Chemical Composition: C: 1.45-1.70%, Cr: 11.00-13.00%, Mo: 0.40-0.60%, V: 0.15-0.30%, Mn/Si ≤0.40%, P/S ≤0.030%
Pros: Hard (HRC 60-64), wear-resistant, not easy to deform; good for most punching tasks
Chemical Composition: C: 1.00-1.10%, Cr: 8.00-9.00%, Mo: 2.00-2.50%, V: 0.80-1.10%, Si: 0.80-1.10%, Mn: 0.30-0.60%, P ≤0.025%, S ≤0.010%
Pros: Tough, wear-resistant, stable; good for high-precision, heavy punching
Chemical Composition: C: 1.40-1.60%, Cr: 11.00-13.00%, Mo: 0.70-1.20%, V: 0.80-1.10%, Mn/Si ≤0.60%, P/S ≤0.030%
Pros: Very wear-resistant, stays sharp; good for cutting carbon steel, stainless steel, and profiles
Chemical Composition: C: 0.32-0.45%, Cr: 4.75-5.50%, Mo: 1.10-1.75%, V: 0.80-1.20%, Si: 0.80-1.20%, Mn: 0.20-0.50%, P/S ≤0.030%
Pros: Heat-resistant, tough; good for thick plates and hard materials
| Material | Applicable Working Conditions | Core Advantages | Core Disadvantages |
|---|---|---|---|
| 9CrSi | Light-duty machines, ≤5mm thin/soft materials, small-batch | Good toughness, low cost, entry-level general-purpose | Average wear resistance, not for thick/high-strength conditions |
| Cr12MoV | Small-medium tonnage, ≤10mm ordinary steel/profiles, regular batch | High cost-effectiveness, wear-resistant, small deformation, strong versatility | Average high-impact resistance, not for thick/hard materials |
| DC53 | Medium-heavy tonnage, thick plates, stainless steel & alloy profiles, high-volume production | Ultra-high wear resistance, excellent edge retention, great dimensional stability | Slightly lower toughness than H13, higher material & heat treatment cost |
Lubricate regularly: Use special lubricant on punches to reduce friction and heat; keeps Cr12MoV and DC53 in good shape.
Check blade clearance: Adjust the gap based on material thickness. Too wide = messy cuts; too tight = damaged D2/H13 blades.
Rotate blades: Many blades have 2-4 cutting edges. Flip them regularly for even wear and longer life.
Combined Punching & Shearing Blades: Made of D2 or H13; cuts steel plates, angle steel, etc. Sharp, wear-resistant, clean cuts.
Die Plate: Supports blades; keeps materials stable during cutting; fits different profiles.
Punching & Forming Molds: Made of Cr12MoV/DC53; for punching, bending, forming; precise and durable.
Punch: Core punching part; works with Cr12MoV/DC53 molds; precise, wear-resistant.
