Grade and condition limits

E1 for DC53 requires hardened and tempered condition, length and width each ≤600 mm, and thickness 10–200 mm. The three dimensional tolerances are ±0.02 mm; parallelism is 0.02 mm per 100 mm. Larger sizes, annealed material or additional requirements need separate 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

  • Identify the actual delivery condition and hardness requirement for the DC53 blank.
  • For E1, confirm the hardened-and-tempered condition and final dimensions before assigning tolerances.
  • If the blank is part of a larger tooling package, mark the matching dimensions and inspection datums that matter to your assembly.

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.

Typical production: 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.

DC53 Tool Steel Plate Questions

When is ±0.02 mm available for DC53 ground blocks?

The published E1 option applies to hardened and tempered DC53, length and width each ≤600 mm and thickness 10–200 mm. Additional geometric or surface requirements need drawing-specific agreement.

Does the DC53 plate quote include every later tooling operation?

The quote identifies the plate faces, dimensions, material condition and specified work. Later cavities, holes, allowances and other tooling operations must be listed if you want them included.

What should accompany a DC53 precision plate RFQ?

Provide the drawing revision, finished dimensions, quantity, material condition, finishing route, acceptance datums, required MTC/hardness/dimensional documents and delivery destination.
