(Because different steel mills have different processes, different processes lead to different costs, so they are not used as actual production costs of steel mills, only for reference and estimation)  

1.Low-nickel iron production of cold-rolled stainless steel =

Low nickel iron price *0.6/1.8*6.8+Pure nickel plate average price *0.015+ (low nickel iron price - low nickel iron price *0.6) *0.8+ high carbon ferrochrome bid price *2/100*18.5+ other Cost { steelmaking cost (redreded by red) + rolling cost + pickling cost + cutting head cutting cost + coke coking coal cost (floating) + refractory cost (floating) + other raw material cost + packaging cost + material loss cost } .  

2, high nickel iron production of cold rolled stainless steel costs =

High nickel iron bid price *8.05+ (high nickel iron bid price *8.05/0.8-high nickel iron bid price *8.05) *0.8+ high carbon ferrochrome bid price *2/100*18.5+ other cost { steelmaking cost (Red has been subtracted) + Rolling cost + pickling cost + cutting head cutting cost + coke coking coal cost (floating) + refractory cost (floating) + other raw material cost + packaging cost + material loss cost}. Calculation of stainless steel cost (high ratio of nickel to iron, low proportion of pure nickel)
