AR400 vs. AR500 Steel Plates
AR400 and AR500 are two common wear-resistant steel plates, mainly used in industrial and engineering applications that require high wear resistance.
●AR400: It is a medium-hardness wear-resistant steel plate with a Brinell hardness of 360-440 HBW. It is suitable for occasions with moderate impact and wear.
●AR500: It is a higher hardness wear-resistant steel plate with a Brinell hardness of 460-544 HBW. It is more wear-resistant than AR400 and is suitable for high-impact and high-wear environments.
Chemical composition
Steel plate type | C | Mn | Si | S |
AR400 | 0.30-0.40 | 1.0-1.5 | 0.25-0.50 | ≤0.025 |
AR500 | 0.35-0.50 | 1.0-1.7 | 0.25-0.50 | ≤0.025 |
Comparison of mechanical properties
Performance properties | AR400 | AR500 |
Hardness (HBW) | 360-440 | 460-544 |
Tensile strength | Medium | High |
Ductility | Good | Poor due to higher hardness |
Impact resistance | Suitable for medium impact | Suitable for high impact and high wear |
Comparison of advantages and disadvantages
Features | AR400 | AR500 |
Abrasion resistance | High | Very high |
Ductility | Higher | Low |
Processability | Easy to cut and weld | Difficult to process, requires professional tools |
Applicable environment | Medium impact and wear scenarios | High impact, high wear scenarios |
Cost | Low | High |
Both AR400 and AR500 steel plates are materials with high wear resistance and hardness, but their application ranges are different. AR400 has high toughness and processing convenience, and is suitable for medium wear environments; while AR500 is widely used in extreme wear environments due to its higher hardness and wear resistance.
