Torch Cutting
We often must torch cut steel in the field to correct errors. Does torch cutting have an effect on the properties of steel? Is the type of steel a factor?

Answer
Thermal cutting is a normal operation of structural steel fabrication. The heat from the cutting operation generally will not be detrimental to the base material, although it can have an effect on the mechanical properties of heat-treated products such as high-strength bolts. If this is a concern, perhaps due to a bolted joint in close proximity to the cutting, for example, temperatures can be monitored.
