| Property | Value |
| Tensile Strength | 325 MPa min |
| Yield Strength | 180 MPa min |
| Elongation | 35% min |
| Hardness | HRB 80-90 |
Physical Properties
In addition to its chemical and mechanical properties, the seamless steel tube possesses certain physical characteristics. These properties include:
| Property | Value |
| Density | 7.85 g/cm³ |
| Melting Point | 1420-1460°C |
| Thermal Conductivity | 51.9 W/m·K |
| Electrical Conductivity | 1.45 MS/m |
| Modulus of Elasticity | 200 GPa |
Process Performance
The seamless steel tube is produced using a cold-drawn process, which involves pulling the tube through a die to achieve the desired dimensions. This manufacturing technique ensures the tube's excellent surface finish, dimensional accuracy, and enhanced mechanical properties. The cold-drawn process also enhances the tube's resistance to corrosion and provides better tolerance control.
Application
The ASTM A556 seamless steel tube is specifically designed for use in heat exchangers. Heat exchangers are widely used in various industries, including power generation, chemical processing, oil and gas, and HVAC systems. The seamless carbon steel tube's high strength and resistance to high temperatures make it ideal for transferring heat between two fluids while maintaining structural integrity.
