ASTM A830-1020 Steel Plate: High-Quality Low-Carbon Steel for Machining and Structural Applications
Overview:
ASTM A830-1020 steel plate is a low-carbon, highly ductile steel commonly used in machining and manipulation applications. Known for its excellent formability and weldability, this grade of steel is particularly suitable for structural applications requiring moderate strength and good surface finish. It meets ASTM A830 specifications, which outline standards for carbon steel plates intended for general structural and mechanical applications.
Shanxi Luokaiwei Steel Company offers ASTM A830-1020 steel plates in standard and heavy thicknesses (3 inches or greater). Given the high demand and rapid turnover of this steel grade, it is recommended to inquire about availability before placing an order to ensure timely delivery.
Chemical Composition of ASTM A830-1020 Steel Plate
The chemical composition of ASTM A830-1020 steel plate is governed by ASTM A830 specifications, which provide the exact percentage of each element in the steel. The composition ensures that the steel maintains its excellent machinability, weldability, and structural properties.
| Element | ASTM A830-1020 Specification |
|---|---|
| Carbon (C) | 0.18% – 0.23% |
| Manganese (Mn) | 0.30% – 0.60% |
| Phosphorus (P) | ≤ 0.030% |
| Sulfur (S) | ≤ 0.030% |
-
Carbon (C): The low carbon content of A830-1020 (between 0.18% and 0.23%) makes it highly ductile and easy to form.
-
Manganese (Mn): Manganese plays an important role in improving toughness and strength. The content ranges from 0.30% to 0.60%.
-
Phosphorus (P): Phosphorus is kept to a maximum of 0.030% to avoid brittleness and ensure good formability.
-
Sulfur (S): Sulfur is kept at a maximum of 0.030% to prevent sulfur-related defects and to ensure better surface finish during machining.
