VT machining offers CNC Bending for P20 Mold Steel (UNS T51620 / 1.2311 / ~1.2738), typically supplied pre-hardened. Supplied pre-hardened, so molds are machined without heat treatment.
CNC Bending Notes for P20 Mold Steel
CNC Bending is rarely the right route for P20 Mold Steel: in its usual condition (Pre-hardened, ~28-32 HRC) it is not suited to this process. We normally recommend grinding, EDM or machining from bar instead — send the drawing and we will suggest the most economical method.
P20 Mold Steel bends to a tight inside radius (about 1× thickness) in this condition.
For estimating, a 100 × 100 × 10 mm block of P20 Mold Steel weighs about 0.79 kg.

What is CNC Bending P20 Mold Steel and how is it done?
CNC Bending P20 Mold Steel refers to cNC bending forms sheet metal to precise angles using a programmed press brake and back-gauge. Applied to P20 Mold Steel — mold-grade, polishable and hardenable — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
What material thickness or size range suits CNC Bending P20 Mold Steel?
We form P20 Mold Steel sheet and plate to your developed flat pattern and bend sequence.
Does CNC Bending P20 Mold Steel require dedicated tooling?
Most P20 Mold Steel forming work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
Why is P20 Mold Steel a good choice for CNC Bending?
P20 Mold Steel is mold-grade, polishable and hardenable, which makes it well suited to CNC Bending. We tune the process to the alloy so the finished P20 Mold Steel forming part meets your dimensional and functional requirements.
Can VT machining make custom P20 Mold Steel parts to my drawing?
Yes. P20 Mold Steel forming is made to order from your CAD/2D drawing. Share your geometry, material grade, tolerance and quantity and we will confirm feasibility, lead time and pricing.
How clean are the edges produced by CNC Bending on P20 Mold Steel?
Machined P20 Mold Steel edges are clean and to specification; edge-break or deburring is added when your drawing calls for it.
