Hunan Hemway Steel Co., Ltd.
Grade 316 stainless steel is an austenitic form of stainless steel with a molybdenum content of 2-3%. The addition of molybdenum makes the metal more resistant to pitting and corrosion and improves its resistance to exposure to high temperatures. This grade of stainless steel is particularly effective when used in acidic environments. With this metal, corrosion caused by acetic acid, hydrochloric acid and other forms of acid can be prevented.
