magnetism stainless steel is also dirty

Exposed to the atmosphere and other materials , like grade 430 stainless steel is also dirty. However, rainfall, there is also a correlation between artificial irrigation and dirty surfaces.
Determine the effect of rainfall through the same lath directly on the atmosphere and on the covered areas. Human artificial washing effect is achieved by using six scrubbing sponge with soapy water to the right of each block is determined every slat . The results showed that , compared with the stainless steel 304 csp in place and covered the place not to be flushed through the rain wash and scrub the artificial surface and remove dust deposition on the surface of the case has a good effect. Has also been found , also affect the condition of the surface machining , the surface roughness of the smooth surface area slats slats better results .
