nm400 is an alloy steel plate with high hardness, high strength and high toughness. It has good corrosion resistance and oxidation resistance; at the same time, its work hardening phenomenon is much smaller than that of low carbon steel (the increase in strength and toughness is negligible); it has good anti-tempering stability and good mechanical properties, etc. properties, so it has a wide range of applications.
Nm 400 wear-resistant steel plate is a plate product with a thickness of 0.4-2.0mm. It is mainly used for various purposes in the metallurgical industry: such as being used to make hot rolling roller bearing blanks or directly used after quenching. It can be used as product parts; it can also be used as the inner wall lining of oil tanks in the heat treatment state. In addition, it can also be used as a material for manufacturing cutting tools, gauges, templates, etc. Due to its stable chemical composition and good mechanical properties, this product is widely used in the mining equipment manufacturing industry due to its long service life and other advantages.
The grade of nm-400 is AISI 410D/E /F, which is carbon tool structural steel (CW-4).
1. Characteristics and scope of application
(1) Good cold forming performance and welding performance.
(2) High hardness and wear resistance
(3) Excellent stamping formability and high fatigue
(4) Low Notch sensitivity
2. Technical requirements
1) The steel should be agreed between the supplier and the buyer and comply with the following regulations:
a) The steel grade should not be less than AISi B 380M ;
b) C Si Mn P s≤ 0.30-0.60%;
c) Mn≥ 1.50%, Cr ≤ 2.00% (mass fraction).
2) When inspecting according to the above standards, the impact test should be carried out at room temperature. When lamellar separation occurs on the fracture surface of the sample, the Brinell method can be used to check the defect level.
3) Ultrasonic testing and analysis can be carried out according to the needs of the buyer.
4. Delivery status
Castings produced from semi-finished products with annealing heat treatment or unnormalized homogenization treatment are called forging blanks, which generally must go through the forging process. Then make the products into shapes and sizes.
We also provide forging blanks and CNC precision machining services for our clients, covering industries such as energy, petrochemicals, steel, engineering machinery, plastics, prevention and control, hydraulics, healthcare, and food. Please feel free to send us drawings for inquiries.

Our heavy-duty forging presses support open-die forging and deformation of large-section forgings, including discs, shafts, blocks, and custom components. This capability enables us to meet the demanding forming requirements of heavy industrial applications.
Heat treatment is a critical step in achieving the mechanical properties required for heavy-duty forgings. Our process capabilities meet the strength, toughness, and structural stability requirements for forged components used under demanding operating conditions.
We offer machining capabilities for large forged shafts and long cylindrical components, supporting both rough and finish machining. This capacity is suitable for stepped shafts, rotor shafts, rollers, and other heavy-duty forged shaft components.
Our machining facilities are capable of handling large ring-shaped forgings and circular parts that require precise turning, face machining, boring, and contour control. This capability is suitable for industrial ring blanks, heavy-duty circular parts, and machined ring forgings.
We offer machining solutions for heavy-duty cylindrical, hollow, and tubular forgings. This capability supports the machining of sleeves, cylinders, and other thick-walled forged components used in pressure vessels, rotating systems, and general industrial applications.
Quality control is integrated into our production process through the inspection and testing of forged and machined parts. Our capabilities help verify the dimensional accuracy, condition, and quality consistency of industrial forgings prior to delivery.
Finished forgings are properly protected and packaged to minimize the risk of damage during storage and transportation. Our packaging methods ensure the safe domestic delivery and export shipment of machined and high-value forged components.
