Our Stainless Steel Processing Capabilities
Main Stainless Steel Grades & Surface Finishes
304 Stainless Steel
Great rust resistance, easy bending and welding performance. Available forms: stainless steel coils, slit strips and wire rods.
Processing Tip:
Perfect for stamping, deep drawing and mass continuous production.
316L Stainless Steel
Excellent acid & seawater corrosion resistance with low carbon property. Available forms: tolerance precise coils and drawing wire rods.
Processing Tip:
Resists intergranular corrosion after welding for harsh corrosive environments.
201 Stainless Steel
Economical stainless steel grade with basic anti-rust performance. Available forms: mass stocked coils and wire rods for bulk orders.
Processing Tip:
Cost-effective option for indoor low-corrosion usage scenarios.
430 Stainless Steel
Stable ferritic structure with outstanding heat resistance. Available forms: cold rolled coils and forming wire rods.
Processing Tip:
Not suitable for strong acid and salt heavy corrosion working conditions.
2B Cold Rolled Finish
Standard industrial matte base surface for secondary processing. Applicable products: coils & wire rods of 201, 304, 316L, 430 grades.
Processing Tip:
Most cost-effective base surface for large-scale manufacturing.
BA Bright Annealed Finish
Smooth semi-mirror bright surface formed by protective atmosphere annealing. Applicable products: coils and fine wire rods of mainstream stainless steel grades.
Processing Tip:
Can be directly applied without extra polishing cost.
Only mainstream grades & surfaces displayed. Custom grades and special finishes are available upon request.

Finish Specs
Materials
Technical Description & Cost
As machined
Metals & Plastics
Raw finish directly from CNC. The most economical choice with tightest tolerances. Visible tool marks present.
Smooth machining
Metals & Plastics
Machined at lower feed rates. Less visible tool marks, better sealing properties and reduced friction.
Polishing
All Materials
Smoothing to remove tool marks. Essential for optical parts, molds, or reducing friction.
Bead Blasting
Plastics
Bombarded with glass beads for a uniform matte finish. Hides tool marks. Note: Affects dimensions.
Tumbled
Plastics
Batch process with vibrating media. Removes sharp edges (deburring) and smooths geometry.
Anodizing Type II (Matte)
Aluminum
Corrosion-resistant oxide layer. Matte finish achieved by bead blasting prior to anodizing. Non-conductive.
Anodizing Type II (Glossy)
Aluminum
Standard Type II anodizing applied to a polished/smooth surface. Vibrant, shiny appearance.
Anodizing Type III (Hardcoat)
Aluminum
Thick, dense oxide layer (25-50μm). Extreme wear resistance (60-70 HRC). Limited color options (Dark).
Powder Coated
All Metals
Dry powder fused by heat. Strong, thick plastic skin (~80μm). Superior durability to wet paint.
Black Oxide
Conversion coating. Anti-glare, mild corrosion resistance (needs oil). Negligible thickness change.
Chromate (Alodine)
Aluminum
Corrosion protection for aluminum that remains electrically conductive. Great paint primer. Cost-effective.
Plating
All Metals
Depositing metal (Nickel, Zinc, Chrome) for solderability, hardness, or corrosion resistance.
DLC Coating
Diamond-Like Carbon. Extremely hard, low-friction. Used in engines, tools, and luxury watches.
