Factory Price 420 Ss Arc Spraying Wire For Paper Roll Restoration And Corrosion Resistance - China

420 stainless steel arc spraying wire is a high-cost-performance alloy spraying material provided by a professional alloy trading company, tailored to core industrial needs.

Made from 420 martensitic stainless steel raw materials with a purity of over 99.9%, the wire undergoes precision wire drawing, vacuum annealing, and precision straightening processes to ensure inherent performance stability.

During arc spraying, it forms a coating with a density of ≥95% and a coating-substrate bonding strength of ≥35MPa, effectively resolving industry pain points such as paper roll wear and metal substrate corrosion in harsh environments.

Leveraging our direct procurement supply chain, we offer factory-direct pricing, and also support bulk customization and small-batch trial orders to meet the diverse procurement and application demands of different customers.

Product Features

Superior corrosion resistance: 13-14% chromium content forms a protective passivation film, extending the substrate’s anti-corrosion cycle by 3-5 times.

High wear resistance & restoration capability: Coating microhardness reaches HV550-700, enabling 0.1-5mm precise thickness restoration for damaged paper rolls.

Excellent process compatibility: ±0.02mm diameter tolerance, stable melting and arc combustion, ≤3% splash rate, and compatibility with mainstream spraying equipment.

Outstanding cost-effectiveness: Factory-direct pricing, ≤2% loss rate, 1.2-1.5㎡ coverage per kg, and 15-20% lower comprehensive cost than similar products.

Environmental compliance: Complies with ISO 9001 and RoHS standards, free of harmful impurities and toxic emissions after spraying.

Stable batch consistency: Three full inspections per batch ensure uniform diameter, hardness, and composition of products.

Product Applications

Paper roll restoration & strengthening: Repairs and reinforces papermaking machine rolls (press, guide, coating rolls), restoring roundness error to ≤0.02mm and extending service life by over 3 times.

General metal substrate corrosion protection: Protects carbon steel, cast iron and other substrates in machinery, chemical, marine, and bridge fields from oxidation and chemical erosion.

Wear-resistant component strengthening: Increases the surface hardness of mining, agricultural, and printing equipment parts by 2-3 times, reducing wear and replacement costs.

Special industry applications: Applicable to automotive chassis repair, medical device protection, electronic shell corrosion prevention, and food machinery surface strengthening.
