 High yield cold forming steel plate offers both strength and formability, with excellent surface quality, dimensional and geometrical accuracy and uniformity of properties.
Steel structures can be made lighter which means that the payload of machines and equipment can be increased and fuel consumption reduced.
Size Range:
Thicknesses: 3, 4, 5, 6, 8, 10,12mm
Widths: 1250mm & 1500mm
Lengths: Up to 14m
Welding
Despite its high strength, this steel is easier to weld than conventional lower yield grades. Good weldability means that preheating is not necessary under normal conditions. Surfaces must be both dry and clean before welding and welding materials must be of sufficiently low hydrogen content.
The weld material properties, including strength, can be of a lower strength than the steel being used provided that the weld is situated in a less stressed part of the structure.
Applications
- Agricultural equipment
- Axle parts
- Crane booms
- Defence applications
- Low weight piling
