Published typical values for 1045. Other grades in the family differ — the certificate supplied with your order carries the actual heat-lot figures.
Rust. Bare steel flash-rusts within hours in a humid container, so parts are oiled or passivated before packing unless you specify otherwise.
Machining SGCC Steel with CNC Saw Cutting
SGCC Steel behaves predictably under CNC Saw Cutting once parameters are dialled in: machinability is good to excellent depending on carbon content; free-machining grades cut cleanly, and we tune the operation accordingly.
We hold reference parameters for this grade, so repeat orders of SGCC Steel run consistently from one batch to the next.
Achievable Tolerances for CNC Saw Cutting SGCC Steel
| Feature | Standard | Precision |
|---|---|---|
| Bend angle | ±1.0° | ±0.5° |
| Flange length | ±0.30 mm | ±0.15 mm |
| Hole-to-bend distance | ±0.30 mm | ±0.15 mm |
| Minimum inside radius | 1.0 × thickness | 0.8 × thickness |
| Minimum flange height | 4 × thickness + radius | 3 × thickness + radius |
| Bend-to-bend spacing | ±0.30 mm | ±0.15 mm |
| Sheet thickness range | 0.5–8.0 mm | 0.5–4.0 mm |
Standard is what a normal quotation assumes. Precision is available on nominated features and is priced separately, because it needs extra setups, in-process gauging and CMM verification. Call out only the features that need it — blanket-tightening a drawing is the single most common reason a quote comes back expensive.
Design Tips for CNC Saw Cutting SGCC Steel
We are happy to suggest design tweaks that improve manufacturability. Consistent bend radii, adequate flange lengths and grain-direction awareness reduce cracking and springback in formed SGCC Steel. If you send your model early, we will return practical DFM feedback before you commit to production.
Why SGCC Steel?
SGCC Steel is chosen when a part needs what this grade offers — it is strong, economical and widely available. We confirm the grade and any temper or heat-treat condition with you before machining.
CNC Saw Cutting Tolerances & Surface Finish
Formed SGCC Steel holds bend angles to about ±0.5° and consistent flange dimensions, with bend allowance compensated for the material and thickness.
Final tolerances are governed by the material's behaviour, wall thickness and overall stiffness. We give honest DFM feedback if a callout would be costly or better achieved another way.
CNC Saw Cutting Quality & Inspection
We control quality throughout the process, not just at the end. In-process checks plus final inspection — including CMM where specified — keep every SGCC Steel part to print. Inspection reports, material certificates and first-article documentation can be supplied on request.
Secondary Operations & Finishing
Finished SGCC Steel parts can move straight into secondary operations under one roof. Typical add-ons are deburring, passivation, anodising, plating, blasting, polishing and laser marking. We coordinate the whole chain so you receive complete, inspection-ready parts.
Applications of CNC Saw Cutting SGCC Steel
Customers order CNC Saw Cutting SGCC Steel components for everything from instrumentation to structural and functional assemblies. Whether you need a single prototype or recurring production volume, the same process discipline applies.
How to Order CNC Saw Cutting SGCC Steel
Getting a quote is simple. Share your model, the material grade, your quantity and target tolerances. You receive a clear quotation with lead time and honest manufacturability feedback.
Finishing Options for SGCC Steel
| Finish | Thickness / effect | Why it gets specified |
|---|---|---|
| Black oxide | 1–2 µm | Mild corrosion resistance, no dimensional change |
| Zinc plate + clear/yellow | 5–12 µm | ASTM B633, general corrosion protection |
| Nickel plate (electroless) | 10–25 µm | Uniform in bores, 500 HV after bake |
| Phosphate | 5–10 µm | Paint key, mild lubricity |
| Powder coat | 60–120 µm | RAL colours |
| Deburr / edge break | 0.05–0.3 mm | All parts unless the drawing says otherwise |
| Bead blast | Ra 1.6–3.2 µm | Uniform matt finish, hides tool marks |
| Laser marking | — | Part number, lot code, data matrix |

What We Need to Quote CNC Saw Cutting SGCC Steel
- GeometrySTEP or IGES for the 3D model, plus a PDF drawing if you have tolerance callouts. A dimensioned sketch is enough to start.
- MaterialThe exact SGCC Steel grade and condition — temper, heat-treat state or hardness. If you are not sure, tell us the function and we will suggest one.
- QuantityPrototype count and the expected annual volume. Both change how the part is made and therefore what it costs.
- TolerancesWhich features are critical. Everything else runs to our standard tolerance, which is what keeps the price sensible.
- FinishSurface treatment, cosmetic requirements, and any faces that must be masked.
- DocumentsWhether you need a material certificate, dimensional report, FAIR or PPAP with the shipment.
Missing something from the list is not a problem — send what you have. We will come back with the specific questions rather than a generic form.

Request a QuoteFrequently Asked Questions
What material thickness or size range suits CNC Saw Cutting SGCC Steel?
We form SGCC Steel sheet and plate to your developed flat pattern and bend sequence.
How clean are the edges produced by CNC Saw Cutting on SGCC Steel?
Machined SGCC Steel edges are clean and to specification; edge-break or deburring is added when your drawing calls for it.
Does CNC Saw Cutting SGCC Steel require dedicated tooling?
Most SGCC Steel forming work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
What is the typical lead time and minimum order for CNC Saw Cutting SGCC Steel?
CNC Saw Cutting prototypes for SGCC 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.
What tolerances can you hold for CNC Saw Cutting SGCC Steel?
Achievable tolerances for SGCC Steel forming depend on the alloy, geometry and feature size. We hold tight, repeatable tolerances appropriate to the feature and material. Exact figures are confirmed against your drawing callouts.
