Mechanical properties of cr13al4 alloy in annealed state at room temperature:

Alloy stateTensile strength < br clear = "all" / > σ B (MPA)Elongation < br clear = "all" / > a5%
Cr13Al4≥580≥12

This alloy has the following properties:

15cr-4al has low aluminum and chromium content, high iron content, good oxidation resistance, thermal strength and high positive temperature coefficient below 800 ℃. Under normal temperature, it has high plasticity, cold stamping and general welding performance. After annealing, the structure of the alloy is ferrite, which is unstable in use. 475 ℃ is the brittleness temperature zone. After long-term heating, the grains are continuously coarse.

Metallographic structure of cr13al4:

Cr13al4 alloy is ferrite structure

Applications of cr13al4 include:

1. As a heating element, it is mainly used for heat treatment furnace with temperature below 750 ℃. However, it is not a common heating material

2. Heating wire for low gear electric heating pipe and low gear household electric heater

3. Resistance tape for resistance box
