Physical properties

Appearance: Smooth surface, silvery white, no obvious flaws, with metallic luster.

Density: about 7.93g/cm³, heavier than ordinary steel, weight factor should be considered during handling and use. – **Melting point**: 1398℃-1454℃, with a high melting point, it can still maintain a certain structural stability under high temperature environment, suitable for some occasions requiring high temperature resistance.

Thermal conductivity: 16.3 W·m⁻¹·K⁻¹ at 100℃, 21.5 W·m⁻¹·K⁻¹ at 500℃, relatively low thermal conductivity, with good thermal insulation performance.

Linear expansion coefficient: 17.2×10⁻⁶ K⁻¹ at 0℃-100℃, 18.4×10⁻⁶ at 0℃-500℃ K⁻¹, will produce a certain amount of thermal expansion and contraction when the temperature changes, but the degree is relatively small.

Resistivity: 0.73×10⁻⁶Ω·m²/m at 20℃, with certain conductivity, but relatively large resistance.

Magnetism: It belongs to austenitic stainless steel, theoretically non-magnetic, but may produce slight magnetism after cold processing or welding.

Strength: tensile strength σb ≥ 515MPa-1035MPa, conditional yield strength σ0.2 ≥ 205MPa, high strength, can withstand large external forces and loads. – **Hardness**: Hardness ≤ 201HBW, ≤ 92HRB, ≤ 210HV, with good wear resistance and deformation resistance.

Chemical properties

Corrosion resistance: Chromium content is 18%-20%, nickel content is 8%-10.5%, can maintain good chemical stability in various media such as atmosphere, fresh water, general acid and alkaline solutions, and is not easy to rust and corrode. However, in an environment containing a large amount of chloride ions, such as seawater and salt spray environments, the corrosion resistance will decrease, and pitting and crevice corrosion may occur.

Antioxidation: At room temperature, a dense chromium oxide film can form on the surface of 304 stainless steel angle steel. This oxide film can prevent oxygen from further reacting with the internal metal, making it have good antioxidation properties. In a high temperature environment, its antioxidation properties will be weakened, but it can still maintain a certain stability.

High temperature stability: In a high temperature environment, 304 stainless steel angle steel can maintain good strength and toughness, and can be used normally within a certain temperature range (such as -196℃-800℃), but its performance will change with the increase or decrease of temperature.

Application:

304 stainless steel angle steel is widely used. In the construction industry, it is often used to build building frames and make curtain wall keels. Its corrosion resistance can resist wind and rain erosion and ensure long-term stability of the building. In terms of interior decoration, it is used to make stair handrails and railings, which are beautiful and durable. In the industrial field, it is a high-quality material for various equipment brackets and guardrails, which can withstand certain pressure and impact. In food processing environments, it can be used to make shelves and transmission tracks, which meet hygiene standards and ensure food safety. In furniture manufacturing, table and chair frames can be constructed to increase product strength and texture, and adapt to a variety of use scenarios.
