Why choose ABRAFIL CrMo1?

1. Designed for CrMo steels

  • Ideal for welding steels containing around 1% chromium and 0.5% molybdenum.

  • Perfect compatibility with steels such as 13CrMo4-5, used in the manufacture of boilers, reactors, heat exchangers, etc.

2. Excellent heat resistance

  • ABRAFIL CrMo1 resists high temperatures and thermal oxidation.

  • It is often used for applications up to 550-600°C, or even higher with appropriate heat treatment.

3. Good creep behaviour

  • It maintains its mechanical properties over time, even under high-temperature loading, which is essential for pressurized installations.

4. Good weldability

  • Although it sometimes requires preheating (200-300°C) and heat treatment after welding, it remains relatively easy to MIG weld.

  • Provides good mechanical strength and resilience after treatment.
