Stainless Steel Coil 201

Stainless Steel Coil 201

Chemical composition(WT%) (C) :≤0.15 (Si) :≤0.75 (Mn) :5.5 to 7.50 (Cr) :16.0 to 18.0 (N) :≤0.25 (P) :≤0.060 (S) :≤0.030 (Ni) : 0.8 to 1.2% (Cu) : Half 0.8% ,High 1.5% Our 201 stainless steel is characterized by acid resistance, alkali resistance, high density, no polishing bubbles, no pinholes,...


The 201 stainless steel sheet has the ability to withstand general corrosion similar to the unstable nichrome 304. Its prolonged heating in the temperature range of chromium carbide may affect the alloy 321 stainless steel plate and 347 in harsh corrosive media. It is mainly used in high temperature applications, and high temperature applications require strong sensitization of materials to prevent intergranular corrosion at lower temperatures. It has the characteristics of polishing without bubbles, no pinholes, etc. It is a high-quality material for producing various case and strap bottom cover.
