321 stainless steel coils is 18/8 austenitic stainless steel stabilized with titanium, 321 is intended for applications in the temperature range up to approximately 900°C and combines high strength, resistance to oxidation peeling and subsequent phase stability against aqueous corrosion. The material is not easy to process, and the chips are not easy to cut off and break. Under the selected corrosion conditions, the sample of 321 stainless steel coil has no obvious change in surface finish within 960h, the corrosion rate is less than 0.04g/m2. The 321H has high thermal strength, especially suitable for high temperature structure applications.
