725LN雙相鋼#耐腐蝕鋼板725LN奧氏體不銹鋼 Austenitic stainless steel. Plate for 724 l and 725 ln for carbamate solution at high temperature, formate solution has the very strong corrosion resistance of steel plate. This environment is when ammonium carbamate in urea steel production of ammonia and carbon dioxide as reaction media from time to time. Both steel grade urea equipment in high temperature high pressure parts of the carbamate in the environment of local corrosion has a strong resistance. Otto quinlan's plate for 724 l and 725 ln the huey test weight loss and local corrosion are rarely. Plate for 724 l and 725 ln austenitic stainless steel plate structure is all non-metallic impurity content and rare.
