Stainless Steel Sheet Fabrication in China | Custom Stainless Steel Parts
Stainless steel sheet fabrication is an end-to-end process that is made to fit the exact tolerances your drawings specify. XTJ CNC has handled this work since 2005, serving custom stainless steel parts to OEM engineers and procurement teams across the aerospace, automotive, medical, and electronics industries.
We work from 0.5 mm sheet stock through 25 mm plate, across grades from 201 and 304 through 316L, 310S, and 904L. Single prototypes ship in three to five days. Production batches scale without switching suppliers or renegotiating terms. If your specs are clear, we can quote within 24 hours.
Custom Stainless Steel Parts Built to Spec, Delivered in Days
We manufacture custom stainless steel fabricated parts matched exactly to your specifications. Our 120+ advanced machines handle every step from fiber laser cutting and CNC bending to Tungsten Inert Gas (TIG) welding, surface finishing, and Coordinate Measuring Machine (CMM) inspection. Nothing ships without documented dimensional verification against your drawing tolerances.
Our sheet metal fabrication service covers stainless steel sheet thicknesses from 0.5 mm to 25 mm across a full grade range — from workhorse 304 through corrosion-resistant 316L, high-temperature 310S, and super-austenitic 904L.
Grade selection drives cost, corrosion performance, weldability, and formability. The table below covers every grade we stock and fabricate regularly. If your application requires something outside this list, our engineering team will recommend the closest alternative.
| Grade | Type | Key Properties | Common Applications | Thickness Range |
|---|---|---|---|---|
| 201 | Austenitic | Lower cost, moderate corrosion resistance | Enclosures, interior trim, signage | 0.5–4 mm |
| 301 | Austenitic | Work-hardens well; high strength after forming | Springs, rail components, appliance housings | 0.5–3 mm |
| 304 / 304L | Austenitic | Excellent corrosion resistance, highly weldable | Food equipment, medical frames, general fabrication | 0.5–12 mm |
| 316 / 316L | Austenitic | Molybdenum addition for chloride resistance | Marine, pharmaceutical, chemical processing | 0.5–10 mm |
| 310S | Austenitic | High-temperature oxidation resistance to ~1,100°C | Furnace parts, heat exchangers | 1–6 mm |
| 904L | Super austenitic | High Ni/Mo; resists concentrated acids and pitting | Offshore equipment, aggressive chemical environments | 1–8 mm |
| 430 | Ferritic | Magnetic, cost-effective, moderate formability | Appliance panels, automotive trim | 0.5–4 mm |
We offer a full range of China stainless steel sheet fabrication services. We match each process to your part geometry, material grade, tolerance requirements, and production volume.
- Laser Cutting: Our fiber laser systems cut stainless steel sheets from 0.5 mm to 25 mm with positional tolerances to ±0.1 mm. Fiber lasers produce a narrow kerf, clean edges, and a minimal heat-affected zone. We cut all standard stainless grades, including 201, 301, 304, 316, 310S, and 904L.
- CNC Bending and Forming: CNC press brakes achieve bend angle accuracy to ±0.5°. Offline bend sequence programming minimizes springback, which is especially relevant for work-hardening grades like 301 and higher-strength 316. We work with sheet thicknesses up to 12 mm, depending on the material grade and bend radius.
- Welding and Assembly: We perform Metal Inert Gas (MIG), Tungsten Inert Gas (TIG), and spot welding for structural assemblies, enclosures, and multi-part weldments. Weld quality follows AWS and ISO welding standards, with full traceability on materials and process parameters.
- Surface Finishing: Fabricated stainless parts go through a finishing process matched to your application. Options include passivation, electro-polishing, brushed (hairline) finish, mirror polishing (up to 8K), bead blasting, powder coating, painting, and deburring.
- Rapid Prototyping: Prototype orders ship in three to five days. We support design iteration with fast-turnaround stainless steel sheet prototyping, alongside our CNC machining and 3D printing services for early-stage validation.

What Surface Finishes are Available for China Stainless Steel Sheet Fabrication?
Surface finish affects corrosion performance, cleanability, and appearance. The right spec depends on your end application.
