NM500 NM600 Abrasion Steel Plate

NM500 NM600 Abrasion Steel Plate

---

NM500 and NM600 are premium abrasion-resistant steel plates designed for heavy-duty applications where wear is a major concern. The key difference lies in hardness and performance level:

 

• NM500: High wear resistance with balanced toughness

NM500 is a high-strength wear-resistant steel plate with high hardness and wear-resistant properties, suitable for manufacturing wear-resistant parts and structural components. Widely used in mining machinery, construction machinery, engineering machinery, agricultural machinery, metallurgical machinery and other fields, for the manufacture of wear-resistant parts and structural components, such as crusher liners, excavator buckets, bulldozer blades, conveying pipelines, etc. The implementation of the standard of NM500 steel plate is GB/T 24186-2009 "High Strength Wear-Resistant Steel Plate for Construction Machinery".

 

• NM600: Ultra-high wear resistance for extreme abrasion

The main chemical composition of NM600 wear-resistant steel plate includes carbon, silicon, manganese, phosphorus, sulfur and other elements. Among them, the carbon content is high, which can improve the hardness and wear resistance of the steel plate. Meanwhile, the addition of silicon, manganese and other elements can further enhance the strength and toughness of the steel plate.

 

At GNEE Steel, we supply NM500 and NM600 plates with consistent hardness, strict quality control, and global export capability.

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.
