How does stainless steel prolong service life?

What the use of stainless steel changes as economic development is more extensive, people is in daily life with be closely bound up of stainless steel goods, but a lot of people are not much to the function understanding of stainless steel, think stainless steel never rusts.

Actually, the corrosion resistance of stainless steel good, because the surface forms a rarefied film,be, in nature, the existence of its configuration with stabler oxide. But although stainless steel differs by use condition, oxidation level is different, but be oxidized finally, this kind of phenomenon makes corrode normally.

Surface of stainless steel goods is rarefied in film anti-corrosive the position with weak ability, as a result of bare in the metal of corrosion environment exterior happening report is changed or chemistry reacts, form the imagination that nod corrode thereby, generate alveolus, be close to plus ion having oxygen, fashion very strong caustic solution, corrode the speed of reaction quickly.

To prolong stainless steel service life, corroded phenomenal classification and measure to sum up the following in the light of what stainless steel appears likely:

1, clean a method

When washing stainless steel face, must notice not to produce exterior cut phenomenon, avoid to use ball of the catharsis fluid that blanchs composition and abrasive, steel wire, sharpener to wait, to get rid of catharsis fluid, clear water of the reoccupy when catharsis ends rinses the surface.

2, how is dirt handled

Stainless steel surface has dirt and easy get rid of the usable soap weak scour of contamination will wash, binder composition, use alcohol or organic dissolvent (ether, benzene) swab.

3, grease

The grease of stainless steel surface, oil-lubricated oily pollution, after using soft cloth wipe up, use neuter scour or ammoniac solution or with special scour catharsis.

4, acidity is corroded

Stainless steel surface has bleacher and all sorts of acid are adherent, rinse with water instantly, reoccupy ammonia solution or dip of solution of mineral of neuter carbonic acid are washed, with neuter scour or warm water catharsis.

5, exterior rainbow grain

Stainless steel surface has rainbow grain, it is to use scour or oil to cause too much, scour of Wen Shuizhong sex is used when catharsis but scour off.

6, adherent rust

The rust that contamination of stainless steel surface causes, can use 10% nitric acid or abrade scour catharsis, also can use catharsis of special catharsis medicines and chemical reagents.
