data-end=\"21942\">Duplex stainless steel 2205<\/strong> has become one of the most widely recognized 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
