Ar400 Steel Sheet Overview

Ar400 Steel Sheet—commonly referred to as ar400 plates—is a quench-and-tempered abrasion-resistant steel engineered to deliver a nominal 400 HBW hardness (typically ~360–440 HBW). This balance of hardness and toughness makes it a go-to solution in wear resistant steel plate applications where sliding abrasion, moderate impact, and extended service life are priorities. Compared with mild steel, AR400 can significantly increase component longevity, enabling thinner sections without compromising wear performance.

From a technical standpoint, Ar400 Steel Sheet generally offers high yield strength, excellent flatness, and consistent through-thickness hardness. Typical supply ranges span ~4–80 mm thickness with common widths up to 2000–2500 mm, and lengths tailored to project needs. The material is weldable with appropriate procedures (e.g., controlled heat input and preheat based on thickness), machinable using carbide tooling, and available in ar400 formable variants to support bending and roll-forming with appropriate radii.

Xingtai Baidy Steel Works Co., Ltd. supplies a full portfolio of abrasion-resistant grades, including NM360, NM400, NM450, and NM500, allowing engineers to match wear mechanisms with the right hardness. Backed by rigorous quality control and responsive service, Baidy facilitates on-time delivery and project-specific processing—helping OEMs and end users implement AR solutions with confidence.

Benefits & Use Cases of Ar400 Steel Sheet in wear resistant steel plate

Ar400 Steel Sheet excels in high-abrasion environments across mining, aggregates, cement, recycling, forestry, agriculture, and construction equipment. Common components include truck and dumper bodies, dozer and loader buckets, bucket sides/cutting edges, hoppers, feeders, chutes, liners, screen plates, crusher sidewalls, conveyor skirting, and wear bars. In these settings, ar400 plates deliver robust resistance to gouging and sliding wear, helping operators extend maintenance intervals and protect structural substrates.

Key advantages include predictable hardness, reliable flatness for efficient fabrication, and availability in ar400 formable variants for cold bending and shaping. With proper welding practices and matched consumables, AR400 integrates smoothly into mixed-steel assemblies. The material’s combination of hardness and toughness supports both impact-prone and abrasive flows, reducing the risk of premature failure while minimizing weight compared to over-engineering with mild steel overlays.

Xingtai Baidy Steel Works Co., Ltd. brings application know-how to every order—advising on grade selection (NM360 to NM500), thickness optimization, bend radii, and shop practices for cutting, drilling, and welding. With in-house processing for cut-to-size parts and project kits, Baidy shortens lead times and simplifies procurement for OEMs, EPCs, and maintenance teams that demand dependable wear solutions at scale.

Cost, Maintenance & User Experience

Total cost of ownership with Ar400 Steel Sheet hinges on fewer replacements, shorter stoppages, and optimized part weight. While the unit price is higher than carbon-manganese steels, AR400’s wear life can substantially outlast mild steel in abrasive service, reducing liner changeouts, labor, and lost production. In many plants, switching to ar400 plates enables thinner sections that cut dead weight, yielding fuel and handling efficiencies without sacrificing durability.

Maintenance best practices include: selecting proper fasteners and isolation to limit fretting; rotating or flipping wear liners where design allows; using compatible filler metals and preheat based on thickness during welding; and storing plates dry to prevent surface oxidation before fabrication. Customers in quarrying, cement, and recycling report more consistent wear patterns and fewer unscheduled interventions after standardizing on AR400, particularly when parts are precision-cut and fitted to minimize turbulence and impact points. Xingtai Baidy Steel Works Co., Ltd. supports these outcomes with reliable tolerances, clear fabrication guidance, and responsive after-sales consultation—helping operators realize ROI quickly in uptime-critical environments.

Sustainability & Market Trends in steel industry

Sustainability priorities and cost pressures are accelerating adoption of abrasion-resistant steels. By extending component life, Ar400 Steel Sheet helps reduce material consumption, fabrication waste, and transport emissions associated with frequent replacements. In parallel, the circular economy—driven by recycling, aggregates reclamation, and higher throughput in bulk handling—requires robust wear solutions that maintain equipment efficiency over longer intervals.

Xingtai Baidy Steel Works Co., Ltd. positions customers for these trends through reliable supply, yield-focused nesting and cutting services that minimize offcuts, and logistics planning that consolidates shipments to reduce handling. The company’s portfolio spanning NM360 to NM500 enables “right-hardness” engineering—avoiding over-specification and unnecessary mass. As regulatory expectations evolve and operators seek measurable lifecycle gains, Baidy’s emphasis on application-matched grades, processing precision, and technical guidance supports both operational performance and sustainability goals across the steel products value chain.
