Structures AS/NZS 1554.7 Structural steel welding of sheet steel structures 7-4 Boron alloyed The UHSS alloyed with boron is at the higher end of the advanced metals used in truck cab construction. Parts made from UHSS alloyed with boron should not be straightened or reformed. The steel panels are formed at extremely high temperatures and are prone to work hardening and cracking if damaged or deformed. Boron UHSS is weldable, and either the GMA (MIG) welding process or squeeze-type
