Conquest Steel & Alloys supplies Rockstar 400 BHN Abrasion Resistant Steel Plates, built for equipment subjected to continuous high-impact wear where standard AR plate wears out fast. At 370–430 HBW, Rockstar 400 sits well above general-purpose 200 BHN plate, making it the grade of choice for crusher liners, haul truck bodies, excavator buckets, and quarry screening equipment. The plate is manufactured to EN 10051 and tested for tensile strength (1250–1600 MPa), yield strength (≥1000 MPa), and elongation (10–12%), giving fabricators documented mechanical data instead of a generic hardness claim. Chromium and nickel alloying in the composition improves both wear resistance and impact toughness, so the plate holds its hardness under repeated impact rather than just resisting surface scratches. Rockstar 400 is available as standard plates, thinner sheets, and pre-profiled liner plates, in thicknesses from 6mm to 100mm, widths up to 2500mm, and lengths up to 12000mm. Custom cutting and sizing to project drawings is available on request, reducing on-site fabrication work for high-volume orders.
Conquest Steel & Alloys is a Delhi-based manufacturer, supplier, and exporter of steel plates across the full abrasion-resistant hardness range, including 200 BHN, AR400-class, and Rockstar 400. Every batch passes macro testing, micro testing, hardness testing, toughness testing, destructive testing, and PMI testing before dispatch, so buyers receive plate that matches its specification sheet — with documentation to back it up. For procurement teams sourcing wear parts for mining, quarry, or heavy construction equipment, Rockstar 400 offers a middle ground between fabrication practicality and serious impact resistance. Combined with the ability to source lighter AR grades from the same supplier, teams can specify different hardness plates for different wear zones on the same equipment without splitting orders across vendors.

Rockstar 400 is a through-hardened steel plate built for continuous high-impact abrasion — the kind of wear that eats through mild steel in weeks, not years. At 370–430 HBW, it sits a full grade above standard 200 BHN plate, which is why it shows up in crusher liners, quarry buckets, and haul truck bodies rather than lighter chute work.
The hardness holds through the full plate thickness, not just the surface. That matters for parts that get re-cut or re-drilled during fabrication — the wear resistance doesn't disappear once you machine past the top layer.
Rockstar 400 plate goes wherever equipment absorbs constant impact from rock, ore, or heavy aggregate — not just surface friction. Typical uses:
If your application is 200 BHN territory — general liners, light structural wear — Rockstar 400 is more plate than you need and harder to weld. It earns its place when the wear is heavy and constant.
Under-specifying hardness on a high-impact part means replacing it in months instead of years. Rockstar 400's 370–430 HBW range is built for exactly the wear zones where 200 BHN plate would deform or gouge quickly — crusher jaws, bucket edges, truck beds taking direct rock impact.
The trade-off is fabrication difficulty. Higher hardness means more careful welding procedures and less forgiving bending. Getting the grade right the first time avoids both premature failure on the low end and unnecessary fabrication cost on the high end.
Rockstar 400 is supplied in a few forms depending on how it's going into your equipment:
| Specification | Details |
|---|---|
| Grade | Rockstar 400 |
| Hardness | 370 – 430 HBW |
| Thickness | 6 mm to 100 mm |
| Width | Up to 2500 mm |
| Length | Up to 12000 mm |
| Standard | EN 10051 |
| Form | Plates, Sheets, Liner Plates |
Conquest Steel & Alloys is a Rockstar 400 Plate Supplier in India, with custom cutting available to project drawing.
| Property | Value |
|---|---|
| Tensile Strength | 1250 – 1600 MPa |
| Yield Strength | ≥ 1000 MPa |
| Elongation | 10 – 12% |
| Impact Toughness | Excellent |
These figures hold up under sustained mechanical stress, which is what separates Rockstar 400 from lighter-duty AR grades in continuous high-impact settings.
| Element | Composition (%) |
|---|---|
| Carbon (C) | 0.12 – 0.20 |
| Manganese (Mn) | 1.00 – 1.60 |
| Silicon (Si) | 0.20 – 0.70 |
| Chromium (Cr) | 0.50 – 1.50 |
| Nickel (Ni) | 0.25 – 1.00 |
| Boron (B) | Trace |
The chromium and nickel content is what pushes wear resistance and toughness above a plain carbon plate — it's the reason Rockstar 400 holds its hardness under repeated impact instead of just resisting surface scratches.
Conquest Steel & Alloys manufactures, supplies, and exports steel plates across multiple hardness grades from our Delhi facility, serving mining, construction, and industrial machinery buyers domestically and internationally.
We supply across the full abrasion-resistant range — from 200 BHN general-purpose plate up to Rockstar 400 for high-impact wear parts — to construction, infrastructure, and precast industries. Every plate ships with documented mechanical and chemical properties: tensile strength, yield strength, and full chemical composition, tested per batch rather than quoted from a spec sheet.
Plates are manufactured to EN 10051 and other applicable national and international standards, and test reports are available on request. Before any batch leaves the facility, it goes through macro testing, micro testing, hardness testing, toughness testing, destructive testing, and PMI testing. That's the difference between a plate that matches its paperwork and one where you find out the hard way, mid-project.
What buyers get working with us:
What does 400 BHN mean, and how is it different from 200 BHN plate?
BHN measures Brinell hardness. Rockstar 400 sits at 370–430 HBW — roughly double a 200 BHN plate. That extra hardness handles heavier, more constant impact, but it comes at a cost: the plate is harder to weld and bend.
Can Rockstar 400 plate be welded on site?
Yes, with more care than 200 BHN plate needs. Pre-heating and welding procedure matter more at this hardness level. Ask our team for welding guidance specific to your fabrication setup before you start cutting.
What's the difference between Rockstar 400 and AR500?
Rockstar 400 sits between mid-range and top-tier AR grades — harder than AR200 or AR235, more fabrication-friendly than AR500 (470–540 HBW), which is reserved for the most extreme impact zones.
What thickness range do you supply for Rockstar 400?
6mm to 100mm, widths up to 2500mm, lengths up to 12000mm. We cut to project drawing on request.
Do you provide test certificates with Rockstar 400 orders?
Yes — every batch is tested (macro, micro, hardness, toughness, destructive, PMI) and certificates ship with your order, not on a separate request.
Do you supply Rockstar 400 outside Delhi or for export?
We supply across India and export internationally. Dispatch timelines get confirmed at the time of quote, based on your location and order volume.
Rockstar 400 BHN plate earns its place on equipment where the wear is constant and the impact is real — crusher liners, haul truck beds, quarry buckets. At 370–430 HBW, it holds up to abuse that would gouge or deform a 200 BHN plate within a season, and Conquest Steel & Alloys backs every batch with tested tensile strength, yield strength, and chemical composition data, not a vague hardness rating.
Manufactured to EN 10051 and supplied from our Delhi facility in thicknesses from 6mm to 100mm, Rockstar 400 is available as plates, sheets, or pre-profiled liner sections — cut to your project drawing rather than shipped as generic flat stock. Every order comes with macro, micro, hardness, toughness, destructive, and PMI test certificates, so what you specify is what arrives.
Getting the hardness grade right matters more than it might seem. Over-spec, and you're paying for fabrication difficulty you didn't need. Under-spec, and you're replacing liners and buckets on a schedule that eats into uptime. Because we also supply 200 BHN and other AR grades, our team can help you match the right plate to each wear zone on your equipment instead of defaulting to one grade for everything.
