When selecting a metal straw that must endure corrosive environments, Two of the more commonly used grades of austenitic stainless steel are grades 304 and 316. This blog is to help you determine which grade is right for your straw.
304 Stainless Steel
Grade 304 stainless steel is generally regarded as the most common austenitic stainless steel. It contains high nickel content that is typically between 8 and 10.5 percent by weight and a high amount of chromium at approximately 18 to 20 percent by weight. Other major alloying elements include manganese, silicon, and carbon. The remainder of the chemical composition is primarily iron.The high amounts of chromium and nickel give 304 stainless steel excellent corrosion resistance.
