The Mill mainly works with grades of low-alloyed steel 20GL, 20GFL, 30GSLB according to GOST (Ukrainian and CIS standards)
Also it uses other materials:
Grades of carbon steel from 15L to 30L according to GOST
The volume of a one-short order must be divisible by 13-18 ton; weight of casting is from 1 to 560 kg
Grades of carbon steel 35L, 40L, 45L according to GOST;
Grades of grey iron from SCh10 to SCh35 according to GOST;
Grade of ductile iron VCh450 according to GOST;
Grade of low-alloyed heat-resistant cast iron ChH1.
The total capacity of castings from the items 2)-5) is 500 ton per year; weight of castings is from 0.5 to 200 kg.
