This information is pertaining to Cond B or Cond S materials, or higher strengths. These strengths are also sometimes referred to as HPA Strength Levels 1, 2, 3, 4 or 5 which cover a broad range of properties for the Nitronic grades. These strength levels developed by High Performance Alloys help to define the product properties delivered to customers. These strength levels help to convey the minimum properties that should be expected.
