588 Syarikat Keluli A572
A588 vs A572 steel:
-
A588 – Weathering steel, naturally forms a protective rust layer, ideal for outdoor, seni bina, and landscaping applications.
-
A572 – High-strength structural steel, optimized for load-bearing projects, requires painting or coating outdoors.

1. Perbandingan Komposisi Kimia
| unsur | A588 Keluli Luluhawa | A572 High-Strength Structural Steel | Perbezaan Utama |
|---|---|---|---|
| Karbon (C) | ≤ 0.23% | ≤ 0.23% | Similar carbon content |
| Mangan (Mn) | 0.80–1.50% | 0.85–1.35% | Slightly higher in A572 for strength |
| Fosforus (P) | 0.025–0.040% | 0.04% maks | Lower in A588 to enhance protective rust layer |
| Sulfur (S) | ≤ 0.040% | ≤ 0.05% | serupa |
| silikon (Dan) | 0.15–0.35% | 0.15–0.40% | Comparable |
| Tembaga (Cu) | 0.25–0.55% | ≤ 0.20% | Added in A588 for corrosion resistance |
| Chromium (Cr) | 0.40% | — | A588 forms stable rust layer; A572 does not |
| nikel (Dalam) | 0.65% | — | A588 offers enhanced toughness |
Pemerhatian:
-
A588 ialah a keluli luluhawa, designed to develop a stable rust layer outdoors.
-
A572 ialah a keluli struktur berkekuatan tinggi, designed for load-bearing applications but requires protective coating outdoors.
2. Perbandingan Sifat Mekanikal
| Harta benda | A588 | A572 (Grade 50–65) | Difference |
|---|---|---|---|
| Kekuatan Hasil (MPa) | 345–470 | 345–450 | Similar strength range |
| Kekuatan Tegangan (MPa) | 485–630 | 450–620 | Comparable |
| Pemanjangan (%) | ≥ 20 | 18–22 | Slightly higher in A588 for ductility |
| Rintangan Kakisan | Excellent outdoors | rendah; needs painting | A588 suitable for atmospheric exposure |
Wawasan Utama:
-
A588 cemerlang dalam weathering environments due to its alloying elements (Cu, Cr, Dalam).
-
A572 is preferred for structural projects requiring high strength but not exposed to the elements without coating.
3. Applications Comparison
| Jenis Keluli | Aplikasi Biasa |
|---|---|
| A588 | Jambatan, fasad seni bina, landscaping structures, arca luar, penanam, parut pokok |
| A572 | Structural beams, lajur, industrial frames, jentera pembinaan, alat berat |
