Machining Guide of Alloy Steel High Pressure Steel Tube
Confirm Condition Before Cutting
Annealed tube machines easier than normalised & tempered stock
Step 1
Use Rigid Low-Speed Setup
Chrome Moly work-hardens fast – avoid dwell and light passes
Step 2
Select Carbide Tooling
Coated carbide inserts hold edge life on 5–9% Cr grades
Step 3
Pre-Heat Before Welding
Preheat T22 & T91 joints per WPS to avoid hydrogen cracking
Step 4
Post-Weld Heat Treat
PWHT restores toughness in the heat-affected zone
Step 5
Applications of Molybdenum Alloy Steel Welded Tubing
We are a reliable Alloy Steel Tube Supplier In India offering diverse applications.
