Precision engineering meets durability: 321 stainless steel bar

Heat-resistant and corrosion-resistant: the unbeatable combination of 321 stainless steel bar.

The 321 stainless steel bar strengthens the material, making it less susceptible to intergranular corrosion. As a result, 321 is the stainless steel of choice for applications requiring temperatures up to 900° C.

Even at cryogenic temperatures, the steel possesses outstanding forming and welding properties, as well as excellent toughness. If you need stainless steel that resists intergranular corrosion, 304L is the most typical choice because it is the most widely used and supplied steel. But 321 stainless steel bar is also a good addition to the stainless steel market.
