2B Finish Stainless Steel Coil
2B finish stainless steel coil is the most widely‑used cold‑rolled stainless steel coil in global industry. Produced by cold rolling, annealing, pickling/descaling and light skin‑pass rolling with polished rolls, it delivers a smooth, uniform semi‑matte surface with moderate reflectivity and Ra 0.1‑0.5μm. As a universal base finish, it can be further processed into HL hairline, No.4 brushed, 8K mirror, PVD colored or embossed surfaces. It combines excellent corrosion resistance, good formability, stable flatness and competitive cost, ideal for bending, deep drawing, stamping, welding and decoiling operations.

Product Features
- Widely‑adopted base surface: The 2B finish is standard cold‑rolled skin‑pass surface with stable Ra 0.1‑0.5μm, smooth uniform semi‑matte appearance for most downstream processing scenarios.
- Excellent secondary processing compatibility: Suitable for further finishing including HL hairline, No.4 brushing, 8K mirror polishing, PVD coloring and embossing to meet diverse decorative and functional demands.
- Broad grade portfolio: Covers 200, 300, 400 series austenitic, ferritic, martensitic stainless steel as well as 2205, 2507 duplex stainless steel for different corrosion and strength requirements.
- Flexible customizable dimensions: Thickness from 0.1‑3.0mm, width 1000‑2000mm, inner ID 508/610mm or custom‑made to satisfy various project procurement.
- High‑precision dimensional control: Thickness tolerance ±0.02mm reduces material loss during slitting and decoiling.
- Complete certification support: ISO9001 and CE certifications available, third‑party inspection is acceptable, documents complying with buyers’ local regulations can be provided.
- Reliable seaworthy export packing prevents oxidation and mechanical damage during long‑distance transportation.
Typical Performance
- Outstanding corrosion resistance: Good resistance to pitting and intergranular corrosion under acid, alkali and chloride‑rich environments, suitable for chemical and marine harsh working conditions.
- Superior processing & forming performance: Good ductility and plasticity for bending, deep drawing, stamping and welding, maintaining stable surface quality after fabrication.
- Consistent flatness: Cold‑rolled skin‑pass process ensures flat sheet surface and uniform thickness for higher yield in slitting and stamping.
- Cost‑effective comprehensive performance: Balances corrosion resistance, formability and flatness, works as preferred general‑purpose raw material for mass industrial applications.
Main Applications
- 🏭 Pipe Fitting Manufacturing: Raw coil material for stainless steel elbows, flanges and other pipe fittings.
- ⚗️ Chemical, Pharmaceutical & Bio‑Medical: Structural and lining materials for chemical and pharmaceutical production equipment.
- 🛢️ Petrochemical & Refinery: Corrosion‑resistant material for refining process equipment and pressure vessels.
- 🏗️ Architecture: Material for building curtain walls, decorative panels and profile components.

BA (Bright Annealed, marked as 2R in EN 10088‑2) stainless steel coil is premium cold‑rolled stainless steel coil annealed in oxygen‑free protective atmosphere without pickling. It delivers an ultra‑smooth, bright, highly reflective mill surface, brighter than standard 2B finish. As base material for further polishing into 8K mirror, HL hairline and colored decorative surfaces, it features lower surface roughness, cleaner surface, fewer defects and superior cleanability, ideal for sanitary and food‑grade applications. A protective PE film is laminated to prevent scratches during slitting, stamping, bending and shipment.
8K Mirror (No.8) stainless steel coil is high‑grade polished cold‑rolled stainless steel coil, manufactured by multi‑stage fine grinding and buffing on 2B / BA base material to achieve glass‑like specular reflection, clear image reflection, low haze and uniform gloss across the whole coil. As the premium decorative stainless steel finish, it is widely selected by fabricators, elevator factories, architectural contractors and signage makers. Unlike matte 2B, HL hairline or No.1 hot‑rolled surfaces, the 8K mirror finish features an ultra‑smooth surface and excellent decorative performance while retaining the original corrosion resistance and ductility. PVD colored mirror coil (gold, rose gold, black titanium, champagne) is available on request.
HL hairline stainless steel coil, also known as long‑line brushed stainless steel coil, is processed from premium 2B or BA cold‑rolled substrate with continuous abrasive belt grinding to create fine, uniform, straight hair‑like linear grain across the whole coil. Compared with No.4 short‑brush finish, HL features longer, smoother and more elegant streaks, widely adopted for mid‑to‑high‑end architectural and elevator decoration projects. The hairline surface effectively hides minor scratches and fingerprints for easier daily maintenance than 8K mirror finish. PVD colored HL coil (gold, rose gold, black titanium, champagne) is available upon request.
