Purpose
- Ni-Co-Mo-Ti solid TIG rod (Werkstoff 1.6356), precipitation-hardening maraging steel, Rm 980 MPa.
- Wear-resistant surfacing of stamping, drawing and bending tools; reinforcing cutting edges.
Why it works
Unlike the rest of the TLS line (medium-high carbon plus Cr/Mo/W forming carbides), this alloy is an age-hardenable maraging steel: near-zero carbon (0.005%) on a Ni-Co-Mo-Ti base that hardens through intermetallic precipitation during a subsequent heat treatment, not through carbides — the result is a high-strength deposit (Rm 980 MPa) with good weldability onto high-strength steels.
Fields of application
- Wear-resistant surfacing of stamping, drawing and bending tools.
- Reinforcing cutting edges on dies and cold shears; joining high-strength steels.

Advantages
- Highest mechanical strength in the TLS line (Rm 980 MPa) via precipitation hardening.
- Good weldability onto high-strength steels — unlike other high-hardness alloys, it doesn't rely on brittle carbides.
Limitations
- Final strength depends on a subsequent age-hardening heat treatment — as-welded, it doesn't reach its full potential.
