On the market Common 304 stainless Steel coil marking method has 0cr18ni9,sus304, of which 0cr18ni9 generally indicates the national standard production, 3,041 like ASTM Standard production, SUS 304 represents the daily standard production.
304 stainless steel coil after cold processing, the tissue structure will also be converted to martensite, the greater the deformation of cold processing, the more martensite conversion, the greater the magnetism of steel.
In order to maintain the corrosion resistance inherent in 304 stainless steel coils, steel must contain more than 18% chromium and more than 8% nickel content.
Etching processing method, is on the stainless steel surface using screen printing acid protection film, and then etching with chlorinated ferrous liquid, the formation of artistic patterns.
Spray Color method is in the screen printing after spraying color particles, constitute the surface of pear skin, the formation of artistic patterns.
