NM600 Wear-Resistant Steel Plate Metal
NM600 wear-resistant steel is wear-resistant, heat-resistant and robust. It is designed for extensive wear conditions. Due to the perpendicular distribution of carbides along the wear direction, the wear resistance is more than doubled, even when compared to cast alloys of the same composition and hardness. The substrate of the wear-resistant composite steel plate is low carbon or low alloy steel. Toughness materials such as stainless steel reflect the superiority of bimetallic to withstand the impact and abrasion of high drop hoppers in material handling systems.NM600 Wear Resistant Steel Plate has the advantages of high abrasion resistance, good impact performance, good temperature resistance, and good connection performance.
The designation "NM" derives from the Chinese pinyin initials of "wear resistance" (Nai Mo), while the "600" indicates the nominal Brinell hardness of the steel plate, typically ranging from 570 to 640 HBW. Manufactured through advanced quenching and tempering processes, NM600 achieves a perfect balance of ultra-high hardness, strength, and toughness, making it suitable for welded fabrications and heavy-duty assemblies without sacrificing performance.
The chemical composition of the alloy wear-resistant layer has a carbon content of 4 to 5 per cent and a chromium content of 25 to 30 per cent. The hardness is HV1400-1800. due to the linear distribution of carbides in the direction of wear, the wear resistance of NM600 wear resistant plate is more than twice as high as that of casting alloys of the same composition and hardness.

Core Features & Advantages of NM600
Exceptional Wear Resistance
NM600 boasts superior abrasion resistance, thanks to its optimized alloy composition and fine-grained martensitic microstructure achieved through precise heat treatment. The steel contains high levels of carbide-forming elements (such as chromium), with carbide volume fractions exceeding 50%, resulting in a surface hardness of 570-640 HBW – significantly higher than standard steel plates. This translates to 3-5 times the wear life of conventional steel, effectively withstanding abrasion from ore, gravel, and other harsh materials in extreme working conditions.
Balanced Strength & Toughness
Unlike brittle high-hardness steels, NM600 maintains excellent toughness while delivering ultra-high strength. It features a tensile strength of 1400-1600 MPa, yield strength of ≥1200 MPa, and elongation of ≥8%, with impact energy absorption of ≥18 J at -40℃. This balance ensures the steel can absorb impact loads without cracking, making it suitable for high-impact wear scenarios such as mining and construction machinery applications.
Superior Machinability & Weldability
Despite its ultra-high hardness, NM600 retains good machinability and weldability when processed with proper techniques. It can be cut (flame, plasma, laser), drilled, bent, and welded, with preheating and post-weld heat treatment recommended to prevent cracking. This flexibility allows for easy customization and integration into various equipment and structures, reducing processing time and costs.
Strict Quality Control
Every batch of NM600 steel plate undergoes rigorous quality testing in accordance with GB/T 24186-2009 standards, ensuring consistent performance and reliability. Testing items include chemical composition analysis, mechanical property verification, hardness mapping, and ultrasonic inspection. We provide complete mill test certificates and third-party inspection services to guarantee compliance with international standards.
NM600 wear resistant metal Products Details
The production process of NM600 wear-resistant steel plate mainly includes smelting, continuous casting, rolling and heat treatment. In the smelting process, the use of vacuum induction furnace for melting, to ensure the purity of steel. Continuous casting process, the use of continuous casting machine will cast steel into slabs. In the rolling process, the rolling mill is used to roll the slab into the required thickness and width. Finally, through the heat treatment process, the internal organisation of the steel plate is adjusted to improve its mechanical properties and wear resistance.

Case : Steel Plates Supply for 100,000m³ Full Containment Ammonia Storage Tank Project
GNEE STEEL is currently participating in the procurement phase of a 100,000m³ full containment ammonia storage tank project, supplying high-quality steel plates for critical tank components. Due to the corrosive nature of ammonia and the risk of Ammonia Stress Corrosion Cracking (SCC), the project requires strict metallurgical control of materials according to EN 10028-3 standards.
One of the most important technical requirements of this project is the strict limitation of the actual Yield Strength (Re) for all NL2 grade materials. To prevent SCC risks in ammonia storage environments, the actual yield strength must not exceed 390 MPa, regardless of the nominal values specified in the standard or plate thickness ranges. This requirement places higher demands on steelmaking process control, heat treatment stability, and material testing.
Raw high-strength steel plates ready for the 100,000 m³ full containment ammonia storage tank production
Project Materials and Technical Requirements
The project mainly uses P355NL2 and P275NL2 normalized pressure vessel steel plates, which are widely applied in low-temperature storage tanks due to their excellent toughness and weldability.
Key technical specifications include:
- Material grades: P355NL2 and P275NL2 (Normalized)
- Yield strength: Standard minimum / Maximum limited to 390 MPa
- Hardness: ≤ 225 HBW in base material
- Impact testing: Charpy-V notch test at -50°C, minimum 27J
- Certification: EN 10204 3.1 certificate, with optional 3.2 certification
These strict requirements ensure that the steel plates maintain stable mechanical properties and high resistance to ammonia-induced stress corrosion during long-term operation.
Precision rolling and forming of steel plates into curved sections for the 100,000 m³ ammonia storage tank.
Project Plate Quantities and Thickness Distribution
The total steel demand for this ammonia storage tank project is several thousand tons, mainly distributed across different tank sections:
P355NL2 – Inner & Outer Tank Shell Plates
- Lower shell courses: 50 mm thickness – approx. 2,000 tons
- Middle shell courses: 25 mm thickness – approx. 1,400 tons
- Upper shell courses: 10 mm thickness – approx. 500 tons
P275NL2 – Tank Bottom Plates
- Thickness: 10–15 mm – approx. 750 tons
P275NL2 – Suspended Roof Structure
- Thickness: 5–8 mm – approx. 180 tons
S275JR – Outer Roof (Ambient Structure)
- Thickness: 10 mm – approx. 450 tons
To improve tank fabrication efficiency and reduce circumferential welds, the project also requires wide steel plates to minimize welding joints, which helps reduce the potential risk of SCC in ammonia service conditions.
Formed steel segments wrapped and racked for protection, ready for 100,000 m³ ammonia storage tank assembly.
