304 zanglamaydigan po'latdan zang paydo bo'lishining sabablari

Xlorid ionlari tuz, ter, dengiz suvi, dengiz shabada, tuproq va boshqalar kabi keng tarqalgan. Xlorid ionlari mavjud bo'lgan muhitda zanglamaydigan po'lat tez korroziyaga uchraydi va hatto oddiy past karbonli po'latdan ham oshib ketadi. Xlorid ionlari qotishma elementlarda Fe bilan kompleks hosil qiladi, bu Fe ning musbat potentsialini kamaytiradi, so'ngra elektronlarni olib tashlash uchun oksidlovchi tomonidan oksidlanadi.

Therefore, there are requirements for the use environment of stainless steel, and it is necessary to wipe frequently to remove dust and keep it clean and dry.

316 and 317 stainless steels are molybdenum-containing stainless steels. Molybdenum content in 317 stainless steel is slightly higher than 316 stainless steel. Because 316 stainless steel contains molybdenum, its overall performance is better than 310 and 304 stainless steel. Under high temperature conditions, when the sulfuric acid concentration is lower than 15% and higher than 85%, 316 stainless steel has a wide range of uses. 316 stainless steel also has good resistance to chloride attack, so it is usually used in marine environments.
