201 Stainless Steel

Short Description:

Product introduction

Mainly used for decorative pipe, industrial pipe, some shallow tensile products.201 stainless steel plate has the ability to resist general corrosion similar to the unstable nichcr 304. Prolonged heating of 201 stainless steel plates in the chrome-carbide degree temperature range may affect alloy 321 stainless steel plates and 347 in harsh corrosive media. 201 Stainless steel plates are mainly used for high temperature applications, which require the material to have strong sensitization resistance to prevent intergranular corrosion at lower temperatures.
