-
ARシリーズ そして Chinese NM series は 機能的に同等 in terms of 硬度, 耐摩耗性, および産業用途.
-
NM series provides a cost-effective alternative for industrial users while maintaining comparable chemical composition and mechanical properties.
-
Selecting the right grade depends on application requirements, 厚さ, and availability, but either series can meet high-abrasion industrial needs.
- 説明
AR (耐摩耗性) プレートを着用してください are high-hardness steels designed to withstand extreme wear and impact.
中国では, the equivalent series is the ニューメキシコ州 (耐摩耗性) series, which includes NM400, NM450, NM500, NM550, and NM600.
While both series serve similar purposes, there are differences in 化学組成, 硬度, and mechanical performance.
1. 化学組成の比較
| 学年 | C (%) | ん (%) | Cr (%) | モー (%) | その他 |
|---|---|---|---|---|---|
| AR400 | 0.2–0.25 | 1.2-1.5 | 0.8-1.2 | 0.2-0.3 | ~0.3で |
| AR450 | 0.25-0.3 | 1.4–1.7 | 0.8–1.3 | 0.2-0.3 | ~0.3で |
| AR500 | 0.3–0.4 | 1.4–1.8 | 0.9-1.5 | 0.2–0.4 | ~0.3で |
| NM400 | 0.18–0.22 | 1.2-1.5 | 0.8-1.1 | 0.15–0.25 | — |
| NM450 | 0.22–0.26 | 1.3-1.6 | 0.8-1.2 | 0.2-0.3 | — |
| NM500 | 0.25–0.32 | 1.4–1.7 | 0.9–1.3 | 0.2–0.35 | — |
観察:
-
Both AR and NM series contain 炭素, マンガン, とクロム as key alloying elements.
-
AR series may include nickel and slightly higher alloy contents for imported quality control.
-
Chinese NM series is produced to ギガバイト/トン 24186 標準, ensuring comparable hardness and wear resistance.
2. Mechanical Performance Comparison
| 学年 | 硬度 (HB) | 抗張力 (MPa) | 降伏強さ (MPa) | 衝撃靱性 (j) |
|---|---|---|---|---|
| AR400 | 400 ± 20 | 850–950 | 550–700 | 25–35 |
| AR450 | 445–475 | 900–1000 | 600–750 | 25–40 |
| AR500 | 500 ± 20 | 950–1100 | 650–800 | 20–35 |
| NM400 | 400 ± 20 | 850–950 | 550–700 | 25–35 |
| NM450 | 440–460 | 900–1000 | 600–750 | 25–40 |
| NM500 | 480–520 | 950–1100 | 650–800 | 20–35 |
重要なポイント:
-
Hardness and tensile properties are very similar between AR and NM grades.
-
Both series are suitable for heavy wear applications.
-
Slight differences may exist due to raw material sources and heat treatment processes.
