Physical and chemical properties:Density: The density of 304 stainless steel is about 7.93g/cm ³.
Melting point: The melting point range is between 1398 ° C and 1454 ° C.
Thermal conductivity: 16.3 W · m ¬ K ¬ at 100 ° C and 21.5 W · m ¬ K ¬ at 500 ° C.
Linear expansion coefficient: When 0 ℃ -100 ℃, the linear expansion coefficient is 17.2 × 10~ K ^, and when 0 ℃ -500 ℃, it is 18.4 × 10~ K ^.
Resistivity: At 20 ° C, the resistivity is 0.73 × 10 Ω · m.
Longitudinal modulus of elasticity: The longitudinal modulus of elasticity at 20 ° C is 193 KN/mm ².
Hardness: Brinell hardness ≤ 187HB, Rockwell hardness ≤ 90HRB, Vickers hardness ≤ 200HV.
Tensile strength: ≥ 520MPa.
Conditional yield strength: ≥ 205MPa.
Elongation: ≥ 40%.
Section shrinkage rate: ≥ 60%.
Magnetic: 304 stainless steel is basically non-magnetic and only slightly magnetic when cold worked.
Corrosion resistance: 304 stainless steel contains about 18% -20% chromium and 8% -10.5% nickel. Chromium can form a dense passivation film on the surface of the steel, isolating the metal from the outside world, resulting in good corrosion resistance. It performs well in corrosive environments such as atmosphere, water, steam, and some acid and alkali solutions, and can resist the erosion of general oxidation, reduction, acidic and alkaline media.
Oxidation resistance: 304 stainless steel can maintain good oxidation resistance within a certain high temperature range, and its operating temperature limit is generally less than 650 ° C. Below this temperature, it can resist oxidation and maintain the stability of the material.
Chemical stability: 304 stainless steel can maintain a relatively stable chemical state under the action of many chemicals, and is not easy to chemically react with common chemicals. Therefore, it is widely used in food processing, medical equipment manufacturing, and other fields that require high chemical stability. It will not have harmful chemical reactions with food ingredients or medical disinfectants.
