Application
|
|
SS304
|
Drink water, None Corrosive Liquid, Oils, Fresh Steam etc.
|
|
SS316L
|
Well water, river water, closed circulating water and other water with complex components, Dilute sulfuric acid with temperature ≤ 50 ℃ and concentration ≤ 10% etc.
|
|
Titanium
|
Liquid that contains chlorine iron, Sea water etc.
|
|
Titanium Alloy
|
Higher temperature and corrosion resistance than titanium.
|
|
Nickel 20
|
It is mainly used for caustic solution (NaOH, Koh, etc.) with high concentration (50% ~ 70%) and high temperature (boiling point).
|
|
Hastelloy C-276
|
It has good corrosion resistance, almost not affected by Cl -, excellent corrosion resistance to various concentrations of
sulfuric acid, and is one of the few materials that can be used in hot concentrated sulfuric acid, widely used in organic acids (such as formic acid, acetic acid), high temperature HF acid and a certain concentration of hydrochloric acid (< 40%), phosphoric acid (< 50%); chloride, fluoride. |
