Steel and Iron Wear Resistant Castings

Steel and Iron Wear
Resistant Castings
PRESENTATION
Impact and abrasion resistant
steels and irons as well as alloy
steels specialists.
At the time of our foundry’s modernization, TRIMAN’s philosophy was to
equip itself in order to manufacture a wide range of parts that can weigh
from 4 kg up to 7 t, without almost any limitations. Our foundry is also capable to make a comprehensive range of alloys such as low alloy and carbon
steels but also high alloy ductile iron and high alloy cast irons.
• Our Research and Development Department,
located in Pamplona, uses Autocad® and Pro-Engineer® softwares. Moreover, our Mieres technical
department has at its disposal all the required CAD
licences as well as a skilled staff, and can deal with
any kind of drawing.
• Even if pattern making is subcontracted, we
dispose of qualified personnel and the appropriate
facilities, we can perform repairs and maintenance
tasks. We can also adapt the patterns if required.
