BS 6323-4 is a British Standard that specifies the requirements for cold finished seamless carbon steel tubes. This standard covers various grades of seamless steel tubes, including CFS3, CFS4, CFS5, CFS6, and CFS7. These tubes are widely used in various industries due to their excellent mechanical properties and high resistance to corrosion. This article will provide an overview of the material, specification, key features, chemical composition, mechanical properties, steel grades, applications, and possible alternative grades for BS 6323-4 CFS3 CFS4 CFS5 CFS6 CFS7 seamless steel tubes.
BS 6323-4 CFS3 CFS4 CFS5 CFS6 CFS7 seamless steel tubes are manufactured using high-quality carbon steel. These tubes are cold finished, which means they undergo a final cold drawing process to achieve the desired dimensions and surface finish. The tubes are available in various sizes and thicknesses, meeting the specific requirements of different applications.
The key features of BS 6323-4 CFS3 CFS4 CFS5 CFS6 CFS7 seamless steel tubes include:
| Element | CFS3 (%) | CFS4 (%) | CFS5 (%) | CFS6 (%) | CFS7 (%) |
|---|---|---|---|---|---|
| Carbon (C) | 0.17-0.24 | 0.25-0.32 | 0.28-0.34 | 0.33-0.39 | 0.38-0.44 |
| Silicon (Si) | 0.17-0.37 | 0.17-0.37 | 0.17-0.37 | 0.17-0.37 | 0.17-0.37 |
| Manganese (Mn) | 0.35-0.65 | 0.35-0.65 | 0.35-0.65 | 0.35-0.65 | 0.35-0.65 |
| Phosphorus (P) | 0.035 max | 0.035 max | 0.035 max | 0.035 max | 0.035 max |
| Sulfur (S) | 0.035 max | 0.035 max | 0.035 max | 0.035 max | 0.035 max |
| Property | CFS3 | CFS4 | CFS5 | CFS6 | CFS7 |
|---|---|---|---|---|---|
| Tensile Strength | 320-440 MPa | 370-490 MPa | 410-530 MPa | 450-570 MPa | 490-610 MPa |
| Yield Strength | 180 MPa min | 230 MPa min | 270 MPa min | 310 MPa min | 350 MPa min |
| Elongation | 30% min | 25% min | 23% min | 21% min | 19% min |
| Hardness (Rockwell B) | 65 max | 75 max | 80 max | 85 max | 90 max |
BS 6323-4 CFS3 CFS4 CFS5 CFS6 CFS7 seamless steel tubes are classified into different steel grades based on their chemical composition and mechanical properties. These grades provide a standardized way to specify the quality and characteristics of the tubes.
BS 6323-4 CFS3 CFS4 CFS5 CFS6 CFS7 seamless steel tubes find applications in various industries, including:
While BS 6323-4 CFS3 CFS4 CFS5 CFS6 CFS7 seamless steel tubes offer excellent performance, there are alternative grades available in the market that may suit specific requirements. Some possible alternative grades include ASTM A519, DIN 2391, and JIS G3445 seamless steel tubes. It is essential to consult the relevant standards and specifications to determine the most suitable alternative grade for a particular application.
