588 A572 鉄鋼会社
A588 vs A572 steel:
-
A588 – Weathering steel, naturally forms a protective rust layer, ideal for outdoor, 建築的, and landscaping applications.
-
A572 – High-strength structural steel, optimized for load-bearing projects, requires painting or coating outdoors.
泰達江華, と 20 years of expertise in Corten steel export, offers both A588 and A572 steel plates とともに professional processing for garden and landscape projects such as tree grates, プランター, and outdoor structures.

This guide highlights the differences between A588 and A572 steel and the advantages of working with Teda Ganghua.
1. 化学組成の比較
| 要素 | A588 耐候性鋼 | A572 High-Strength Structural Steel | 主な違い |
|---|---|---|---|
| 炭素 (C) | ≤ 0.23% | ≤ 0.23% | Similar carbon content |
| マンガン (ん) | 0.80-1.50% | 0.85–1.35% | Slightly higher in A572 for strength |
| リン (P) | 0.025–0.040% | 0.04% 最大 | Lower in A588 to enhance protective rust layer |
| 硫黄 (S) | ≤ 0.040% | ≤ 0.05% | 似ている |
| シリコン (そして) | 0.15–0.35% | 0.15–0.40% | Comparable |
| 銅 (銅) | 0.25–0.55% | ≤ 0.20% | Added in A588 for corrosion resistance |
| クロム (Cr) | 0.40% | — | A588 forms stable rust layer; A572 does not |
| ニッケル (で) | 0.65% | — | A588 offers enhanced toughness |
Observation:
-
A588 です 耐候性鋼, designed to develop a stable rust layer outdoors.
-
A572 です high-strength structural steel, designed for load-bearing applications but requires protective coating outdoors.
2. 機械的特性の比較
| 財産 | A588 | A572 (Grade 50–65) | Difference |
|---|---|---|---|
| 降伏強さ (MPa) | 345–470 | 345–450 | Similar strength range |
| 抗張力 (MPa) | 485–630 | 450–620 | Comparable |
| 伸長 (%) | ≥ 20 | 18–22 | Slightly higher in A588 for ductility |
| 耐食性 | Excellent outdoors | 低い; needs painting | A588 suitable for atmospheric exposure |
重要な洞察:
-
A588 excels in weathering environments due to its alloying elements (銅, Cr, で).
-
A572 is preferred for structural projects requiring high strength but not exposed to the elements without coating.
3. Applications Comparison
| Steel Type | 代表的な用途 |
|---|---|
| A588 | 橋, architectural façades, landscaping structures, outdoor sculptures, プランター, tree grates |
| A572 | Structural beams, 列, 産業用フレーム, 建設機械, 重機 |
