 KIND OF PRODUCTS

Bloom with cross-section of 160-250mm and square steel billet of 50-160mm (with /without heat treatment);

The bars of  a diameter:

  • - 14-200mm with surface peeling (with/without heat treatment);
  • -14-75mm without surface peeling (with/without heat treatment);
  • -bars with special surface finishing, dia. 2-120mm (ground, polished, with/without heat treatment);
  • -square steel billet, cross section of  50-120mm, suitable for the following heat treatment , including upsetting, forging, hot forming with/without heat treatment.

  CHARACTERISTICS TO BE CONTROLLED (to be agreed when order is received):

  • -macrostructure
  • -ultrasonic test as per SEP 1921, class C/c
  • -mechanical properties on the heat treated samples or in the delivery condition
  • -non-metallic inclusions as per DIN 50602 (K4) or ASTM E45, (method A)
  • -grain size as per ASTM E112 or DIN 50601

  • -non-mixed test
  • -hardness

 NOTES:

  • the bars 14-200mm rd are to be produced with Ca, N, or S micro-alloying to improve the mechanical treatment;
  • the limited quantity of the bars can be delivered in the heat-treated condition (normalization, annealing,  high-temperature tempering) of the length up to 8,5 m
