Purpose
- Cr-Mo solid TIG rod (S Fe 3) for surfacing hot-work tool steel, 52-57 HRC hardness.
- Repair and new manufacture of tooling for service up to 500°C: continuous-casting rolls, hot-shear blades, die-casting molds, dies.
Why it works
Chromium (5%) and molybdenum (1.1%) on a medium-high carbon base (0.38%) produce a martensitic deposit with stable secondary hardness at elevated service temperature — this tempering resistance is what lets the die hold its hardness through repeated heating cycles in service, instead of softening after the first few hours of use.
Fields of application
- Continuous-casting rolls, hot-shear blades, die-casting molds, dies.
- Repair and new manufacture of hot-work tooling for service up to 500°C.

Advantages
- Stable secondary hardness — resists tempering through repeated in-service heating cycles.
- Continuous service up to 500°C.
Limitations
- Hardness (52-57 HRC) lower than TLS 2606 or TLS 3348 — not this datasheet's highest-wear-resistance option.
