SAE 304 stainless steel optimal high temperature strength. The carbon content of 304L (UNS 30403) is restricted to a maximum of 0.03%, which prevents sensitization during welding. Sensitization is the formation of chromium carbides along grain boundaries when a stainless steel is exposed to temperatures in the range of ~–. The subsequent formation of chromium carbide results in reduced corrosion resistance along the grain boundary leaving the stainless steel susceptible to unanticipated corrosion in an environment where 304 would be expected to be corrosion resistant. This grain boundary corrosive attack is known as intergranular corrosion. The carbon content of 304 (UNS 30400) is restricted
US Mexico Trade Dispute - Stainless Steel Sheets and Coils dumping US Mexico Trade Dispute - Stainless Steel Sheets and Coils dumping The US-Mexico Trade Dispute - Stainless Steel Sheets and Coils dumping is a trade dispute between the governments of The United States and Mexico. On May 26, 2006 Mexico requested consultations with the United States about a number of final anti-dumping judgments made by the US Department of Commerce. The judgments concerned the imports of stainless steel sheets and strips from Mexico, which were supposedly illegal dumping through the use of a "Zeroing" technique by the US Department of Commerce. Mexico believed that some of the laws, regulations, administrative
