A2 Precision Tool Steel Plates

A2 precision tool steel plates are supplied as a drawing-defined machining package for further tooling work. State whether the required dimensions apply before or after any heat treatment, identify the delivery condition and mark the remaining machining allowance. Material, finished size and inspection are confirmed in the quotation.

Grade and condition limits

A2 is outside the published E1 grade list. The listed G2 and M6 options retain their own tolerances. Send a different grinding scope or tighter requirement for separate technical review.

Grade designations are listed separately; no automatic equivalence or substitution is assumed. Per-100-mm parallelism does not define whole-plate flatness or surface roughness.

Drawing and Quotation Checklist

  • Distinguish pre-treatment machining dimensions from final acceptance dimensions after any specified heat-treatment operation.
  • Mark finished length, width and thickness, reference faces, tolerances, datums and any whole-plate geometric requirements.
  • Specify quantity, required material/hardness/dimensional records, any requested UT scope and delivery destination.

Include quantity, drawing revision, required inspection documents and delivery destination. Single-piece and small-batch inquiries are accepted.

Inspection and Production Planning

MTC material documentation, hardness and dimensional inspection reports can be requested. UT reports are available on request with an agreed scope. Regular plate sizes range from 100×100×20 to 800×600×300 mm; maximum processing size is 1200×800×400 mm, subject to grade, condition and finish review. This maximum does not carry the E1 tolerance.

Production schedule: 3–7 working days. Working days exclude weekends and statutory public holidays in China. The clock starts on the next working day after formal PO receipt, final drawing/specification approval and applicable deposit receipt are all completed. Transport time is separate.

A2 Tool Steel Plate Questions

Which finishing options are listed for A2 precision plates?

Two-side grinding with four-side milling uses ±0.05 mm for thickness and ±0.10 mm for length/width, with parallelism of 0.04 mm per 100 mm between the ground faces. Six-side milling uses ±0.10 mm in all three dimensions and parallelism of 0.08 mm per 100 mm. Size, condition and drawing review still apply.

Can A2 be ordered with E1 six-side grinding at ±0.02 mm?

A2 is outside the published E1 grade/condition list. A different grinding or tolerance request can be submitted for separate technical review; the standard E1 tolerance is not automatically assigned.

Which delivery condition should be specified for A2 plates?

State the required condition and any hardness acceptance requirement on the drawing or inquiry. Material sourcing, processing route and the actual supplied condition are confirmed in the quotation; no generic hardness range is assumed.

Should an A2 precision plate be ordered before or after heat treatment?

State the required delivery condition and when the drawing dimensions must be accepted. If further heat treatment is planned, agree the machining allowance and the responsibility for final grinding. A grade label alone does not settle this sequence.
