the raw material of s/s drink bottle

Material of stainless steel drink bottle 

the material of  s/s drink bottle  is 304 s/s , 316 s/s and 201 s/s  in the market .304 s/s and 316 s/s have high quality , the hardness of 304 s/s and 316 s/s  are similar . The chemical composition of 316 s/s  have more than 2% Ni, so 316 s/s has better corrosion resistance than 304 s/s . 304 s/s is widely used in the s/s industry. It has good corrosion resistance ,high temperature resistance and acid resistance . compare with  201 s/s , 201 s/s has not so good corrosion resistance . Because  of 201 s/s has low chemical composition of Ni, if save and use 201 s/s in bad enviroment .after a period time , the r are ust.
