Guide to Stainless Steel 321 Sheets

What are Stainless Steel 321 Sheets?

Stainless steel 321 sheets are a type of austenitic stainless steel that contains titanium as a stabilizer. It is a modified version of stainless steel 304 with higher corrosion resistance, especially in high heat and acidic environments. 

The addition of titanium in the alloy makes it less susceptible to corrosion, which increases its longevity. Unlike stainless steel 304, limited to a maximum temperature of 800°C, Stainless Steel 321 Sheets can withstand temperatures up to 900°C.

Applications of Stainless Steel 321 Sheets

Stainless Steel 321 Sheets are used in various applications, especially in industries requiring high temperature and corrosion resistance. Aerospace engineers use Stainless Steel 321 sheets to manufacture jet engine parts exposed to high heat.

The chemical industry uses Stainless Steel 321 sheets to manufacture corrosive chemicals like ammonium and sulfuric acid. The food processing industry uses Stainless Steel 321 sheets to produce equipment that comes into contact with food, as it is resistant to corrosion and does not contaminate food.

Advantages of Stainless Steel 321 Sheets

There are many advantages to choosing Stainless Steel 321 sheets over other stainless steel types. One advantage is its high resistance to corrosion, oxidation, and high temperatures. For example, Stainless Steel 321 sheets are resistant to intergranular corrosion, which means it does not rust along the grain boundaries. Another advantage is its excellent weldability, which reduces cracking, and its high strength, enhancing durability.
