Notes on the comparability of impression method and tensile test:

Three (austenitic stainless steels and five aluminum) tests were averaged by the indentation method and compared to the result of a tensile test. A point in the diagram corresponds to the result of the impression procedure (x-axis) and the tensile test (y-axis)

The aluminum materials were divided into two groups for verification: cast and wrought alloys. The following lists the materials that have been tested, inter alia, for verification with the impression method.

Cast alloys:

Die-cast aluminum-silicon

  • AC-43500EN
  • AC-46000

Smelting alloys:

EN-AW-5082
EN-AW-5083
EN-AW-5754
EN-AW-6060
EN-AW-6061
EN-AW-6063
EN-AW-6082

Cast alloys produced in fine, sand or chill casting can not be tested at the current state (04.2019). Likewise, no die-cast alloys made of aluminum-magnesium and no 2,000 and 7,000 wrought alloys.

Korrelation Aluminium

 

In the verification of nickel materials for the indentation process, we tested, among other things, samples of the following materials and compared them to the tensile test:

  • 2.4360
  • 2.4668
  • 2.4816
  • 2.4819
  • 2.4856
  • 2.4858

Korrelation Nickel

 

In the verification of steel materials for the indentation process, among other things, we tested samples from the following materials and compared them to the tensile test:

  • Mild steel (heat-resistant, unalloyed and fine-grained structural steel)
  • Hardened steel
  • Working steel (rolling bearing, spring steel)
  • Tempering steel
  • Cast steel
  • Cutting steel
  • Cold forming
  • Fine-grain cold pressed steel
  • High alloy martensitic steel
  • High-alloy austenitic-ferritic steel

Heat-resistant steel and high-alloyed austenitic steel can not be tested at the current state (05.2019).

For structural steel, the comparative yield strength RI0.2 corresponds to the lower yield strength ReL from the tensile test.

The verification distinguishes between high-alloyed and low-alloyed steels (see bullet points 1-8).
