HSS Production - Haleforge Alloys

Electro-Slag Remelting Method of HSS Production

Electroslag Remelting (ESR) is a process of remelting a consumable electrode utilizing the heat generated by an electric current passing through a molten slag between the electrode and the solidifying ingot.

Advantages of Electroslag Remelting

Deep desulfurization.
Refining non-metallic inclusions.
Homogeneous Distribution of non-metallic inclusions
Fine Grain structure.
No Shrinkage defects.
Low macro-segregation.
Good surface quality.
Controllable process.

We have an in-house facility for production of HSS through ESR method.
We produce round bars starting from 65mm diameter up-to 400mm diameter in grades HSS M2 and HSS M35.
