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 material.

Possible Alternative Grades
Possible alternative grades to grade 321 stainless steels are given in table 5.
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.
