N02200 is high-purity face-centered cubic commercial pure nickel bright bar.

Two core unique strengths:

1. Unmatched caustic alkali resistance across all concentrations of NaOH up to 315℃, superior to all stainless steel & duplex grades;

2. Excellent electrical/thermal conductivity and ultra-high ductility, elongation ≥40% in annealed condition, ideal for deep drawing, cold heading and bending.

N02201 (Nickel 201, low carbon C≤0.02%) is upgraded variant for service above 315℃; N02200 with higher carbon suffers graphitization & embrittlement under long-term heat above 315℃.

Non-hardenable by quenching without martensitic transformation; annealing at 700~925℃ relieves cold work stress and restores ductility. Wide hot forming window 800~1150℃, easy for mass CNC turning, low tool built-up edge risk vs duplex & martensitic steel.

Limitations: No Cr/Mo leads to poor pitting resistance in seawater, brine and strong oxidizing acid. Max continuous service temperature 315℃, not allowed for sustained high-temperature dry heat. Higher raw material cost than standard 300/400-series stainless steel.

Chemical element content (%)

Specification：1.00~300.00mm

Application:It is mainly used to manufacture internal pins for caustic soda evaporators, fasteners for chlor-alkali reactors, anti-corrosion core rods for salt production, conductive electrodes for electroplating lines, lithium battery connecting terminals, valve bars for food ambient alkali washing equipment, chloride-free standard parts for civil hot air dryers, internal bars for electronic vacuum tubes, support bolts for low-temperature chemical dryers, low-cost conductive CNC turning small components, etc.
Widely applied in complete caustic/chlor-alkali chemical plants, salt processing lines, electroplating anti-corrosion facilities, power battery conductive accessories, food ambient alkali treatment equipment, civil hot air drying machinery, precision electronic components and general hardware for indoor dry environments.

Core Advantages Over Competitors

1. High quality stability: Full closed-loop production & online spectral inspection strictly control C, Ni, Fe with high uniform nickel purity. Consistent ductility, caustic resistance and conductivity ensure stable mass supply of chlor-alkali and electronic conductive components.

2. Excellent surface quality: High-precision cold drawing & centerless grinding lines produce smooth bar free of scale, scratches and pits. Clean surface after turning eliminates secondary polishing for electrodes & appearance parts.

3. Ultra-high dimensional accuracy: Precision rolling mills & automatic online detectors narrow tolerance range with tiny single-bar deviation and high batch uniformity, unifying component sizes in automatic mass production to raise finished yield.

4. Rich product variety: According to market demand and customer's special requirements, customized products are provided to meet the use requirements under various complex working conditions, providing customers with more choices.

5. Perfect after-sales service: The perfect after-sales service system can respond to customer needs and feedback in a timely manner. For problems encountered by customers during use, technical support and solutions are provided to customers quickly.
