Special stamping techniques
Can you deep draw ultra-hard or high-strength materials?
Answer
When to Select Progressive Die Stamping Part features are flat or slightly contoured Depth is less than 1.5 times the diameter Multiple features (piercing, bending, embossing) are required Production volume is very high Tooling cost must be minimized General Design Principles Material Selection: For deep drawing, you need materials with high anisotropy (r-value above 1.6) and elongation over 30%. Low yield-to-tensile strength ratios—below 0.65—give you the best formability and reduce cracking risk. Punch and Die Radii: In deep draw tooling, the die entry radius should be 4 to 10 times the material thickness. This controls material flow into the cavity and minimizes stress concentration at the bend line.
Why this page is short
Published material currently supports only part of this question. The page states what is known and stops, rather than filling the gap with a plausible number. The missing detail sits on the review board waiting for an engineer.

- Carbon Steel Stamping & Deep Drawing | BalfordCan a part be specified in high carbon steel and still be deep drawn? + Usually not as a deep draw. High carbon grades such as 65Mn or SAE 1060 are chosen for spring behaviour after hardening, and in that state they blank and lightly form rather than flow. If the geometry genuinely needs a deep draw...
- Carbon Steel Stamping & Deep Drawing | BalfordTwo consequences for a drawing. First, the anneal: medium and high carbon parts that need more than light forming normally require an intermediate anneal between stages, and bulk heat treatment is carried out by qualified partners rather than in our own plant — so it is declared on the quote a...

- Aluminium Grades For Deep Drawing: 1050, 1100, 3003, 5052For deep drawing, the workhorse is 3003 in the annealed O temper, a manganese bearing alloy with good ductility and enough strength to be useful. Where the part is not structural and the draw is severe, the pure grades 1050 and 1100 are even more formable and correspondingly softer. The magnesium al...
What an engineer still needs from you
- material and material condition (grade, temper)
- material thickness, plus the key diameter, height and wall thickness
- tolerances, burr direction and the visual acceptance standard
- annual volume - it decides whether tooling is single-hit, progressive or transfer
- surface finish, and any secondary machining, annealing or plating
Need a DFM feasibility assessment for your project?
Send the engineering drawing (STEP or PDF) with the material grade, thickness and annual volume. Balford engineers then check it against the process window - draw ratio, wall thickness, tolerances, blank and tooling route - and come back with what is feasible and what is not. An answer on this page cannot replace that review.
