What is XAR 500?

XAR 500 (NM500) is a higher-hardness quenched-and-tempered wear plate at about 450–540 HB (nominal 500 HB, 50 HRC), with 1300 MPa yield, 1700 MPa tensile and 8 % elongation. Engineers select it over 400 HB plate when sliding abrasion dominates in crusher liners, dump bodies and mining wear parts, and it is available as plate including flame-cut blanks. Formability and weldability drop with hardness: bend radii of 4–5× thickness, 150–200 °C preheat, and a 250 °C service ceiling. It is the equivalent of Hardox 500; use XAR 400 where more bending and welding is required. XAR 500 has a density of 7.85 g/cm³ (0.284 lb/in³), heavier than 56% of steel grades. It melts at 1,420°C (2,588 °F). XAR 500 has a yield strength of 1,300 MPa (189 ksi) and a tensile strength of 1,700 MPa (247 ksi) — stronger than 95% of steel grades. Elongation at break is 8% and the elastic modulus is 210 GPa (30.5 Msi).

Working with XAR 500

Is XAR 500 easy to machine?

Treat as ~50 HRC hardened steel: rigid setup, negative-rake carbide or CBN, low speed / adequate feed, flood coolant; prefer drilling by carbide-tipped or hard-metal drills, or plan holes by laser/waterjet.

Can XAR 500 be welded?

Weldable with low-hydrogen (H5) consumables of lower strength than base metal; preheat 150–200 °C (thicker/higher CEV to 200 °C), interpass ≤225 °C, control heat input and avoid restraint cracking — do not PWHT above the tempering temperature.

Can XAR 500 be formed, bent or molded?

Cold bending possible with punch radius ≥4–5×t (bend axis transverse to rolling direction), generous die opening and de-burred, ground edges; hot forming destroys the Q&T hardness.

XAR 500 — frequently asked

What is XAR 500 used for?

XAR 500 is typically used for crusher liners, dump bodies and mining equipment wear parts. In short: 500 HB severe-abrasion plate; hardox 500 equivalent; still field-weldable.

What is the yield strength of XAR 500?

XAR 500 has a typical yield strength of 1,300 MPa (189 ksi) and a tensile strength of 1,700 MPa (247 ksi) — stronger than 95% of steel grades. Strength varies by condition: see the 3 listed tempers.

Is XAR 500 easy to machine?

Not especially — machinability is rated not recommended (12/100, worse than 99% of steel grades). Treat as ~50 HRC hardened steel: rigid setup, negative-rake carbide or CBN, low speed / adequate feed, flood coolant; prefer drilling by carbide-tipped or hard-metal drills, or plan holes by laser/waterjet.

Can XAR 500 be welded?

With care — weldability is rated fair (45/100). Weldable with low-hydrogen (H5) consumables of lower strength than base metal; preheat 150–200 °C (thicker/higher CEV to 200 °C), interpass ≤225 °C, control heat input and avoid restraint cracking — do not PWHT above the tempering temperature.

What surface finishes work on XAR 500?

Blast and paint or apply zinc-rich primer for corrosion protection; no anodizing — for extreme wear, combine with chromium-carbide hardfacing overlays.

Can XAR 500 be formed, bent or molded?

Cold bending possible with punch radius ≥4–5×t (bend axis transverse to rolling direction), generous die opening and de-burred, ground edges; hot forming destroys the Q&T hardness.

What is the maximum service temperature of XAR 500?

XAR 500 is rated for continuous use to about 250°C (482 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.

What is the difference between XAR 500-QT and XAR 500 QT-TUF?

QT is the default condition — standard mill-delivered condition for XAR 500 plate, 4–65 mm; pick for severe sliding abrasion where impact loading is moderate. QT-TUF: choose when the 500 HB wear class must also survive impact/cold service — tighter chemistry and cleanliness give guaranteed CVN at −40 °C. Yield strength is 1,300 MPa in QT versus 1,350 MPa in QT-TUF.

How much does XAR 500 cost?

XAR 500 is a budget-cost steel ($), cheaper than about 90% of the materials FabDigit quotes. Part price depends far more on geometry, tolerance and quantity than on the raw stock — upload a CAD file for a live quote.
