Industry Trends & Demand for Chromium Carbide Liner Solutions

According to MarketsandMarkets, the global wear-resistant steel market is projected to reach USD 17.2 Billion by 2027, with chromium carbide liners driving a substantial share due to their exceptional boundary-layer hardness (up to 65 HRC) and cost-saving maintenance cycles.
Increasing demand across petrochemical, mining, cement, steel, and water management sectors is attributed to:

• Rapid equipment replacement cost reduction (up to 300% lifecycle extension over manganese plate/steel)
• Superior fit for corrosive, highly-abrasive process lines
• Compliance with stringent ISO, ANSI, and DIN material standards

What is a Chromium Carbide Liner?

A chromium carbide liner is a composite plate, typically manufactured by overlay-welding a high-hardness chromium carbide alloy onto a steel substrate, resulting in a wear layer of complex Cr-C carbides in a robust matrix. Compared to conventional manganese plate and manganese steel (e.g., Hadfield Steel, ASTM A128), the carbide layer offers:

• Significantly higher surface hardness (usually 58–65 HRC)
• Excellent abrasion & impact resistance
• Enhanced corrosion resistance via increased chromium content (25–35%)
• Optimization via silico manganese or silicon manganese for improved toughness and weldability
