321 stainless steel strip
Grade 321 is the grade of choice for applications in the temperature range of up to about 900°C, combining high strength, resistance to scaling and phase stability with resistance to subsequent aqueous corrosion.

321 stainless steel strip are used because they are not sensitive to intergranular corrosion after heating within the carbide precipitation range of 425-850°C. A limitation with 321 stainless steel is that titanium does not transfer well across a high temperature arc, so is not recommended as a welding consumable.
