Product
 YMPRESS
is a high strength steel plate with excellent
formability and weldability, produced by TMCP (Thermal Mechanical
Control Process)
Application
YMPRESS combines high strength with
excellent formability and weldability.
It is used in applications
such :
• Earth Moving Vehicles
• Large Cranes / Mobile Cranes
• Telescopic Booms
In these applications the high strength
of steel is used to save weight and
increase the load bearing capacity.
Fabrication
The low carbon equivalent of
Ympress makes it readily weldable
and permits the use of high welding
speeds. There is no need for pre-or
post-welding treatment.
Adjacent to the weld a narrow Heat
Affected Zone (HAZ) with a slightly
decreased hardness is produced,
however, with standard welding
techniques this has no practical
significance.
Tensile tests taken transverse to the
weld show the same tensile strength
as the parent material.
Stress relieving should be done in
temperature ranges of 980° - 1080° F.
Heating above this range reduces
strength and should be avoided.
