Duplex 2507 is known for its excellent corrosion resistance, especially in harsh environments containing chlorides. Austenitics are the easiest to weld and, at time of high strength (super duplex), this is also a negative aspect. Other standard stainless steel (above 304) is pretty great with corrosion resistance, but maybe no Duplex 2507 cannot perform in high corrosiveness. Because of the presence of austenitic and ferritic structures, duplex stainless steels provide two times strength compared to standard grades in this subclass &#8211; e.g. 100 ksi vs 200ksi &#8212; but they also benefit from synergies that enhance specific resistance against localized corrosion cases including pitting, crevice corrosion, stress cracking corrosion etc. As such, Duplex 2507 is often the preferred choice when corrosion resistance demands are high. But, super duplex stainless steel max temperature limitations are the facts. In addition, 2507 offers improved strength compared to common stainless steel grades with its higher range of yield strengths perhaps allowing the use of thinner material therefore reducing both costs and weight. This is not the case and you should know that 2507 as a material costs more just facing its major enhanced compound content and many other correspondents ask this question. Duplex 2507 also requires more finesse and experience to weld, as compared with regular grades of stainless steel which are simpler in this respect.<\/p>\n<h3><strong><span style=\"color: #3366ff;\">\u4e8c\u76f82507\u30b9\u30c6\u30f3\u30ec\u30b9\u92fc\u306e\u4fa1\u683c<\/span><\/strong><\/h3>\n<p>&nbsp;<\/p>\n<ul>\n<li>\u4e8c\u76f8\u92fc2507\u306f\u305d\u306e\u4e00\u4f8b\u3067\u3001\u5b9f\u306b\u9ad8\u4fa1\u3067\u3042\u308b\u3002\u3053\u308c\u306f\u3001\u305d\u306e\u5f37\u3044\u5408\u91d1\u542b\u6709\u91cf\u304c\u610f\u5473\u3059\u308b\u3082\u306e\u3067\u3042\u308b\u304c\u3001\u904e\u9177\u306a\u74b0\u5883\u306b\u3075\u3055\u308f\u3057\u3044\u6975\u7aef\u306a\u8010\u98df\u6027\u3092\u3082\u3082\u305f\u3089\u3059\u3002.<\/li>\n<\/ul>\n<h3><span style=\"color: #3366ff;\">\u4e8c\u76f8\u92fc2507\u30b9\u30c6\u30f3\u30ec\u30b9\u92fc\u3068\u30b9\u30fc\u30d1\u30fc\u4e8c\u76f8\u92fc\u306e\u9055\u3044\u3092\u77e5\u3063\u3066\u3044\u307e\u3059\u304b\uff1f<\/span><\/h3>\n<p>&nbsp;<\/p>\n<ul>\n<li>\u4e8c\u76f8\u92fc2507\u3068\u30b9\u30fc\u30d1\u30fc\u4e8c\u76f8\u92fc\u306f\u3001SGD (Super Grade-Duplex)\u30b9\u30c6\u30f3\u30ec\u30b9\u92fc\u306e\u4e00\u7a2e\u3067\u3042\u308b\u3002\u30b9\u30fc\u30d1\u30fc\u4e8c\u76f8\u92fc (PREN nos 40-45)\u306f\u3001\u901a\u5e38\u3001\u30d5\u30a7\u30e9\u30a4\u30c8\u76f8 \u3068\u30aa\u30fc\u30b9\u30c6\u30ca\u30a4\u30c8\u76f8\u304c\u307b\u307c\u7b49\u3057\u3044\u4e8c\u76f8\u5fae\u7d30\u69cb\u9020\u3092 \u7279\u5fb4\u3068\u3059\u308b\u3002.<\/li>\n<li>PREN is a numerical value primarily used to evaluate and compare corrosion resistance of different stainless steel alloy.
