What is Stainless Steel 321 Sheet Made Of?

Stainless Steel 321 sheet is a high-performance alloy made from chromium, nickel, and titanium. This particular composition gives it great strength and exceptional corrosion and high-temperature resistance. The titanium is included as a stabilizer so that when used in high-temperature applications in 321, it retains its strength and integrity under stressful conditions.

In addition to the engineered functionalities, the titanium and chromium levels also allow for the distinct look of 321 stainless steel, whether for either internal or external use for architectural and design purposes. As an upper-end grade of steel, Stainless Steel 321 Sheet is a widely used steel in demanding industries like aerospace, where a project may involve complexity in strength, precision, and longevity.

FAQs

What is type 321 stainless steel?

Type 321 stainless steel is a titanium-stabilized austenitic stainless steel, offering corrosion resistance comparable to 304/304L stainless steel.

Is 321 SS better than 316 SST?

321 stainless steel and 316 stainless steel offer different advantages. 321 excels in high-temperature applications and maintains weld stability. 316 is the preferred choice for superior corrosion resistance, particularly in chemical and saltwater environments. The “better” option depends entirely on the specific application requirements.

What is the difference between 321 and 304 stainless steel?

321 stainless steel is preferred over 304 in industrial applications like chemical, coal, and petroleum industries that operate at high temperatures. 304 stainless steel is widely used in low-temperature applications like furniture decoration, food, and medical industries.

What grade is SS 321 equivalent to?

Stainless steel 321 is similar to grade 304 when annealed. However, it offers better corrosion resistance, especially after welding if it hasn’t been heat-treated, or when used in temperatures between 425 and 900°C

What is the difference between 321 and 321H stainless steel sheets?

The main difference between 321 and 321H stainless steel sheets boils down to strength and workability, especially at high temperatures. 1  Regular 321 is your workhorse – good for welding and general toughness, but not heat-treatable for extra strength. 321H, however, gets a heat treatment that boosts its strength when it’s hot and makes it easier to form. So, if your project involves high heat and needs a bit more oomph or shaping, 321H is likely the better bet. When you’re deciding, just weigh up what’s most important for your specific needs – temperature resistance, strength, corrosion protection, and how easy it is to work with.
