Stainless steel of 304 does not contain titanium and niobium which will have a tendency to intergranular corrosion. We need to know this situation before we get them from stainless steel supplier in China and take some methods to protect them in the daily use.
 
Stainless steel 304, if added titanium and niobium together with the stabilization process, can reduce intergranular corrosion. It is a high-alloy steel resistant corrosion in the air or chemical corrosion and it has a beautiful surface and good corrosion resistance when we get them from wholesale 316L stainless steel.Without going through the plated surface treatment, and it plays inherent in the surface properties of stainless steel for use in multiple one kind of steel areas, commonly referred to as stainless steel. Representative of the performance of 13 chrome steel, 18-8 chrome-nickel steel alloy.
 
From the metallographic point of view, because the chromium film formed on the surface of high quality 304 stainless steel which contains chromium leaving the thin, the membrane separating invasive oxygen within the steel from corrosion effect.
