5Route steps
A spring steel is primarily made by Heat Treatment. Heat treatment changes a metal's properties by controlled heating and cooling, hardening, tempering, annealing or case-hardening the part. Below is the full route to make a spring steel, the materials it suits, the tolerances to expect and the main design points. The route is free, from the finder.
Step by step
How a spring steel is made
The usual route, raw material to finished part. The amber step is where the spring steel gets its basic shape.
Make the part
Form and finish-machine the spring steel to size first.
Tooling None Tolerance ±0.125mm, to ±0.025mm Lead 1 to 10 days
Clean and mask
Clean the surface and mask the areas that must stay bare.
Heat Treatment
Apply the heat treatment to the spring steel.
Tooling n/a Tolerance can distort Lead days
Post-finish
Seal, cure or re-grind any surface that changed dimension.
Inspection
Check coating thickness, hardness or adhesion.

Cost
What a spring steel should cost
A secondary op costed per part/batch; raises hardness/strength. Budget for distortion and post-grinding.
PER-PART COST vs VOLUME
Per-part cost drops as volume spreads tooling and setup over more parts. The exact figures for a spring steel at your volume, in your currency, are in the dossier.

What does a spring steel cost?
It depends on size, tolerance and volume. As a rough ballpark it starts around $1.8 to 5.2 per part at 1 off and falls with quantity. The dossier gives should-cost at your exact volume and currency. A model estimate, not a quote.
What material is a spring steel made from?
Common choices are (hardenable steels).
What is the main process for a spring steel?
Heat Treatment. Setting hardness, strength and wear resistance on steels and alloys after shaping.
