Benefits Of Using 321 Stainless Steel Sheet

The variations in the additions used with stainless steel create products that are more or less resistant to specific types of environments. 321 stainless steel sheet is very similar in basic composition to the durable 304 grade of stainless steel, but it is much more heat resistant.

The Titanium Difference

The heat resistance found with 321 stainless steel sheet or bars is due to the addition of titanium. While there is a only a small percentage of titanium used, usually less than 0.7%, the result is a stainless steel that is capable of withstanding use in temperatures of 800 to 1500 degrees Fahrenheit. This temperature range makes it an excellent choice for use in the refining and aerospace industries as well as in heating, engines and chemical applications.

With the addition of titanium and as much as five times the carbon content, the resulting sheet or plate is virtually free from any issues with chromium carbide precipitation that is problematic with other stainless steel grades. This makes it a good option for welding as well as for use in very high temperature such as jet engines and in refining processes.

Cold Temperature Versatility

While many applications of 321 stainless steel sheet recommend this grade because it can handle heat well, it is also a good option for use in very cold temperatures. It can be used even in cryogenic applications and environments, making this an extremely valuable material in many types of research and industry uses.

Although not a highly polished type of stainless steel, it is ideal for parts and equipment for its versatility and durability.


321 stainless steel sheet is well known for its durability over long periods of time. This includes resistance to corrosion and scaling while also exhibiting high levels of phase stability. Another feature of this grade of stainless steel is that it is not prone to vibration fatigue, an important consideration when used in the aerospace industry or for manufacturing of heating, refining and processing equipment and parts.

321 stainless steel sheet materials come in a range of thicknesses that can range from as small as 0.1 inches to up to 0.1875 inches. Companies can customize sheeting to meet your requirements for any project, large or small.
