ASTM A334 Gr.6 Alloy Steel Seamless Tube For Boiler And Heat Exchanger
ASTM A334 Gr. 6 is a specification for seamless and welded carbon and alloy steel tubes designed for low-temperature service. These tubes are widely used in industries where excellent toughness and durability at sub-zero temperatures are critical. Below is a comprehensive overview of ASTM A334 Gr. 6 alloy steel seamless tubes:
1. Material and Composition
ASTM A334 Gr. 6 is primarily a carbon and alloy steel material. Its composition ensures ductility, toughness, and strength under extreme low-temperature conditions. The chemical composition for Grade 6 typically includes:
| Element | Percentage |
|---|---|
| Carbon (C) | Max 0.30% |
| Manganese (Mn) | 0.29–1.06% |
| Phosphorus (P) | Max 0.025% |
| Sulfur (S) | Max 0.025% |
| Silicon (Si) | 0.10–0.50% |
2. Key Mechanical Properties
| Property | Value |
|---|---|
| Tensile Strength | Min 415 MPa (60 ksi) |
| Yield Strength | Min 240 MPa (35 ksi) |
| Elongation (in 2 inches) | Min 30% |
| Impact Toughness (Charpy) | Specified for low-temperature performance |
3. Manufacturing Process
ASTM A334 Gr. 6 seamless tubes are manufactured using the following steps:
4. Low-Temperature Suitability
The Grade 6 alloy is designed for low-temperature applications, with guaranteed impact toughness at temperatures as low as -45°C (-50°F). This makes it ideal for environments such as:
