ASTM F1083 specifies the requirements for welded steel tubes used in fence structures, particularly those that are hot-dipped galvanized. These tubes are designed to provide durability and corrosion resistance, making them ideal for outdoor applications.
The specification covers various nominal pipe sizes (NPS) including NPS1, NPS2, NPS3, and NPS4. The tubes are typically produced from steel conforming to specific mechanical and chemical properties, ensuring they meet the demands of fence construction.
The chemical composition of ASTM F1083 welded steel tubes is crucial for ensuring their performance. Below is a table summarizing the typical chemical composition:
| Element | Composition (%) |
|---|---|
| Carbon (C) | 0.18 max |
| Manganese (Mn) | 0.60 - 0.90 |
| Phosphorus (P) | 0.04 max |
| Sulfur (S) | 0.05 max |
| Silicon (Si) | 0.10 - 0.40 |
| Iron (Fe) | Balance |
The mechanical properties of the welded steel tubes are essential for their application in fence structures. The following table outlines the typical mechanical properties:
| Property | Value |
|---|---|
| Yield Strength (ksi) | 30 min |
| Tensile Strength (ksi) | 50 min |
| Elongation (%) | 20 min |
| Hardness (Rockwell) | B70 min |
The steel grade for ASTM F1083 welded steel tubes is typically designated as Grade A or Grade B, depending on the specific mechanical properties required for the application.
These welded steel tubes are primarily used in the construction of fences for various applications, including:
While ASTM F1083 is a widely accepted standard, there are alternative grades that can be considered based on specific project requirements. Some of these include:
A: manufacturer,also can do trading.
A: Generally speaking,it is 10-15 days if the goods are in stock,or it is 30-40 days if the goods are not in stock, it is according to quantity.
A: Yes, we could offer the sample for free charge but need pay the cost of freight.
A: Payment<=2000USD, 100% in advance. Payment>=2000USD, 30% T/T in advance ,balance before shippment.
