Annealed M2 Flat Bar In Standard Thicknesses For Die Blocks And Broach Manufacturing - China

M2 flat bar is the starting form chosen by die makers who want to save machining time on rectangular tool parts such as die inserts, broach bodies, shear blades, gauge plates and template blocks.

Compared with buying round bar and milling it square, ordering the correct flat section from stock can cut your raw material cost and machine hours significantly.

Stock dimensions of our M2 flat bar:

- Thickness: 3, 4, 5, 6, 8, 10, 12, 15, 20, 25, 30, 40, 50, 60, 80, 100 mm

- Width: 20 to 300 mm standard combinations; special sections by forging

- Length: 2 to 4 meters, or cut-to-size blanks with saw tolerances of +3/0 mm

- Surface: hot rolled annealed (black), rough machined bright, or precision ground on two opposite faces Tolerances you can choose when ordering M2 flat bar:

- Hot rolled annealed: thickness +1%, width +2%, suitable for customers who machine all faces

- Rough machined: thickness and width to ISO h11, minimum machining allowance left for finishing

- Precision ground: thickness to h9 with parallelism 0.02mm, ready for direct wire cutting or hardening Quality points specific to flat products:

1 - Flatness control.

Rolled flat bar tends to banana during annealing, so we straighten every bar before dispatch and guarantee straightness within 2mm per meter.

2 - Carbide banding direction.

For broaches and shear blades, carbide bands should run parallel to the working edge; tell us the working direction and we will select the bar accordingly.

3 - No rolled-in scale pockets on bright surfaces, verified by magnetic particle inspection on request.

4 - Full traceability: heat number stamped on each bar and EN 10204 3.1 certificate with actual chemistry and hardness.

Annealed hardness is max 255 HB so the bar can be machined, drilled and tapped before your hardening cycle.

After vacuum hardening from 1200-1220°C and triple tempering at 560°C, working hardness reaches 62-65 HRC; linear size change is about +0.15-0.20%, which should be included in your pre-hardening machining allowance.

We export M2 flat bar weekly to European tool factories with sea-freight-proof wooden packing, and urgent partial orders can be collected from our Dongguan warehouse same week.
