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.

• 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.
