Stainless Steel 321 Spools are made from a material that is similar to 304 Stainless Steel but with an addition of Titanium. It has excellent corrosion resistance and is particularly useful in high-temperature environments. Other names for this steel include AISI 321 and Remanit 4541. The tensile strength and yield strength ranges are typical for the material.


Stainless Steel 321 has excellent welding, forming, and mechanical properties. Unlike Type 304, 904L ASTM A 815 is less susceptible to creep and is better suited for high-temperature operations. Stainless Steel 321 also withstands high levels of heat and doesn't require annealing after welding. 


This material also demonstrates a high degree of toughness, particularly at cryogenic temperatures. It is preferred over 304 because it has improved resistance to creep, while 304 is susceptible to stress corrosion cracking.


Stainless Steel 321 Spools are a popular material for welding and are a great choice for high-temperature applications. This material's properties make it perfect for a variety of applications, from fast-fastening to welding heavy components. And it is resistant to intergranular corrosion. 


Despite its high price, this metal is incredibly versatile. Stainless Steel 321 Spools are the best way to make the most out of a welding project.
