Austenitic High Manganese Steel Crusher Parts

Austenitic high manganese steel is the core material for many jaw and cone crusher wear parts because of its toughness and work-hardening ability.

PAJOA supplies common grades such as

  • Mn13Cr2

  • Mn18Cr2

  • Mn22Cr2

for jaw plates, cheek plates, mantles, concaves, and other high-impact wear parts.

Martensitic Alloy Steel Crusher Parts

Martensitic alloy steel is a good choice for medium to high impact + medium abrasion conditions, where standard manganese is too soft but full high chrome may be too brittle.

 

Typical wear parts

  • Impact crusher blow bars for mixed feed (natural stone + some steel content)

  • Crusher hammers and liners in plants with frequent impact and moderate abrasion

  • Other wear parts that need stronger wear resistance than manganese, but still require good toughness to avoid cracking

High Chrome Cast Iron

High chrome cast iron is best for very abrasive, relatively lower-impact working conditions, where the main priority is wear resistance rather than impact toughness.

Typical wear parts

  • Impact crusher blow bars in hard, abrasive stone applications

  • Breaker plates and impact plates in secondary/tertiary crushing

  • Liners and wear blocks in areas exposed to continuous abrasive flow, with limited heavy steel or tramp metal in the feed

Ceramic Inserts and TIC Reinforcement

Ceramic inserts and TIC reinforcement are upgrade options for critical high-wear zones where customers need noticeably longer life than a single-alloy solution can provide. They are especially useful when downtime is expensive or access to the crusher is difficult.

How they are used
These are not separate base materials. Ceramic or TIC bars are inlaid into manganese steel, martensitic steel, or other suitable castings to strengthen the leading wear surfaces while the base material still provides overall support and toughness.

Typical wear parts

  • Blow bars with ceramic or TIC inserts for very abrasive impact crusher applications

  • Jaw plates with TIC inserts for hard, abrasive rock or recycled concrete with rebar

  • Cone crusher liners with reinforced leading edges in high-wear feed zones

  • Hammer heads and other heavy-wear components in demanding, high-throughput lines

Reference chemical composition for martensitic alloy steel with ceramic inserts (ASTM A 983 (7A))

Carbon (C)< 0.60%
Silicon (Si)< 1.00%
Manganese (Mn)< 1.50%
Phosphorus (P)≤ 0.025%
Sulfur (S)≤ 0.025%
Chromium (Cr)2.0–5.5%
Nickel (Ni)< 1.50%
Molybdenum (Mo)< 1.00%
Vanadium (V)≤ 0.10%
Hardness (HRC)52 ± 3

Customized Materials for Your Working Conditions

Custom material solutions are recommended when standard manganese, martensitic, or high chrome options cannot meet the required service life, or when parts are failing by cracking, chipping, or uneven wear.

Share Your Working Conditions

Tell us your crusher model, feed material, abrasiveness, impact level, wear pattern, and target service life.

01

Match the Right Material & Design

We recommend the right base material, reinforcement option, and wear-part structure for your actual application.

02

Deliver a Custom Wear Solution

The result is a more suitable wear part with longer life, more stable performance, and lower cost per ton.
