588 Entreprise sidérurgique A572
A588 vs A572 steel:
-
A588 – Weathering steel, naturally forms a protective rust layer, ideal for outdoor, architectural, and landscaping applications.
-
A572 – High-strength structural steel, optimized for load-bearing projects, requires painting or coating outdoors.
Teda Ganghua, avec 20 years of expertise in Corten steel export, offers both A588 and A572 steel plates avec traitement professionnel for garden and landscape projects such as grilles d'arbre, jardinières, et structures extérieures.

This guide highlights the differences between A588 and A572 steel and the advantages of working with Teda Ganghua.
1. Comparaison de la composition chimique
| Élément | Acier patinable A588 | A572 High-Strength Structural Steel | Différence clé |
|---|---|---|---|
| Carbone (C) | ≤ 0.23% | ≤ 0.23% | Similar carbon content |
| Manganèse (Mn) | 0.80–1,50% | 0.85–1.35% | Slightly higher in A572 for strength |
| Phosphore (P.) | 0.025–0.040% | 0.04% maximum | Lower in A588 to enhance protective rust layer |
| Soufre (S) | ≤ 0.040% | ≤ 0.05% | Similaire |
| Silicium (Et) | 0.15–0.35% | 0.15–0.40% | Comparable |
| Cuivre (Cu) | 0.25–0.55% | ≤ 0.20% | Added in A588 for corrosion resistance |
| Chrome (Cr) | 0.40% | — | A588 forms stable rust layer; A572 does not |
| Nickel (Dans) | 0.65% | — | A588 offers enhanced toughness |
Observation:
-
A588 est un acier patinable, designed to develop a stable rust layer outdoors.
-
A572 est un acier de construction à haute résistance, designed for load-bearing applications but requires protective coating outdoors.
2. Comparaison des propriétés mécaniques
| Propriété | A588 | A572 (Grade 50–65) | Difference |
|---|---|---|---|
| Limite d'élasticité (MPa) | 345–470 | 345–450 | Similar strength range |
| Résistance à la traction (MPa) | 485–630 | 450–620 | Comparable |
| Élongation (%) | ≥ 20 | 18–22 | Slightly higher in A588 for ductility |
| Résistance à la corrosion | Excellent outdoors | Faible; needs painting | A588 suitable for atmospheric exposure |
Aperçu clé:
-
A588 excelle dans weathering environments due to its alloying elements (Cu, Cr, Dans).
-
A572 is preferred for structural projects requiring high strength but not exposed to the elements without coating.
3. Applications Comparison
| Type d'acier | Applications typiques |
|---|---|
| A588 | Ponts, façades architecturales, landscaping structures, sculptures extérieures, jardinières, grilles d'arbre |
| A572 | Structural beams, colonnes, cadres industriels, engins de chantier, matériel lourd |
