Stainless Steel Grade AISI 304N | S30451

AISI 304N | S30451 - The stainless steel version of AISI 304 is strengthened by adding nitrogen to its composition. This means that when comparing the two grades, AISI 304N has a higher tensile strength. This makes it an ideal material for applications where strength is important, such as in the marine environment or in manufacturing projects requiring high-strength materials.

Austenitic AISI 304N stainless steel has better corrosion resistance than AISI 302 steel. It has high ductility, excellent drawing and forming properties. The alloy is essentially non-magnetic, becoming slightly magnetic when cold worked. Low carbon content means less carbide precipitation in the heat-affected zone during welding and less susceptibility to intercrystalline corrosion.
