200

201

12Cr17Mn6Ni5N

It has the characteristics of acid   resistance, alkali resistance, high density, no bubbles, no pinholes, etc. It   is a high-quality material for producing various case and strap bottom cover.

Mainly used for decorative tubes,   industrial tubes, some shallow stretched products.

202

12Cr18Mn9Ni5N

 

Replacing part of nickel with Mn and N to   obtain good mechanical properties and corrosion resistance. It is a new type   of nickel-free stainless steel. Its room temperature strength is higher than   304, and it has better oxidation resistance below 800 degrees. Medium   temperature intensity

Mainly used for decorative tubes,   industrial tubes, some shallow stretched products.

2205

00Cr22Ni5Mo3N

 

Its Cr, Mo and N elements are relatively   narrow, easy to achieve phase balance (ie, two phases are about half),   improve the strength, corrosion resistance and weldability of steel, and are   often used for high performance requirements and welding. Materials such as   oil and gas pipelines.

Used in refining, chemical fertilizer,   paper, petroleum, chemical and other heat exchangers and cold showers and   devices resistant to seawater, high temperature and concentrated nitric acid.
