GJB 1951 38Cra 15CrA 20CrA 10A 45A structural steel is a high-quality material designed for demanding applications, particularly in the aviation industry. This steel is known for its excellent mechanical properties, durability, and resistance to environmental stressors, making it ideal for manufacturing structural components and seamless pipes.
The chemical composition of GJB 1951 38Cra 15CrA 20CrA 10A 45A structural steel is critical to its performance. Below is a table presenting the typical chemical composition:
| Element | 38Cra (%) | 15CrA (%) | 20CrA (%) | 10A (%) | 45A (%) |
|---|---|---|---|---|---|
| Carbon (C) | 0.35-0.45 | 0.12-0.18 | 0.17-0.23 | 0.07-0.13 | 0.42-0.50 |
| Chromium (Cr) | 0.80-1.10 | 0.90-1.20 | 0.90-1.20 | - | - |
| Manganese (Mn) | 0.50-0.80 | 0.30-0.60 | 0.50-0.80 | 0.30-0.60 | 0.50-0.80 |
| Silicon (Si) | 0.17-0.37 | 0.17-0.37 | 0.17-0.37 | 0.17-0.37 | 0.17-0.37 |
| Phosphorus (P) | ≤0.035 | ≤0.035 | ≤0.035 | ≤0.035 | ≤0.035 |
| Sulfur (S) | ≤0.035 | ≤0.035 | ≤0.035 | ≤0.035 | ≤0.035 |
The mechanical properties of this structural steel are essential for its performance in aviation applications. The table below outlines the typical mechanical properties:
| Property | 38Cra | 15CrA | 20CrA | 10A | 45A |
|---|---|---|---|---|---|
| Tensile Strength (MPa) | 800-950 | 600-750 | 700-850 | 500-650 | 800-950 |
| Yield Strength (MPa) | 600-750 | 400-550 | 500-650 | 300-450 | 600-750 |
| Elongation (%) | ≥12 | ≥15 | ≥14 | ≥18 | ≥12 |
| Impact Energy (J) | ≥40 | ≥35 | ≥40 | ≥30 | ≥40 |
The steel grades covered under GJB 1951 include 38Cra, 15CrA, 20CrA, 10A, and 45A. Each grade is tailored to specific applications, offering a range of mechanical properties and chemical compositions to suit different needs.
These structural steel pipes and bars are primarily used in the aviation industry for:
While GJB 1951 38Cra 15CrA 20CrA 10A 45A offers excellent properties, alternative grades may be considered based on specific requirements:
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.
