304 stainless steel's corrosion resistance and hardness. Nickel, which has an estimated composition of 8%, also helps to the material's capacity to tolerate high temperatures.

Carbon (C): Carbon is a critical component of stainless steel, and the regulated quantity of carbon in 304 stainless steel achieves the required balance of strength and weldability.

Manganese (Mn): Manganese is added to increase the material's formability and strength, as well as its resistance to corrosion in particular situations.

Silicon (Si): Silicon helps to improve the scaling resistance and oxidation resistance of 304 stainless steel at high temperatures.
