Short answer: Available tolerances depend on the grade, thickness, width, product standard, temper and processing route. Buyers should name the governing standard and identify critical limits rather than asking for an undefined ‘tight tolerance.’
This guide is written for stainless steel buyers, sourcing teams, engineers and product manufacturers. The purpose is not to declare one universal winner, but to turn a broad material question into a specification that a mill or service center can quote, process and inspect consistently.
Quick Comparison
| Option | Key point | Typical use or decision |
|---|---|---|
| Thickness | Measured at defined positions | Affects weight, stiffness and forming |
| Slit width | Specified nominal plus/minus limit | Affects guides, tooling and part width |
| Camber | Sideways deviation over a stated length | Critical for roll forming and narrow strip |
| Burr | Edge projection after slitting | Affects safety, tooling and welding |
| Flatness | Deviation from a reference plane | Important for laser cutting and panels |
The table is a starting point. Actual performance depends on the governing standard, delivered condition, dimensions, surface finish, fabrication route and service environment. Commercial names should never replace a complete purchase specification.
What Buyers Should Evaluate
- Define measurement method and sampling frequency.
- Separate mill capability from service-center slitting capability.
- Use capability trials for unusually narrow or thin strip.
For production orders, share the end use rather than requesting a grade or finish in isolation. A supplier can then review corrosion exposure, forming severity, welding, visual requirements and packing before material is cut. This early review is usually less expensive than correcting a rejected shipment or unstable production trial.
Common Purchasing Mistakes
- Combining several standards without defining precedence
- Specifying zero burr after slitting without secondary edge treatment
- Demanding a tolerance tighter than the process needs
These mistakes are avoidable when drawings, approved samples, inspection methods and certificate requirements are agreed before production. For visual products, retain a signed master sample. For functional dimensions, define where and how measurements will be taken.
Recommended RFQ Wording
State nominal size, plus/minus limits, measurement method, edge condition, camber length, burr maximum, coil ID and sampling plan.
Also include order quantity, acceptable quantity variation, destination, required delivery date and whether partial shipments are allowed. If a requirement is critical, make it measurable and place it on the purchase order rather than only in an email conversation.
How Still Steel Supports the Project
Still Steel supplies stainless steel coil, strip and sheet and provides slitting, cut-to-length, brushing, polishing and protective-film services. We can compare available mill material with your drawing, prepare trial quantities and preserve heat-number traceability through service-center processing.
Send the grade, dimensions, annual volume and application to vip@still-steel.com, or discuss the requirement on WhatsApp.
Frequently Asked Questions
Can every thickness be supplied to the same tolerance?
No. Capability changes with thickness, width, grade, temper and equipment.
What is camber?
Camber is the lateral curvature of strip along its length and can cause tracking problems.
Can slit strip have zero burr?
Slitting creates an edge profile. Very low or rounded burr may require optimized tooling or secondary edge conditioning.
