KmTBCr26 Wear Resistant Cast Iron

Extreme abrasion resistance for mining, cement, power generation and heavy-duty material handling systems.

Hardness up to HRC 65
High chromium M₇C₃ carbides
Long service life under severe abrasion

KmTBCr26 is a high chromium white cast iron specifically engineered for components exposed to intense abrasive wear.

Extreme Hardness

The microstructure is dominated by hard chromium carbides, delivering outstanding resistance to sliding and impact abrasion.

Designed for Wear, Not Deformation

Optimized for wear resistance rather than ductility, making it ideal for liners, plates and wear blocks.

Lower Cost per Ton Handled

Longer service life reduces replacement frequency and downtime, significantly lowering total operating cost.

Why Choose ZG35Cr24Ni7SiN?

ZG35Cr24Ni7SiN is a high-performance heat-resistant cast alloy engineered for extreme thermal environments. It offers exceptional durability, oxidation resistance, and cost efficiency—making it the smart choice for demanding high-temperature applications.

Extended Service Life at High Temperatures

Designed for continuous operation up to 1050°C, ZG35Cr24Ni7SiN maintains structural stability and mechanical strength even under prolonged thermal exposure.

Excellent Oxidation & Scaling Resistance

High chromium and silicon content form a dense, protective oxide layer that significantly reduces metal loss and extends maintenance intervals.

Stronger at Temperature, Not Just at Room Conditions

Nitrogen alloying dramatically improves creep resistance and high-temperature strength, outperforming conventional Cr–Ni cast steels during long-term service.

Cost-Effective Alternative to High-Nickel Alloys

Delivers performance comparable to high-Ni grades like ZG40Cr25Ni20 in many applications—at a significantly lower alloy cost.

Ideal for Complex Cast Components

Superior castability enables production of large, intricate one-piece components—reducing welds, joints, and potential failure points.

Material Comparison

Selecting the right wear material is critical for service life and operating cost. Below is a practical comparison of common wear-resistant materials.

Material	Typical Hardness	Wear Resistance	Impact Resistance	Service Temperature	Cost Level	Typical Applications
KmTBCr26	HRC 58–65	★★★★★	★★	≤ 500°C	★★★	Severe abrasion liners, chutes, wear plates, mining & cement equipment
Ni-Hard (Ni-Hard 4)	HRC 55–60	★★★★	★★★	≤ 400°C	★★★	Impact + abrasion parts, mill liners, crusher components
Cr20 Cast Iron	HRC 50–58	★★★☆	★★☆	≤ 450°C	★★	Medium abrasion conditions, general wear parts
Hardfacing Overlay	HRC 55–62	★★★★☆	★★★	≤ 600°C*	★★★★	Local wear protection, repair and reinforcement

Engineering Tip: KmTBCr26 is recommended when abrasion is the dominant wear mechanism and maximum service life is required. For high impact or on-site repair, Ni-Hard or hardfacing solutions may be more suitable.
