Datum 304 HTA
• A precision 304 Stainless thin foil for applications where flatness and uniform gauge are critical.
• Exceptional shape control when laser cutting and etching.
• Wide range of dimensions and rapid delivery options.
The TA Advantage
Wide Range of Dimensions
Tension annealing (TA) is a specialized process to relieve internal
stress while the strip is under tension creating the mechanical
properties of a hard temper without the rolling stresses typically
induced into a material to produce these properties. This results
in a hard material that can be laser cut and etched without shape
deformation.
Gauge
• 0.02mm – 0.50mm (0.8mil – 20mil)
• Includes intermediate sizes such as 0.03mm, 0.04mm,
0.06mm, 0.07mm, 0.09mm, 0.11mm, 0.12mm
Rapid Turnaround
