Personal protective equipment (PPE) must always be worn—this includes flame-resistant clothing, safety glasses, gloves, and other appropriate gear to ensure operator safety.
Material Temperature Requirements for High-Strength Steels
When cutting high-strength and wear-resistant steels, such as those produced by SSAB, the plate should be at room temperature unless otherwise specified in the material recommendations.
If the plates have been stored outdoors or in unheated areas where ambient temperatures drop significantly below room temperature, they must be preheated to room temperature before cutting—unless a higher preheat temperature is explicitly required.
If preheating is recommended, it is important to verify that the desired preheat temperature has been reached throughout the entire thickness of the plate. This can be done by measuring the temperature on the opposite side of the plate from where the heat is being applied.
Selecting the Correct Nozzle and Parameters
Prior to cutting, the correct cutting nozzle must be selected based on the material thickness. Corresponding cutting parameters—such as gas pressures and travel speed—should be set accordingly. For SSAB steels, the same nozzles and parameters used for mild steel can be applied unless otherwise stated.
Refer to the cutting equipment manufacturer’s guidelines for detailed recommendations regarding nozzle type and settings.
Depending on the equipment condition and setup, it may be necessary to fine-tune the parameters to achieve optimal cutting quality.
Proper preparation ensures safe and effective cutting, reduces the risk of defects, and helps maintain the mechanical properties of advanced steels.
