Dura® is offered with different carbon contents and flexible hardness ranges, depending on rolling applications. These rolls are particularly suited for roughing stands where neck strength is more important than wear resistance.

Description
Heat treated Cr-Ni-Mo alloyed pearlitic / bainitic cast steel

APPLICATION Roughing, Intermediate and Finishing stands for Medium Section and Heavy Section mills Roughing, Intermediate and Finishing stands for Medium Section and Heavy Section mills Roughing, Intermediate and Finishing stands for Medium Section and Heavy Section mills Universal Beam and Rail mills
C% 1.4 - 2.2
Si% 0.3 - 0.6
Mn% 0.5 - 1.5
Ni% 0.5 - 3
Cr% + Mo% Up to 3.5

*The hardness adjustment is obtained during a complex heat treatment process.
For production, we need a range of 5 ShC which needs to be specified in the roll order.

Our technical team can help to determine the most suitable grade, degree of hardness and manufacturing method to meet with individual mill conditions and specifications.
