When buying stainless steel flanges, a lot of my friends do not know how should buy. It could easily deceived. Stainless steel flange on the market is extremely strong, so many unscrupulous traders, in order to reap huge profits, what do unethical things out. This is more a test that we are not having a pair of "eyes" see through all of the scam, very good to protect their legitimate rights and avoid fooled.
