Products Description
High strength ASTM A588 steel sheet VS A36 mild steel sheet in strength. ASTM A588 steel is HSLA structural steel , up to 50 KSI minimum yield point, with atmospheric corrosion resistance for applications where strength and durability are needed. A36 mild steel has very good welding properties along with 36 KSI yield strength. A36 steel is considered a mild steel due to hardness.
High strength ASTM A588 steel Plate VS A36 mild steel plate in corrosion resistance. ASTM A588 steel is well known for its weathering ability.
A588 steel has four times as much corrosion resistance as A36 mild steel. When A588 steel is exposed to external conditions, its corrosion-resistant properties become stronger, even when unpainted.
ASTM A36 Steel Plate and ASTM A588 Steel Plate are two different specifications for steel used in various applications. Here are the key differences between ASTM A36 Steel Plate and ASTM A588 Rusty Steel Plate:
Composition
ASTM A36 Steel Plate: It is a low carbon steel that typically contains up to 0.29% carbon, along with manganese, phosphorus, sulfur, silicon, and copper as residual elements.
ASTM A588 Hot Rolled Corten Steel Plate: It is a high-strength, low-alloy structural steel that primarily consists of iron, chromium, nickel, and copper as alloying elements.
| Property / Element | A588 (Grade B) | A36 Steel |
|---|---|---|
| Carbon (C) | ≤0.26% | ≤0.26% |
| Manganese (Mn) | 0.80–1.25% | 0.60–0.90% |
| Phosphorus (P) | ≤0.04% | ≤0.04% |
| Sulfur (S) | ≤0.05% | ≤0.05% |
| Copper (Cu) | 0.20–0.40% | 0–0.20% |
| Chromium (Cr) | 0.40% max | – |
| Nickel (Ni) | 0.40% max | – |
| Tensile Strength | 485–620 MPa | 400–550 MPa |
| Yield Strength | 345 MPa min | 250 MPa min |
| Elongation (in 8") | ≥20% | ≥20% |
Strength and Mechanical Properties
ASTM A36 Steel Plate: It has a minimum yield strength of 250 megapascals (MPa) and a minimum tensile strength of 400 MPa. It exhibits good ductility and can be easily machined, welded, and formed.
ASTM A588 Weathering Steel Plate : It offers higher strength compared to ASTM A36, with a minimum yield strength of 345 MPa and a minimum tensile strength of 485 MPa. It provides excellent atmospheric corrosion resistance due to its composition.
Applications
ASTM A36 Steel Plate: It is widely used in general structural applications such as buildings, bridges, and machinery parts.
ASTM A588 Corten Steel Plate: It is commonly used for outdoor structures exposed to the elements, including bridges, buildings, transmission towers, and freight cars.
It's important to note that these differences highlight the contrasting characteristics of ASTM A36 and ASTM A588. When selecting the appropriate steel grade for a specific application, it is crucial to consider the project requirements, environmental conditions, and consult with professionals or steel suppliers for accurate material selection.
