Applications

Typical Applications

TGX6 applications listed in the PSS catalog.

Stamping and cutting

  • High-volume stamping dies and progressive dies
  • Fine blanking tooling
  • Trimming and coining tooling
  • Precision slitting knives

Forming

  • Cold forming dies under impact loading
  • Deep drawing and ironing dies
  • Thread rolling dies (long-run)

Other

  • Powder metallurgy compacting dies
  • Long-run production tooling that requires chipping resistance

Assessing the fit for your die

The right stamping die material depends on the material being stamped, the production volume and the current condition of the die. Include this information in your inquiry so the PSS team can assess your requirements.

Technical data

TGX6 Technical Data

Material Properties

  • High-chromium platform

    Developed by Tiangong International from a high-chromium cold work tool steel platform (SKD11/2379 family) to address the main limitations of conventional SKD11: relatively low toughness and susceptibility to edge chipping under high impact loads.

  • Carbides and toughness

    A finer, more uniform carbide distribution than standard SKD11/2379, with improved impact toughness at full hardness thanks to Tiangong’s carbide refinement process.

  • Hardness and stability

    Working hardness comparable to standard SKD11/2379, with compressive strength and abrasion resistance at the level expected of this steel class, and good dimensional stability in heat treatment.

  • Availability

    PSS supplies TGX6 plate with full Tiangong documentation.

Heat Treatment

  1. Annealing

    Follow the Tiangong technical datasheet supplied with the material.

  2. Hardening

    Consult the Tiangong datasheet. Parameters are similar to the SKD11 family but optimised for TGX6. Contact the PSS technical team.

  3. Tempering

    Double tempering is recommended per the Tiangong datasheet. Target hardness 58–62 HRC.

FAQ

Questions about TGX6

What is TGX6?

TGX6 is a cold work tool steel grade developed by Tiangong International. It is one of the Tiangong Special Grades featured by PSS, with a focus on stamping die applications.

In what form is TGX6 available?

TGX6 is available as plate. Tell us the thickness, width, length and quantity you need, and the PSS team will confirm the available sizes.

Is TGX6 the same as SKD11/2379?

No. TGX6 is a Tiangong grade in its own right, not another name for SKD11/2379. If your die currently uses SKD11 or another grade, mention that grade and the condition of the die in your inquiry.

How can I get the TGX6 datasheet?

Mention your datasheet or technical data requirements in the notes field when you send your inquiry. The PSS team will confirm which documents are available.

Can TGX6 be cut or milled to size?

Yes. PSS offers precision cutting with a band saw up to 1,000 mm wide and a standard tolerance of ±1 mm, and CNC milling with a standard tolerance of ±0.1 mm. You can request material and processing in a single inquiry.

Does TGX6 come with a Mill Certificate?

Every order comes with a Mill Certificate from the mill of origin, or on request. Let us know your documentation requirements in your inquiry.
