Electro slag remelting:
The largest ingot can reach 3 tons in Senda company .The ingot obtained by this remelting/refining process is very homogeneous and free of internal defects . The segregation of the ingot (called macro-segregations ) are substantially eliminated and the segregations of crystals (called macro-segregations ) are significantly reduced .
The ESR remelted material improve following mechanical characteristics :
Improved toughness due to increased homogeneity and isotropy
Improved creep resistance properties
Best fatigue strength and tenacity properties as well as outstanding tensile strength
Improved purity
