Material range

Three steel grades for three levels of load.

Each WINOX grade is designed for a specific range of tasks — from standard structures to extreme operating conditions. Choose the material by wear level, and we'll help with processing and delivery.

WINOX WL 400 — LIGHT

WL 400

WL 400 is a basic wear-resistant steel with guaranteed hardness of 400 HBW. The optimal choice for components that need a balance of wear resistance and processing ease.

360–420 HBWBrinell hardness

~1,000 MPaYield strength

~1,250 MPaTensile strength

≥30 J (-40 °C)Impact toughness

Chemical profile

C ≤ 0.20%
Si ≤ 0.80%
Mn ≤ 1.60%
Cr + Mo + Ni — balanced composition

Processability

Cuts well with plasma and laser
Bends on standard press brakes
Weldable with 100–150 °C preheat

Excavator buckets, blades, conveyor trays, dump truck bodies, bunkers.

Preheat to 100–150 °C and use low-hydrogen electrodes when welding.

WINOX WM 450 — MEDIUM

WM 450

WM 450 is an enhanced hardness steel for components operating under intensive abrasive and impact loads. Optimal combination of wear resistance and machinability.

420–480 HBWBrinell hardness

~1,200 MPaYield strength

~1,450 MPaTensile strength

≥25 J (-40 °C)Impact toughness

Chemical profile

C ≤ 0.26%
Si ≤ 0.80%
Mn ≤ 1.60%
Cr + Mo + Ni — increased alloying elements

Processability

Plasma or laser cutting
Bending with larger radius than WL 400
Welding with 150–200 °C preheat

Bunker linings, crusher jaws, screws, mixer blades, mining equipment parts.

Mandatory preheat to 150–200 °C before welding. Slow cooling after welding.

WINOX WX 500 — EXTRA

WX 500

WX 500 is a maximum hardness steel for extreme conditions. Designed for components where wear occurs fastest and standard materials cannot withstand.

470–540 HBWBrinell hardness

~1,300 MPaYield strength

~1,600 MPaTensile strength

≥20 J (-40 °C)Impact toughness

Chemical profile

C ≤ 0.30%
Si ≤ 0.80%
Mn ≤ 1.60%
Cr + Mo + Ni + B — maximum alloying

Processability

Cutting primarily by plasma
Limited bending — large radius
Welding with 200–250 °C preheat

Shredder knives, crusher armor plates, screen elements, most loaded bucket parts.

Recommended exclusively for extreme abrasive wear components. Preheat 200–250 °C is mandatory.
