420 Cold Rolled Stainless Steel Sheet

Key attributes

Products Description

This multi-grade cold rolled stainless steel sheet series stands out with three core customized surfaces: embossed, mirror 8K and hairline brushed, specially developed for diversified modern construction projects, different from previously listed single-surface industrial or decorative steel. Covering full-spectrum austenitic, ferritic and martensitic grades, the product realizes graded material selection from economical civil construction to high-temperature & corrosive environment engineering, becoming all-in-one construction raw material for global building contractors and decoration manufacturers. All sheets adopt precise multi-pass cold rolling + sealed atmosphere annealing craft, stable internal metallographic structure ensures excellent forming performance for bending, grooving, profiling required in building construction.

Grade Classification & Targeted Construction Performance

201 / 202 Low-Nickel Austenitic

Cost-efficient entry-level decorative material with good ductility, easy stamping and bending. Mainly applied for large-area ordinary building interior wall cladding, corridor trim and low-budget commercial facade renovation. Stable anti-rust property under dry indoor atmospheric condition, unsuitable for long-term humid or coastal salt-spray environment. It is the most popular bulk material for large-scale civil construction decoration projects to control overall engineering cost.

304 / 316L Classic Austenitic

304 is mainstream mid-end construction material with balanced corrosion resistance, adaptable to normal indoor & outdoor atmospheric environment, widely used for shopping mall facade, residential building interior decoration and curtain wall facing. 316L adds molybdenum with ultra-low carbon design, outstanding chloride & acid fog resistance, preferred for coastal construction, swimming pool surrounding cladding and chemical factory auxiliary building outer decoration, effectively avoiding pitting rust in high-humidity salt environment. Both grades feature non-magnetic property after processing, excellent polishing adaptability for mirror and brushed finish.

310 / 321 High-Temperature Resistant Austenitic

Special heat-resistant construction stainless steel different from conventional decorative grades. 321 with titanium stabilization eliminates welding intergranular corrosion, stable under 450~850℃ alternating temperature; 310 high chrome-nickel formula bears ultra-high temperature above 1000℃. Two grades are mainly used for industrial furnace outer enclosure, high-temperature workshop building outer panel and thermal pipeline wrapping decoration of construction engineering, solving thermal deformation and oxidation aging problems of common steel under long-term radiant heat.

430 Ferritic / 410&420 Martensitic

430 nickel-free ferritic owns superior polishing performance and cost advantage, ideal for indoor high-end cabinet panel, ceiling decoration and building indoor metal molding. 410/420 martensitic steel can be heat treated for higher hardness and abrasion resistance, processed into construction embedded parts, decorative fasteners and wear-resistant building hardware accessories, widely matched with various architectural decoration components.

Three Custom Finishes Unique for Construction Projects

Mirror 8K Finish: Multiple-step fine mechanical polishing delivers high reflectivity mirror surface, flawless without grinding lines, used for high-end hotel lobby, commercial landmark building interior wall and luxury facade decoration. Compact surface is stain-resistant and easy to clean, greatly improving building grade.

Brushed No.4 Finish: Uniform linear hairline texture with anti-glare effect, scratch-resistant in daily construction use, the most widely used surface for conventional curtain wall, exterior cladding and elevator decorative panel.

Embossed Finish: Various customized concave-convex grain (checkered, water ripple, diamond pattern), anti-slip and scratch-proof, commonly applied for building floor anti-slip panel, wall anti-collision cladding and outdoor landscape architectural decoration. The embossed layer can hide minor construction abrasion during installation.

Production & Construction Matching Advantages

After cold rolling and stress relief annealing, sheets have excellent flatness and low forming rebound rate, smoothly completing complex bending, arc folding and slotting required by architectural personalized modeling. We support on-site fixed-size cutting according to construction drawing to reduce leftover waste during building installation. All finished sheets attach thick PVC protective film to guard mirror/embossed/brushed surface against scratch in transit and construction, tear off film only after full installation to keep original appearance intact.

Packaging & Global Supply Service

Products are packed with moisture-proof kraft paper + plastic wrap for sea and land transportation, complete original mill test certificate attached for international project acceptance and export customs clearance. Free small samples with different surfaces and grades can be provided for customer construction design confirmation before bulk order. Flexible MOQ supports small-batch engineering trial order and large-scale construction bulk procurement.
