Wear resistant steel equipment lives or dies by the Brinell grade you pick. Too soft and the liner wears in months. Too hard and it cracks under impact. Consequently, equipment manufacturers match the hardness to the failure mode. Here are the common equipment components and the grades that fit.

Equipment Component vs Brinell Grade

Component	Failure mode	Recommended grade
Chute liner	Sliding abrasion	400HB
Bucket liner	Impact + abrasion	500HB
Hopper plate	Gravity abrasion	400HB
Crusher jaw	High impact	500HB–600HB
Dump bed liner	Impact + rock	450HB
Auger flight	Fine abrasion	400HB

Case 1: Chute Liner

A copper mine chute handled 500 t/h of crushed ore. Mild steel liner wore out in 3 months. Consequently, the plant switched to 400HB Wear Resistant Steel Plate. The new liner lasted 18 months. Furthermore, replacement downtime dropped by 75%.

Case 2: Excavator Bucket

A quarry bucket loaded blasted rock. Mild steel wore through in 6 months. Furthermore, impact cracks formed at the welds. Consequently, the shop installed 500HB Wear Resistant Steel Plate as a bolt-on liner. The liner lasted 24 months and swapped out in hours.

Case 3: Crusher Liner

Crushers see both impact and grinding. Consequently, they need the hardest grade we stock. 500HB–600HB plate handles repeated rock impact without cracking. Furthermore, it stays hard through the working life.

Why Harder Is Not Always Better

Harder plate lasts longer in pure abrasion. However, it also cracks under severe impact. Consequently:

• Sliding abrasion (chutes, hoppers): 400HB works.
• Impact + abrasion (buckets, crushers): 500HB works.
• Pure impact only: use manganese steel, not through-hardened plate.

Cut to Size, Not Full Sheets

Equipment manufacturers do not want full 2000 × 6000 mm sheets. Consequently, we cut liners to your drawing with 2 mm welding stock. Furthermore, we ship with MTC and Brinell hardness report.

Specify Your Wear Part

Tell us:

1. What material flows (rock, ore, sand, cement).
2. Impact level (low, medium, high).
3. Required liner thickness and dimensions.
4. Welding or bolt-on installation.

We will recommend the correct Brinell grade and quote.
