    High Strength\u30fbLow Weight<\/h3>\r\n

    The 0.2% bearing force is approximately twice of SUS304, which make thin-walled lightweight design possible.<\/p>\r\n <\/li>\r\n

    High Corossion Resistance<\/h3>\r\n

    Same anti-corrosion as SUS304<\/p>\r\n <\/li>\r\n

  • \r\n

    Stable Price<\/h3>\r\n

    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%.<\/p>\r\n <\/li>\r\n <\/ul>\r\n <\/div>\r\n <\/div>\r\n\r\n