- 2B finish: The standard cold-rolled, matte finish for general fabrication and industrial parts. It’s the base condition for most stainless sheets we receive from the mill and the starting point for further finishing.
- Brushed / hairline finish: A directional satin finish produced by abrasive belts. Common on enclosures, architectural panels, and consumer-facing equipment where a clean appearance matters without the cost of mirror polishing.
- Mirror / polished finish: A high-reflectivity surface achieved through progressive polishing steps up to 8K or 10K. Used in pharmaceutical equipment, food processing, and decorative applications. Specifying the correct grit sequence upfront avoids rework.
- Passivation: A chemical treatment that removes free iron and restores the natural chromium oxide passive layer. Required for medical devices and food-contact components to meet hygiene standards.
- Electro-polishing: An electrochemical process that removes a thin surface layer to improve corrosion resistance and achieve lower surface roughness than mechanical polishing alone. Common in pharmaceutical and semiconductor applications.
- Bead blasting: Produces a uniform matte texture that reduces glare and improves paint or powder coat adhesion for parts that go through a secondary coating step.
Different industries have different tolerance requirements, surface standards, and certification expectations. We’ve built specific process experience in each of these sectors, not just general sheet metal capability.
Aerospace
We supply structural brackets, housings, and enclosure panels with full Coordinate Measuring Machine inspection reports and mill test certificates on every order. If your drawing calls for tight positional tolerances and traceable material certification, that’s how every aerospace job ships from our facility.
Automotive
Batch-to-batch consistency is what automotive programs actually require. We fabricate battery enclosures, exhaust components, and structural reinforcements for prototype builds through low- to mid-volume production. Our quality system is ISO 9001 certified, and we maintain IATF 16949 compliance for automotive work. OEM clients rely on our fabricated components in active production.
Medical and Healthcare
Medical enclosures and instrument frames require burr-free edges, traceable material certs, and a quality process that holds up to audits. We manufacture stainless steel housings to medical-grade tolerances with quality processes aligned to ISO 13485 requirements. Passivation documentation is available on request for food-contact and hygienic applications as well.
Electronics and Consumer Products
We supply enclosures, chassis, and mounting hardware to OEMs, where dimensional consistency directly affects assembly yields. Cosmetic finish requirements are quoted and controlled alongside dimensional tolerances, not treated as an afterthought. Prototype enclosures are available in three to five days.
Food and Beverage Processing
Food processing equipment requires 304 or 316L stainless steel with smooth, cleanable surfaces. We fabricate tanks, frames, and conveyor components to food-grade surface standards, with passivation documentation available on request.
Our team at XTJ CNC delivers measurable advantages across your development timeline, budget, and quality output.

Upfront DFM reviews catch design issues before cutting starts. You're iterating on real parts, not waiting on corrections. Faster samples mean faster launches and reduced rework risk.
Lower per-part cost
China-based fabrication gives you access to advanced fiber laser systems and CNC press brakes at a fraction of equivalent Western supplier pricing, without sacrificing tolerances and finish quality.
Scalable volume
Start with a single part. Scale into production batches with the same team, the same quality system, and the same terms with no supplier switch required when your volume grows.
Full traceability
CMM inspection reports and mill test certificates ship with your parts. For regulated industries where documented proof of conformance isn't optional, we treat full traceability and quality documents with the utmost importance.
Every stainless steel part we fabricate passes through a documented inspection process. CMM equipment verifies critical dimensions against your drawing tolerances, and we maintain full material traceability from raw stock to finished part.
- ISO 9001 certified manufacturing: Our quality management system covers process controls, corrective actions, and supplier qualification. This is a step beyond individual part inspections.
- Laser cutting tolerances to ±0.1 mm: Verified on qualifying features, with tighter tolerances achievable on specific dimensions through secondary machining operations.
- Bend angle accuracy to ±0.5°: CNC press brake programming maintains consistent angles across a full batch, critical for enclosures and brackets where mating faces must align.
- IATF 16949 compliance: Available for automotive-related stainless steel work, with First Article Inspection (FAI) reports and Geometric Dimensioning and Tolerancing (GD&T) annotated CMM outputs.
