AR400 wear plate is a quenched and tempered abrasion-resistant steel plate used in equipment exposed to sliding wear, impact, and continuous material handling abrasion. As an AR400 wear plates supplier India, Stancor supports OEMs, fabricators, EPC contractors, plant maintenance teams, and industrial buyers that require reliable plate availability, dimensional consistency, hardness control, and processing support for wear applications.
AR400 is commonly selected when the requirement is to improve service life over mild steel without moving to a significantly harder grade that may reduce fabrication convenience. In practical terms, it is used where ore, coal, clinker, limestone, sand, aggregates, scrap, grain, ash, and similar bulk materials cause rapid surface loss in standard carbon steel. The grade offers a useful balance of abrasion resistance, weldability, formability, and workshop processing for many industrial wear parts.
What Is AR400 Wear Plate?
AR400 is an abrasion-resistant steel plate produced through controlled alloy chemistry and heat treatment, typically quenching and tempering, to achieve a nominal hardness class around 400 Brinell. The designation does not indicate one exact hardness number across every plate; rather, commercial supply generally falls within a hardness band, often around 360-440 BHN, depending on thickness, mill route, and specification.
Compared with ordinary structural steel plate, AR400 provides substantially better resistance to abrasive wear. This makes it suitable for liners, transfer points, buckets, dump bodies, hoppers, chutes, crusher components, wear strips, and similar parts where material flow continuously removes metal from the surface. For buyers evaluating wear plate grades, AR400 is often the practical starting point when both wear life and fabrication efficiency matter.
AR400 Wear Plates Supply in India
Stancor supplies AR400 wear plates in India in forms aligned to fabrication and maintenance requirements. Procurement is not only about plate price per kilogram; industrial buyers also evaluate flatness, thickness tolerance, hardness consistency, edge condition, traceability, cutting quality, and delivery commitment. These factors directly affect shop productivity and field performance.
Supply can be arranged for:
- Full-size AR400 plates
- Cut-to-size plates for fabrication nests
- Profile-cut wear components as per drawings
- Shutdown and maintenance quantities for replacement liners
- Project-based supply for OEMs and plant expansions
- Documentation-backed material where test certificates are required
For many users searching specifically for an AR400 wear plates supplier in India, the decision depends on whether the supplier can support both commercial and technical requirements: correct grade identification, dependable source, processing capability, and dispatch reliability.

Industries and Applications for AR400 Wear Plate
AR400 is used across sectors where abrasive solids move, fall, slide, or impact against steel surfaces. The grade is not limited to one industry; its suitability depends on wear mechanism, expected service life, fabrication method, and replacement economics.
Common application sectors include:
- Mining and quarrying: liners, rock boxes, loading bins, chute sections, screen feed areas
- Cement and clinker handling: hoppers, transfer chutes, duct transitions, wear liners
- Power and ash handling: coal bunkers, ash chutes, transfer points, feeder components
- Construction equipment: buckets, side cutters, dump bodies, wear strips, reinforcement plates
- Recycling and scrap handling: shredder feed zones, scrap bins, liners, impact-prone wear surfaces
- Agriculture and bulk solids: grain handling components, conveyors, hoppers, slide surfaces
- Steel and process plants: raw material handling equipment, transfer points, abrasion-prone guards and liners
Where wear is mainly sliding abrasion with moderate impact, AR400 often provides a cost-effective increase in service life over standard plate. Where impact is severe or abrasion is extreme, grade selection may need review against higher hardness wear plate or alternate liner systems.
Why Buyers Specify AR400 Instead of Mild Steel
The main reason AR400 is specified is reduced wear loss under abrasive service. Mild steel may be easy to fabricate, but in many material handling environments it wears rapidly, leading to unplanned replacement, shutdown time, and recurring fabrication cost. AR400 helps extend maintenance intervals while remaining workable in many shop conditions.
- Improved abrasion resistance: better wear life than conventional carbon steel in sliding abrasion service.
- Balanced hardness: hard enough for many industrial wear duties without automatically requiring the highest hardness class.
- Fabrication practicality: suitable for cutting, welding, and forming under proper procedures.
- Versatility: used in both OEM manufacturing and maintenance replacement work.
- Commercial availability: commonly sourced in plate form and processed into finished wear parts.
For procurement teams, the relevant comparison is not only plate purchase price but installed cost over service life. A wear plate that lasts longer and fits correctly can reduce downtime, labor, and repeat replacement frequency.
Processing, Fabrication, and Procurement Considerations
When ordering AR400 wear plate, the technical and commercial details should be aligned before dispatch. Buyers often specify dimensions, thickness, hardness class, quantity, plate nesting requirements, and whether profile cutting or edge preparation is needed. For fabricated wear parts, drawing revision control and tolerances are equally important.
Typical procurement checkpoints include:
- Required thickness and plate size
- Application type: sliding wear, impact, or mixed service
- Need for cut-to-size or profile-cut parts
- Hardness range and documentation requirements
- Flatness and dimensional tolerance expectations
- Quantity for shutdown, annual rate contract, or project supply
- Delivery schedule and destination within India
In workshop practice, AR400 can generally be cut and welded using established procedures suitable for abrasion-resistant plate. However, fabrication parameters should be selected according to thickness, restraint, consumables, and service conditions. If the component is wear-critical, buyers should confirm that the supplied material is appropriate for the intended duty rather than relying only on a generic grade name.
How to Evaluate an AR400 Wear Plates Supplier in India
Industrial sourcing teams typically compare more than one supplier before placing orders. For wear plate, the most useful evaluation criteria are technical consistency and supply reliability rather than headline pricing alone.
A practical supplier assessment should include:
- Availability across commercially relevant thicknesses
- Ability to supply full plates and processed parts
- Traceability and test documentation support
- Understanding of wear applications and grade suitability
- Consistency in dispatch timelines
- Capability to support repeat industrial orders
- Commercial responsiveness for urgent maintenance requirements
Stancor supplies AR400 wear plates in India for industrial wear applications where buyers need dependable material support for fabrication and replacement schedules. Enquiries can be aligned to drawings, dimensions, processing scope, and destination requirements to streamline procurement.
