Nitric acid media most common metal corrosion in nitric acid was rapidly destroyed, stainless steel is the most Gate Valves widely used nitric acid-resistant materials, all concentrations of nitric acid at room temperature have good corrosion resistance, it is worth mentioning that the stainless steel containing molybdenum ( such as 316,316 L) of nitric acid corrosion resistance is not only no better than ordinary stainless steel (eg 304,321), and sometimes even better.

硝酸介质一般金属大多在硝酸中被迅速腐蚀破坏，水力控制阀不锈钢是应用最广的耐硝酸材料，对常温下一切浓度的硝酸都有良好的耐蚀性，值得一提的是含钼的不锈钢（如316、316L）对硝酸的耐蚀性不仅不优于普通不锈钢（如304、321），有时甚至不如。

Twice a year Northwestern Georgia celebrates its cultural traditions on the grounds of a historic water-powered mill. The Prater Mill, located on the Coahulla Creek, was built by Benjamin Franklin Prater in 1855. During the Civil War, the mill was used as a campsite for soldiers on both sides. Since it was considered an important source of food, it was not destroyed. The Prater family operated the mill until the 1950s.

住在乔治亚西北部的居民，每年会在具历史意义的水力面粉厂内举办两次庆祝当地文化传统的庆典；座落於 Coahulla Creek 的普拉特面粉厂建於1855年，建造者是班杰明普拉特；内战时，这间面粉厂曾被敌对的双方拿来做为军营，因为它是重要的食物来源，所以未遭摧毁；直到1950年前，这间面粉厂的经营者一直是普拉特家族。
