Stainless steel duplex stainless steels are achieved with an overall lower alloy content than similar-performing super-austenitic grades, making their use cost-effective for many applications. Duplex grades are characterized into groups based on their alloy content and corrosion resistance. Precipitation hardening stainless steels have corrosion resistance comparable to austenitic varieties, but can be precipitation hardened to even higher strengths than the other martensitic grades. The most common, 17-4PH, uses about 17% chromium and 4% nickel. The designation "CRES" is used in various industries to refer to corrosion-resistant steel. Most mentions of CRES refer to stainless steel, although the correspondence is not absolute, because
US Mexico Trade Dispute - Stainless Steel Sheets and Coils dumping practices and methodologies implemented by the US impaired and nullified the benefits added to Mexico, directly or indirectly, under the WTO Agreement on Customs Valuation, and that the anti-dumping laws were unwarranted. The consultations were held to discuss activities carried on between January 1999 and June 2004. This led to a panel being established in December 2006, the proceedings of which continued until May 2013, with a mutually agreeable solution being reached. Japan asked to join the consultation in June 2006. Stainless steel, specifically in the form of sheets and coils, was at the center of the dispute. Stainless steel
