We have all necessary know-how and facilities in-house to perform our scope of supply. Tasso is also ready to assist customers in terms of advice on choosing the most appropriate material and in logistics service. Choosing Tasso as your supplier means:
  • Specialised knowledge about continuous cast iron bars
  • High level of quality and service
  • Delivery on time 

Continuous casting

Tasso's continuous cast iron bars are made from recycled steel scrap and pig iron. Before casting, the material undergoes a careful preparation process of chemical analysis and adjustment to meet the requirements for the final cast iron bar.
At Tasso we are highly aware of running a secure process with a minimum of fluctuations to ensure uniformity in the cast iron bars. 

Heat Treatment

The properties of cast iron can be positively influenced by heat treatment. We use a number of heat treatment programmes to change or adjust the structure of the cast iron bars in order to achieve the desired properties.

Annealing heat treatment is carried out for the grades:

  • EN-GJS-400-15C
  • EN-GJS-400-18C-LT
  • EN-GJL-150C-A
Stress relieving or annealing heat treatment can be carried out for GJS- and GJL-grades upon request.
Customised heat treatment can be carried out according to agreement.


Tasso supplies both basic products in the form of cast iron bars and pre-machined components customised for optimal final processing.
Tasso has large processing capacity, so we can deliver according to customers' requirements and needs.
Please contact us for any inquiry related to machining of your components. We are effecient on both low and high volumes.
