Not round

Product advice on steels to be used for:
Important specification
  • Weldability
  • Flanging ability
  • Corrosion resistance
Recommendation

Non-round, 3P cans require: excellent axial resistance for safe transportation; panelling resistance to withstand retorting pressure constraints; and dent resistance.

For efficient production, grades exhibiting high-speed welding and flanging performance should be selected.

The smaller curvature radius of rectangular cans makes flanging more difficult. Softer grades, typically with a yield strength of ≤ 415 MPa, are recommended.

Metallic coating: Tin coating only (ECCS not weldable).

Corrosion resistance: Tin coating must be selected based on the aggressiveness of the food.
