Duplex Stainless Steel Square Pipes

SUS821L1(NSSC 2120®)

Square Pipe Less Resource Stainless

NSSC 2120® is Nippon Steel Corporation's registrated trade-mark.

  • High Strength・Low Weight

    The 0.2% bearing force is approximately twice of SUS304, which make thin-walled lightweight design possible.

  • High Corossion Resistance

    Same anti-corrosion as SUS304

  • Stable Price

    Reduce the amount of Ni, a rare metal with high price fluctuations.
    The amount of Ni in SUS821L1(NSSC 2120®) is only 2% compared to SUS304 which is 8%.

Duplex stainless steel and square pipes enable high-strength exploitation through reduced thickness and weight.
