Chromoly Steel process
Chromium alloy billet can be made by smelting or powder metallurgy. Because of its

high vapor pressure, chromium needs inert gas protection during smelting. High quality

ingot can be obtained by smelting electrolytic chromium refined by chromium iodide or

hydrogen and adding alloying elements. Dispersion - strengthened alloys can be obtained

by adding dispersion - phase compounds directly to chromium by powder metallurgy.

Plastic processing can be extruded, and then forged or rolled, the use of mild steel cladding

to facilitate deformation, after processing with pickling removal of steel sleeve. Some

chromium alloy targets can also be formed by hot isostatic pressing
