Industeel CREUSABRO® M Wear Resistant Steel Product Information -:- For detailed product information, please contact sales. -: # **Industeel CREUSABRO® M Wear Resistant Steel** ## **Product Overview** Industeel CREUSABRO® M is an advanced family of **thermomechanically rolled, precipitation-hardened** wear-resistant steels designed to deliver an exceptional combination of **ultra-high hardness, superior toughness, and outstanding weldability**. Unlike conventional quenched and tempered (Q&T) abrasion-resistant (AR) steels, CREUSABRO® M employs a unique metallurgical concept combining a fine-grained, tough martensitic matrix with a controlled dispersion of micro-alloyed carbide precipitates. This "Dual Phase" technology results in a product that not only offers superior resistance to abrasive and impact wear but also maintains excellent structural integrity and ease of fabrication, making it a premier choice for the most demanding applications in mining, construction, and material handling. ## **Key Features & Benefits** * **Unmatched Hardness-Toughness Balance:** The core innovation of CREUSABRO® M lies in its ability to achieve very high surface hardness (up to 500 HBW and beyond) while retaining significantly better impact toughness than conventional AR steels of similar hardness. This dramatically reduces the risk of catastrophic cracking under heavy impact or dynamic loading. * **Exceptional Weldability:** Engineered with low carbon equivalent (CEV) and carefully controlled chemistry, CREUSABRO® M can be welded using standard procedures without preheating in most thicknesses and conditions, a major advantage over traditional high-hardness steels. This minimizes fabrication costs, complexity, and the risk of hydrogen-induced cracking (HIC). * **High Work Hardening Capacity:** Under repeated impact or severe abrasion, the steel's surface exhibits a "self-hardening" effect, where hardness can increase by 15-20%. This work-hardened layer provides extended service life as the surface adapts to become even more resistant to wear. * **Excellent Fatigue Resistance:** The clean, homogeneous microstructure and high toughness contribute to superior fatigue performance under cyclic loading, critical for components like buckets, dump truck bodies, and chutes. * **Available in High Strength Grades:** The range includes grades combining wear resistance with high yield strength (up to 1300 MPa), allowing for lighter, high-performance designs. ## **Product Range & International Standards** The CREUSABRO® M family consists of several grades tailored for different levels of abrasion and impact. While it is a proprietary brand, its properties align with and often exceed the requirements of common international abrasion steel specifications. | Industeel Grade | Nominal Hardness (HBW) | Typical Yield Strength (MPa) | Comparable Standards / Notes | | :--- | :--- | :--- | :--- | | **CREUSABRO® M 400** | 400 | ≥ 1000 | Exceeds **EN 10028-6: S500Q/500QO**, **ASTM A514 Gr. B** (wear aspect) | | **CREUSABRO® M 450** | 450 | ≥ 1100 | Superior alternative to **AR450** plates (with better toughness/weldability). | | **CREUSABRO® M 500** | 500 | ≥ 1200 | Superior alternative to **AR500** plates (with better toughness/weldability). | | **CREUSABRO® M 550** | 550 | ≥ 1300 | High-end grade for extreme abrasion, often replacing quenched cast alloys. | *Note: CREUSABRO® is a registered trademark of Industeel. "M" denotes the metallurgically optimized, thermomechanically rolled series.