Hydro Turbine Castings are manufactured using electric-furnace plus AOD duplexing technique, which maintains the Ni4 series stainless steel content as per the commercial requirements. It also minimizes the impurity and gas content up to a minimum level ( [P,S] =0.04%,[N] =70ppm,[O] =40ppm). Castings manufactured using carbon lath martensite, are gi... |
