Material description

The material data acquired through quality control testing are ideal for ascertaining how well our cold-strip products conform to established standards or customer specifications, as well as assessing production stability. However, we have found that, increasingly, it makes sense for our customers to have more advanced knowledge about how the material behavior of our products aid in the design of the components and processes in which those products will be used.

The BILSTEIN GROUP faced this challenge and is today, in cooperation with well-respected universities and research institutes, in the position to make the following data available:


Data for forming and crash simulations

  • Flow curves from tensile tests (L, Q, D)
  • Flow curves at higher deformation degrees
  • Forming limit curves


Case-hardened, tempered and spring steels

  • Time-temperature-transformation (TTT) diagrams (isothermal and continuously)
  • Austenitizing behavior
  • Tempering behavior


General physical properties

  • Thermal expansion coefficient
  • Specific heat capacity
  • Temperature conductivity
  • Thermal conductivity
