430 stainless steel is a ferritic stainless steel with a smaller thermal expansion coefficient than austenite. Its tensile strength, yield strength and elongation are higher than 430F and 430LX. It is often used in architectural decoration, such as railings, handrails, stairs, doors and windows, etc.; household appliances, such as tableware, cooking utensils, etc.

The mechanical and physical properties of 430 stainless steel pipe are as follows:

Mechanical behavior:

1. Tensile strength: 450-600 MPa.
2. Yield strength: 220-275 MPa.
3. Elongation: 20-25%.

Physical properties:

1. Density: 7.8 g/cm3.
2. Thermal expansion coefficient: 10.2×10^-6/℃ (in the range of 20-100℃).
3. Thermal conductivity: 16.2 W/(m·K).Resistivity: 0.73 Ω·mm2/m (at 20℃).
4. Magnetism: The processed state is ferromagnetic, and the annealed state is non-ferromagnetic.
5. Modulus of elasticity: 180 GPa (at 20°C).
6. Specific heat capacity: 502 J/(kg·K) (at 20℃).
7. Heat capacity: 460 J/(kg·℃) (at 20℃).c