* ## **Chemical Composition (Typical - % )** The composition is a carefully guarded secret, but the philosophy is based on a low-carbon, high-alloy design with micro-alloying elements (Nb, V, Ti). | Element | Typical Range / Characteristic | Role in CREUSABRO® M | | :--- | :--- | :--- | | **Carbon (C)** | Low (≤ 0.25) | Ensures weldability and toughness. Hardness comes from microstructure and precipitates. | | **Manganese (Mn)** | Medium-High | Solid solution strengthener, aids hardenability. | | **Silicon (Si)** | Low-Medium | Deoxidizer, strengthens ferrite. | | **Chromium (Cr)** | Medium-High | Primary alloy for hardenability, corrosion/oxidation resistance, and carbide formation. | | **Molybdenum (Mo)** | Present | Enhances hardenability, strength at high tempering temperatures. | | **Boron (B)** | Trace (often used) | Dramatically increases hardenability at very low concentrations. | | **Niobium (Nb), Vanadium (V), Titanium (Ti)** | Micro-alloyed | Key to the technology. Form fine carbonitride precipitates during thermomechanical rolling, providing precipitation hardening (strength/hardness) and grain refinement (toughness). | **Carbon Equivalent (CEV):** Deliberately kept very low (e.g., often below 0.50), which is the foundation of its excellent weldability. ## **Physical & Mechanical Properties (Example: CREUSABRO® M 500)** * **Hardness:** **480 - 530 HBW** (Brinell 10/3000). Uniform through thickness. * **Yield Strength (Rp0.2):** **≥ 1200 MPa** * **Tensile Strength (Rm):** **≥ 1400 MPa** * **Elongation (A5):** **≥ 10%** (Remarkable for this hardness level). * **Impact Toughness (Charpy V-notch at -20°C / -40°C):** Typically **≥ 40 J / ≥ 27 J** (Far superior to conventional Q&T AR500). * **Work Hardening Capacity:** Surface hardness can increase to over **600 HBW** under severe impact abrasion. * **Density:** ~7.85 g/cm³ ## **Typical Applications** CREUSABRO® M is specified for critical components subjected to severe wear and high stress: * **Mining & Quarrying:** Bucket liners for excavators and loaders, dump truck body liners, bulldozer blades, wear plates in crushers, screens, and chutes. * **Construction:** Cutting edges, grader blades, conveyor skirting, demolition tooling. * **Material Handling:** High-wear areas in hoppers, silos, feeders, and conveyors. * **Agriculture:** Ploughshares, harrow discs, chipper blades. * **Forestry & Recycling:** Chipper anvils, shredder hammers and liners. ## **Fabrication Guidelines** * **Cutting:** Can be cut by plasma, laser, or waterjet. Oxy-fuel cutting is possible but requires specific procedures to avoid hardening the cut edge. * **Bending & Forming:** Can be cold formed with a bending radius typically 3-5x the plate thickness, depending on grade and orientation. * **Welding (Key Advantage):** * **Preheating:** Generally **NOT REQUIRED** for most thicknesses due to low CEV. For very thick sections (>50mm) or constrained joints, mild preheating (≤100°C) may be advised. * **Filler Metal:** Use low-hydrogen, high-toughness electrodes/wires with a slightly undermatching strength (e.g., ~900 MPa yield strength). Common choices include high-performance wires like OK Aristorod 12.10 or equivalent. * **Procedure:** Standard low-hydrogen practices. Maintain interpass temperature below 250°C. Post-weld heat treatment is not required. * **Machining:** Requires carbide tools, positive rake angles, rigid setups, and adequate cooling. ## **Summary** **Industeel CREUSABRO® M** redefines the performance standard for wear-resistant steels. By moving beyond the limitations of conventional quenched and tempered AR plate, its innovative "Dual Phase" microstructure delivers a previously unattainable synergy of **extreme hardness, exceptional toughness, and unparalleled weldability**. This translates directly into components with longer service life, higher reliability under impact, and significantly lower total cost of ownership due to easier fabrication and reduced downtime. For engineers facing the dual challenges of severe abrasion and structural loading, CREUSABRO® M provides a technologically superior and economically sound solution. -:- For detailed product information, please contact sales. -: Industeel CREUSABRO® M Wear Resistant Steel Specification Dimensions Size： Diameter 20-1000 mm Length <5246 mm Size:We can customized as required Standard： Per your request or drawing We can customized as required Properties（Theoretical） Chemical Composition -:- For detailed product information, please contact sales. -: Industeel CREUSABRO® M Wear Resistant Steel Properties -:- For detailed product information, please contact sales. -:
