Before Cutting

Date: 4 September 2026

Set the cutting process and the cutting layout so that no uncontrolled kerf or cracking risk arises.

• The cutting process is chosen by thickness and grade, with water jet preferred and oxy-fuel cutting used only with a defined preheating regime.

• For oxy-fuel cutting, preheating is to 170 plus/minus 30 degrees Celsius, with an additional four-hour hold planned in the thick range.

• The preheat zone covers the whole plate or a 100-millimetre strip on both sides of the kerf.

• Nesting is planned so that future bend lines lie transverse to the rolling direction.

• A machining allowance of 2 millimetres is planned on every thermally cut edge that will be joined or bent.

• Cut parts are wide enough to absorb the heat, because narrow offcut strips can crack.

• The enquiry specifies the cut quality, not just the cutting process.
