321 Stainless Steel Coil/Roll

JM Steel 321 Stainless Steel coil,It is used principally for applications involving welding or sustained elevated temperature operations.The high temperature uniform corrosion and electrochemical corrosion behavior of 321 stainless steel in uranyl nitrate solution with different concentrations and pH values were studied by weighing method and electrochemical method. The uniform corrosion test results show that under the selected corrosion conditions, the surface finish of 321 stainless steel sample has no obvious change within 960 h, and the corrosion rate is less than 0.04 g / m2 · h, which can resist corrosion in low acidity uranyl nitrate solution.

Standard: A240 480

Finishes: 2B Mill (dull), #4 Brushed,#8 Mirror,Hairline,No.1,Golden mirror other stainless steel color.
