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（亮退火，在EN 10088‑2中标记为2R）不锈钢卷材是一种优质冷轧不锈钢卷材，在无氧保护气氛中进行退火处理，且不经酸洗。其表面极度光滑、明亮且具有高反射性，比标准2B表面处理更为光亮。 作为进一步抛光制成8K镜面、HL发丝纹及彩色装饰表面的基材，该产品具有更低的表面粗糙度、更洁净的表面、更少的缺陷以及更优异的可清洁性，非常适合卫生级和食品级应用。表面覆有保护性PE薄膜，以防止在分条、冲压、弯曲和运输过程中产生划痕。.
8K镜面（No.8）不锈钢卷材是一种高品质抛光冷轧不锈钢卷材，是在2B/BA基材上经过多道精细研磨和抛光工艺制成，可实现如玻璃般的镜面反射、清晰的图像反射、低雾度以及整个卷材表面光泽均匀。 作为高端装饰性不锈钢表面处理工艺，它被加工商、电梯厂、建筑承包商和标牌制造商广泛选用。 与哑光2B、HL发丝纹或No.1热轧表面不同，8K镜面表面不仅具有超平滑的表面和卓越的装饰性能，同时还保留了原有的耐腐蚀性和延展性。可根据要求提供PVD彩色镜面卷材（金色、玫瑰金、黑钛、香槟色）。.
HL发丝纹不锈钢卷材，又称长线拉丝不锈钢卷材，采用优质2B或BA冷轧基材，经连续砂带打磨工艺处理，使整个卷材表面形成细腻、均匀、笔直的发丝状线性纹理。 与4号短拉丝表面处理相比，HL表面纹理更长、更平滑、更显优雅，被广泛应用于中高端建筑及电梯装饰项目。 发丝纹表面能有效遮盖细微划痕和指纹，日常维护比8K镜面抛光更便捷。可根据要求提供PVD着色发丝纹不锈钢卷材（金色、玫瑰金、黑钛、香槟色）。.
