Mechanical Properties of NM400
Before selecting, it is crucial to know the mechanical characteristics of NM400:
| Property | Value |
|---|---|
| Hardness | 360 – 440 HBW |
| Yield Strength | ≥ 400 MPa |
| Tensile Strength | 950 – 1100 MPa |
| Elongation | ≥ 12% |
Consider the Chemical Composition of NM400
The chemical composition determines wear resistance and weldability:
| Element | Content (%) |
|---|---|
| C (Carbon) | 0.12 – 0.20 |
| Mn (Manganese) | 1.20 – 1.70 |
| Si (Silicon) | 0.80 – 1.20 |
| P (Phosphorus) | ≤ 0.025 |
| S (Sulfur) | ≤ 0.015 |
| Cr / Ni | ≤ 0.30 |
Application of NM400
NM400 is suitable for moderate-to-heavy wear applications. Typical applications include:
Mining buckets, chutes, and hoppers
Construction machinery blades and wear parts
Crusher liners and conveyor components
Dump truck beds and heavy-duty trailers
For extremely abrasive or high-impact applications, you may consider NM450 or NM500 instead of NM400.
Evaluate Plate Thickness and Size of NM400
NM400 steel plates are available in different thicknesses to match equipment requirements:
| Thickness | Width | Length |
|---|---|---|
| 4 – 25 mm | 1000 – 2500 mm | 2000 – 12000 mm |
Pro tip: Thicker plates increase durability but may require specialized welding and forming techniques.
When selecting NM400 steel plates, focus on:
- Mechanical properties that match your wear and impact needs
- Chemical composition for weldability and toughness
- Plate thickness suitable for your equipment
- Supplier reliability to ensure consistent quality

What is NM400 steel?
NM400 Steel is a high-strength, wear-resistant steel known for its superior durability and toughness. NM400 is a Chinese GB standard steel grade. The NM 400 material is widely used in industries where resistance to abrasion is important, such as in the construction and mining sectors.
What is the difference between Hardox 400 and NM400?
Hardox 400 generally contains a higher chromium (Cr) and nickel (Ni) content, which contributes to better hardness and toughness, while NM400 maintains a balance between cost and performance.
What is the difference between AR 400 and NM400?
NM400 offers cost-effectiveness and low-temperature toughness, making it ideal for budget-conscious projects in moderate wear environments. AR400, with its superior impact resistance and formability, excels in high-impact applications requiring complex fabrication.
Can NM400 be reheated or heat-treated during processing?
This is one of the most critical warnings for first-time users.
NM400 steel plate must not undergo secondary high-temperature heat treatment. The material achieves its wear resistance through a quenched and tempered (Q+T) process. If reheated to high temperatures-such as flame heating for easier bending-the internal microstructure will be altered, resulting in a permanent loss of hardness and wear resistance.
Additionally, the recommended service temperature for NM400 is generally below 250°C–300°C. Exceeding this range may reduce its mechanical properties unless specially alloyed grades (with elements like Mo or V) are used.
