ASTM A671 is a specification for electric fusion welded steel pipe suitable for atmospheric and lower temperature service. This article provides an overview of ASTM A671 CB60, CB65, and CB70 steel pipes, including their material, specification, key features, chemical composition, mechanical properties, steel grades, applications, and possible alternative grades.
ASTM A671 CB60, CB65, and CB70 steel pipes are made from carbon-manganese steel plates, which are electric fusion welded. These pipes are designed for atmospheric and lower temperature applications, where high strength and toughness are required.
The specification for ASTM A671 CB60, CB65, and CB70 steel pipes includes the following requirements:
The key features of ASTM A671 CB60, CB65, and CB70 steel pipes are as follows:
| Element | CB60 Composition (%) | CB65 Composition (%) | CB70 Composition (%) |
|---|---|---|---|
| Carbon | 0.19 max | 0.24 max | 0.31 max |
| Manganese | 0.95 max | 1.15 max | 1.30 max |
| Phosphorus | 0.025 max | 0.025 max | 0.025 max |
| Sulfur | 0.025 max | 0.025 max | 0.025 max |
| Silicon | 0.13 max | 0.13 max | 0.13 max |
| Nickel | 0.40 max | 0.40 max | 0.40 max |
| Chromium | 0.15 max | 0.15 max | 0.15 max |
| Molybdenum | 0.25 max | 0.25 max | 0.25 max |
| Copper | 0.50 max | 0.50 max | 0.50 max |
| Property | CB60 Minimum Yield Strength (MPa) | CB65 Minimum Yield Strength (MPa) | CB70 Minimum Yield Strength (MPa) |
|---|---|---|---|
| Tensile Strength | 415 | 450 | 485 |
| Yield Strength | 240 | 265 | 290 |
| Elongation in 2 inches (%) | 22 | 20 | 18 |
| Impact Test | -50°C (-58°F) | -50°C (-58°F) | -50°C (-58°F) |
ASTM A671 CB60, CB65, and CB70 steel pipes are categorized based on their minimum yield strength. CB60 has a minimum yield strength of 415 MPa, CB65 has a minimum yield strength of 450 MPa, and CB70 has a minimum yield strength of 485 MPa.
ASTM A671 CB60, CB65, and CB70 steel pipes are widely used in various industries for applications that require reliable and durable piping systems at atmospheric and lower temperatures. Some common applications include:
While ASTM A671 CB60, CB65, and CB70 steel pipes are specifically designed for atmospheric and lower temperature service, there are alternative grades available for different temperature ranges and specific requirements. Some possible alternative grades include:
It is important to consult the project specifications and requirements to determine the most suitable alternative grade for specific applications.
