Fully Spheroidized M2 Annealed Tool Steel Fresh From Furnace With Microstructure Report Included - China

M2 annealed tool steel is the delivery condition that every downstream fabricator needs before machining a high speed steel into a finished tool.

This listing explains exactly what you should expect when you order M2 in the fully annealed state, and how our furnace practice guarantees repeatable microstructure batch after batch.

What fully annealed M2 annealed tool steel means in practice:

- Hardness range 207 to 255 HB, hardness difference across the section kept below 20 HB

- Carbide structure fully spheroidized, no fine lamellar carbide remnants that would accelerate tool wear during machining

- Grain size uniform after recrystallization annealing

- Decarburization depth controlled and removed by machining before shipment Our annealing furnace practice for M2 annealed tool steel:

1 - Slow heating to 850°C with soak time calculated per thickness (1 hour per 25mm rule)

2 - Hold at 850-880°C for complete spheroidization of secondary carbides

3 - Controlled furnace cooling at less than 30°C per hour down to 550°C, then air cool

4 - Hardness sampling from head, middle and tail of each annealing batch

5 - Metallographic confirmation on representative samples with photomicrograph archive per heat number Machinability data you can use for process planning:

- Turning with coated carbide inserts at 70-110 m/min surface speed

- Drilling with cobalt HSS or solid carbide tools with generous point clearance

- Sawing on band saws at feeds above 0.06 mm/tooth to avoid work hardening the surface

- Wire cutting directly from annealed blocks for complex punch profiles Available forms of M2 annealed tool steel from stock:

- Round bar 6-300mm diameter, forged or rolled

- Flat bar 3-100mm thickness

- Plate and block up to 610mm wide, rough milled all faces

- Strip and small drawn bar for automatic lathe feed Quality paperwork included per shipment:

- EN 10204 3.1 certificate with heat chemistry

- Annealed hardness certificate with sampling positions

- Spheroidization microstructure photomicrograph

- UT report per SEP 1921 on request Because every later heat treatment result depends on how well the steel was annealed first, buying verified M2 annealed tool steel protects your hardening cycle, your grinding allowance and ultimately your tool life.

Batch samples of 20-30kg can be cut for prospective partners who want to validate our annealing quality against their current supplier.
