The equipment allows us to produce steel products using various heat treatments:
- soft annealed
- normalized
- annealed: isothermal, spheroidizing or stress relieving treatments
- hardened and tempered.

Steel Grades
ArcelorMittal Warszawa produces the following grades of steel for different applications:
- quality carbon steel
- low- and medium- alloy steel (case-hardening and through-hardening)
- carbon and alloy screw and nuts steel
- carbon and alloy chain steel
- killed and rimmed free cutting steel
- spring steel
- bearing steel
- micro alloys steel with Nb, V, B
- reinforcing steel.
Additionally, steel grades can be manufactured as:
- fine-grain steel
- steel with controlled sulphur content
- calcium treated steel
- steel with controlled hardenability to 50% of the band, so called “restricted hardenability”
- vacuum degassed, with hydrogen content below 2 ppm.
