What is the difference between 321 and 321H stainless steel sheet?
321 and 321H stainless steel sheet offer different levels of strength and corrosion resistance. 321 is a
non-heat treatable type of stainless steel that is typically used for applications that require
weldability and toughness. On the other hand, 321H is a heat-treated version of 321 stainless steel that
exhibits higher strength at elevated temperatures and offers better formability. It's often used in more
demanding environments where its ability to withstand high temperatures makes it a preferred choice.
Ultimately, selecting the correct grade for an application will depend upon the application's
requirements regarding temperature, strength, corrosion resistance, and formability.
What is 321 stainless steel sheet made of?
321 stainless steel sheet is an alloy composed of chromium, nickel, and titanium and has excellent
corrosion resistance as well as heat resistance. It is a preferred choice for high-temperature
applications because it won't distort or harden in extreme temperatures. The high chromium and titanium
content also gives 321 stainless steel its unique design and aesthetic that is attractive for indoor or
outdoor applications. This premium grade of steel has been used by a variety of industries, including
aerospace, to enable complex projects that require strength, precision, and durability.
We also supply make of SAIL / ESSAR / JINDAL / TATA / BHUSHAN/ INDIAN / IMPORTED etc

|
Possible alternative grades to 321 grade stainless steel
|
| Grade |
Why it might be chosen instead of 321 |
| 304L |
The requirement is for resistance to intergranular
corrosion, not for high temperature strength |
| 3CR12 |
Only mild "high temperature" environment is present…
up to about 600°C. |
| 304H |
Only mild "high temperature" environment is present…
up to about 800°C. |
| 310 |
The temperature of the operating environment is up to
about 1100°C - too high for 321 or 321H. |
S30815
(253MA) |
The temperature of the operating environment is up to
about 1150°C- too high for 321 or 321H. |
