熱間圧延ブラックスキンステンレス鋼線材

Hot Rolled Black Skin Stainless Steel Wire Rods, also named Pickled Wire / Acid Washed Wire / No.1 Finish Wire / Black Wire, are processed by route: hot rolled wire rod → annealing → pickling & passivation to remove oxide scale → surface finishing, without cold drawing & brightening procedures. The surface presents dark grey / grey-black matte appearance without metallic luster, uniform rust-free surface with no obvious oxide scale. With passivation film for stable rust resistance, dimensional tolerance ±0.1mm, high hardness and great tensile strength, the raw material cost is lower than bright annealed wire. Widely used as raw material for industrial welding wire, steel structure fasteners, heavy mechanical parts, pipe connectors, wear-resistant components, construction hardware and heavy industrial equipment accessories for global manufacturing & infrastructure sectors.
In-stock diameter range: 1.0mm–60.0mm; customized heavy thick wire: 60.0mm–120.0mm

製品の性能

Defined production process without brightening treatment

Manufactured by fixed procedure: hot rolled wire rod → annealing → pickling & passivation for oxide removal → surface finishing, no cold drawing and bright annealing step, matching cost-oriented bulk processing demand.
Natural matte pickled passivation surface

Dense anti-corrosion passivation layer formed on surface after pickling treatment, stable rust-proof performance, uniform appearance without rust spots and residual heavy oxide skin.
Economical dimension control for general industrial processing

Diameter tolerance controlled at ±0.1mm, high hardness and tensile property, qualified for conventional cold drawing, cold heading and bending procedures for non-appearance-critical products.
Cost-effective alternative for non-high-surface requirement scenarios

Lower raw material cost compared with pickled bright wire rods, ideal base material for customers arranging secondary surface treatment afterward.

製品の用途

Industrial welding wire, steel structure fasteners, heavy mechanical accessories, pipe connecting parts, wear-resistant components, construction hardware, heavy industrial equipment fittings, widely adopted in global general manufacturing and infrastructure construction industries.
