VT machining offers CNC Broaching for A36 Steel (ASTM A36 / ~S275JR / Q235B), typically supplied hot-rolled. General structural plate; cheap and weldable, mill scale must be removed.
CNC Broaching Notes for A36 Steel
A36 Steel broaches well for keyways, splines and internal forms; we set the tooth rise per tooth for this grade.
For estimating, a 100 × 100 × 10 mm block of A36 Steel weighs about 0.79 kg.

Can VT machining make custom A36 Steel parts to my drawing?
Yes. A36 Steel machining 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.
What tolerances can you hold for CNC Broaching A36 Steel?
Achievable tolerances for A36 Steel machining depend on the alloy, geometry and feature size. Milling holds positional and dimensional tolerances to around ±0.01 mm, tighter with precision setups. Exact figures are confirmed against your drawing callouts.
Why is A36 Steel a good choice for CNC Broaching?
A36 Steel is strong, economical and widely available, which makes it well suited to CNC Broaching. We tune the process to the alloy so the finished A36 Steel machining part meets your dimensional and functional requirements.
What material thickness or size range suits CNC Broaching A36 Steel?
We machine A36 Steel across a broad size range; share your part envelope for confirmation.
What surface finish is achievable on A36 Steel with CNC Broaching?
Surface finish on A36 Steel is controlled to your specification; we confirm the achievable Ra against your callout.
What is the typical lead time and minimum order for CNC Broaching A36 Steel?
CNC Broaching prototypes for A36 Steel can be produced quickly and scaled to series production. Send your drawing and quantity and we will advise lead time and any minimum order.
