Plates with a Brinell Hardness Number (BHN) of 400 are exceptionally tough and resistant to wear, making them ideal for various uses. Plates with a BHN of 400 have the following wear resistance and durability characteristics in comparison to plates with lower and higher BHN values:
- Wear Resistance: Plates with a BHN rating of 400 have superior wear resistance than those with lower BHN ratings. 400 BHN plates are more resistant to wear from abrasive materials like stones, rocks, and other similar substances due to their increased hardness. Plates of this hardness are more resistant to wear from sliding and impact than those of lower hardness.
- Durability: Plates with a 400 Brinell Hardness (BHN) hardness last longer and are less likely to crack, dent, or otherwise become deformed than softer materials. As a result, they can be used in situations where the plates will be subjected to stress and wear over time.
- Impact Resistance: Although plates with a 400 BHN rating are among the best available for wear resistance, they may have a somewhat lower impact resistance than plates with a rating of 300 BHN or lower. The trade-off between hardness and toughness and impact resistance is typically quite considerable. Other plate materials with a balance of hardness and toughness may be better-suitable in applications where both high wear and impact resistance are essential.
- Machinability: Plates with lower BHN values are typically easier to machine than plates with a higher BHN value, such as 400 BHN, which can be difficult to machine due to its greater hardness. Machining 400 plates may necessitate using specific tools and processes to produce the appropriate forms and dimensions.
- Weight and Cost: Plates with a BHN of 400 could be thicker and heavier than those with lower BHN values. Materials with greater hardness are typically more expensive because they require more labor-intensive processing and often more expensive alloying components.
- Operating Conditions: Considering the operating conditions when deciding between 400 BHN plates and plates with lower or higher BHN values is essential. Plates with a hardness of 400 BHN Steel Plates are often used in industries where wear resistance is paramount, such as mining, construction, and material handling. Plates of varying hardnesses can be chosen depending on whether impact resistance or machinability is the priority.
The final deciding factor in choosing plate material with the correct BHN value is the needs and constraints of the application. The best plate material for optimal performance and durability can be determined by considering the operating environment, loading parameters, and wear variables.
