Machining Tips For X46 Pipe


TIP 01
Use Carbide-Tipped Tooling Holds an edge far longer against X46's higher tensile strength.
TIP 02
Control Cutting Speed & Feed Steady feeds limit heat buildup near the cut edge.
TIP 03
Flood Coolant During Bevelling Prevents work hardening at the cut face before welding.
TIP 04
Hold Bevel Angle to Spec Keep a consistent 30°±2.5° bevel for reliable weld penetration.
TIP 05
Avoid Interrupted Cuts Stopping mid-cut can create micro-hardened spots.
TIP 06
Verify Dimensions Post-Machining Check OD, wall thickness, and roundness right away.
