NM360 NM400 NM450 Wear Steel Plate
NM360 wear-resistant steel plate is a kind of wear-resistant steel plate with high strength, high hardness, high abrasion resistance, medium toughness, etc. It is mainly used to manufacture various important mechanical parts, such as gears, sprockets, propellers, transmission shafts, pistons, seals and so on.
NM400 abrasion resistant steel plate has quite high mechanical strength, and its mechanical properties are 3 times to 5 times that of ordinary low alloy steel plate, which can significantly improve the wear resistance of machinery-related parts, and therefore improve the service life of machinery and reduce production costs.
NM450 wear plate, NM means wear-resistant, 450 means the average Brinell hardness is around 450.NM450 is widely used in metallurgical industry, road building industry, sand mill cylinder, blade, U-type dump trucks, all kinds of cargo yard, dock machinery parts, bearing structural parts, railway wheel structural parts, rolls and so on.

FAQ
What is NM400 steel?
NM400 is a type of wear-resistant steel plate, with a Brinell hardness value of HB. The hardness value of NM400 is broad, ranging from 360 to 420.
What is NM450 steel?
NM450 is a high-strength, wear-resistant steel grade defined under the Chinese GB/T 24186 standard. It is specifically engineered for applications requiring exceptional abrasion resistance, making it ideal for heavy-duty machinery in industries like mining, construction, quarrying, and material handling
What is the difference between Hardox 500 and Hardox 400?
Hardox® 400 usually falls in the range of about 370–430 HBW. Hardox® 450 sits higher, around 425–475 HBW. Hardox® 500 reaches the top end, often between 470–530 HBW. Each step up offers more wear life but less tolerance for impact and forming.

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.
