201 is a kind of stainless steel grade under the standard ASTM A240/A240M. 201 stainless steel is a kind of steel which is resistant of weak corrosion medium such as air, steam and water, ect. 201 stainless steel material has a certain performance of acid, alkali resistance, high density, polishing without bubble, pinhole, etc. ASTM 201 is the grain material of producing all kinds of watch case, strap bottom cover etc. It is mainly used for a decorative tube, industrial pipe and some shallow tensile products.

201 stainless steel chemical composition:

C ≤	Si ≤	Mn ≤	P ≤	S ≤	Cr	Ni	N
0.15	1.0	5.5-7.5	0.06	0.03	16.0-18.0	3.5-5.5	≤0.25
