Abrasion Resistant Metals
The price differences between abrasion resistant metals are influenced by:
-
Grade and chemical composition
-
Hardness and wear resistance
-
Origin and brand premium
-
Spessore, size, and processing methods
-
Market supply and demand
Choosing the right grade requires balancing cost, prestazione, and application requirements.
Chinese grades like NM500, Mn13, and CrC offer competitive prices with high performance, while international brands provide premium quality and certification guarantees.
- Descrizione
Abrasion resistant metals are specially designed materials that withstand extreme wear, impatto, and abrasive conditions.
They are widely used in minerario, cemento, metallurgia, costruzione, e macchinari pesanti industrie.
The price of these metals varies widely depending on grado, durezza, composizione chimica, spessore, and origin.
1. Common Grades and Typical Price Factors
| Grado / Tipo | Durezza (HB) | Composition Highlights | Price Factor |
|---|---|---|---|
| NM400 / NM450 / NM500 / NM550 / NM600 (Cina) | HB400–600 | Balanced hardness and ductility | Ampiamente disponibile, conveniente, popular in domestic markets |
| Mn13 / Mn18 / Mn22 (Cina & International) | HB180–220 | High-manganese steel, high impact toughness | Specialized alloy, higher production cost due to manganese content |
| Hardox 400 / 450 / 500 / 600 (Svezia) | HB400–600 | High-quality wear-resistant steel | Brand premium, imported, certified quality |
| AR400 / AR500 (USA) | HB400–500 | Abrasion-resistant alloy, elevata durezza | Imported, limited local availability, certification adds cost |
| CrC / CCO (Chrome Carbide Overlay) | HB600–700 | Chromium-carbide hardfacing layer | Expensive due to overlay welding, raw materials, and labor-intensive production |
2. Key Reasons for Price Differences
-
Composizione chimica:
-
Grades with higher alloy content (Cr, In, Mn, Mo) cost more due to expensive raw materials.
-
High-manganese steels and chrome-carbide overlays are significantly more expensive than standard NM grades.
-
-
Hardness and Wear Resistance:
-
Higher HB hardness means better abrasion resistance, which increases production cost.
-
Hardox 600 or CCO plates are designed for extreme conditions, justifying a higher price.
-
-
Origin and Brand:
-
Imported steels (Svezia, USA, EU) carry brand premiums, shipping costs, and certification fees.
-
Domestic Chinese steels are conveniente but still meet industrial requirements.
-
-
Thickness and Size:
-
Thicker plates require more material and energy to produce, increasing cost.
-
Larger sheets or custom sizes may have additional processing costs.
-
-
Processing and Surface Treatment:
-
Overlays, heat treatment, or precision machining add to the price.
-
Rivestimento duro, rolling, or laser cutting requires specialized equipment and labor.
-
-
Supply and Demand / Market Factors:
-
Prices fluctuate based on steel market conditions, global raw material prices, and production capacity.
-
3. Practical Implications for Buyers
-
Per general industrial applications, NM400–NM500 O Mn13 may provide the best balance of cost and performance.
-
Per extreme wear conditions, such as mining or heavy-duty crushers, Hardox 600, AR500, or CrC overlays are recommended despite the higher price.
-
Always consider total cost of ownership: higher upfront price may reduce maintenance and replacement costs.
