We wash our kitchenware by scourer which made by stainless steel sometimes for the hard dirty kitchenware. Saying scourer is a small scale from the stainless steel supplier in China. Now we can see the whole world of stainless steel as I have this kind of resource to tell you that.
 
First of all, we should figure out the special number of 301,302,303,304, 310 and 316 and so on for the description of stainless steel. For example, T-303 is one of the 3 main alloys of commercially available stainless steel. It has mechanical properties that are comparable to both 304 and 316 stainless from wholesale 316L stainless steel. The primary reason to use 303 is when you need a stainless steel with machining capabilities better than that of 304 and 316. It has roughly the same corrosion resistance as 304, but not as well as 316.
 
We think about high quality 304 stainless steel when we use any stainless steel for our daily life. However, we can see other stainless steels too for the big world’s scale.
