duplex stainless steel grades because it does not depend on being the absolute best at one single property.<\/p>\n<p data-start=\"22097\" data-end=\"22122\">Its advantage is balance.<\/p>\n<p data-start=\"22124\" data-end=\"22136\">It combines:<\/p>\n<p data-start=\"22138\" data-end=\"22264\"><strong data-start=\"22138\" data-end=\"22264\">High strength + chloride corrosion resistance + useful weldability + relatively moderate alloy cost + mature global supply<\/strong><\/p>\n<p data-start=\"22266\" data-end=\"22462\">That makes it particularly attractive for applications where 316L is approaching its performance limits but 2507 or nickel alloys would provide more performance than the project actually requires.<\/p>\n<p data-start=\"22464\" data-end=\"22510\">For buyers, however,

Purchase the correct duplex grade, product standard, dimensions, delivery condition, testing and documentation for your application.<\/strong><\/p>\n<\/blockquote>\n<p data-start=\"22699\"
