| 304 is a general-purpose stainless steel that is widely used in the manufacture of equipment and components that require good comprehensive performance (corrosion resistance and formability). 304 stainless steel is a grade of stainless steel produced in accordance with the American ASTM standard. 304 is equivalent to 0Cr19Ni9 (0Cr18Ni9) stainless steel in China. 304 contains 19% chromium and 9% nickel. 304 is the most widely used stainless steel, heat-resistant steel, practical steel and Huaye steel. It is used in food production equipment, general chemical equipment, nuclear energy, etc. A high-alloy steel that can resist corrosion in air or chemical corrosive media. To maintain the inherent corrosion resistance of stainless steel, the steel must contain more than 12% chromium. Chemical composition of 304 stainless steel: Specification C Si Mn P S Cr Ni (Nickel) Mo SUS304 ≤0.08 ≤1.00 ≤2.00 ≤0.05 ≤0.03 18.00-20.00 8.25-10.50. 304 stainless steel pipes, as stainless heat-resistant steel, are used in food equipment, general chemical equipment, and atomic energy industry equipment. The anti-rust performance of 304 stainless steel is stronger than that of 200 series stainless steel materials. It also has good heat resistance, capable of withstanding temperatures up to 1000 to 1200 degrees. 304 stainless steel features excellent corrosion resistance and good resistance to intergranular corrosion. 304 stainless steel material has strong corrosion resistance in nitric acid with a concentration of no more than 65% and a boiling temperature below. It also has good corrosion resistance to alkaline solutions and most organic and inorganic acids. Stainless steel is a kind of high-alloy steel that can resist corrosion in the air or chemical corrosive media. It has an attractive surface and good corrosion resistance. It can exert the inherent surface properties of stainless steel without surface treatment such as coloring and is used in many aspects. It is usually called stainless steel. The representative ones in terms of performance include 13-chromium steel, 18-8 chromium-nickel steel and other high alloy steels. The weight formula for stainless steel pipes :[(outer diameter - wall thickness)* wall thickness]*0.02491=kg/ meter (weight per meter). The theoretical weight calculation formula for 304 stainless steel pipes: (outer diameter - wall thickness) × wall thickness ×0.02491= weight per meter (kg) Mechanical properties Yield strength (N/mm ²) ≥205 Tensile strength ≥520 Elongation (%) ≥40 Hardness HB ≤187, HRB≤90, HV≤200 Density: 7.93 g·cm-3 Specific heat: c(20℃)0.502 J·(g·C) ⁻ ¹ Thermal conductivity λ/W(m·℃)-1 (at the following temperatures /℃) 20 100 500 12.1 16.3 21.4 Linear expansion coefficient α/(10-6/℃) (at the following temperatures /℃) 20 ~ 10020 ~ 200 20 ~ 300 20 ~ 400 16.0 16.8 17.5 18.1 Resistivity: 0.73 Ω·mm ² ·m ⁻ ¹ Melting point: 1398-1420℃ |
