Stainless steel industrial pipes play a crucial role in modern industry and architectural applications, with their excellent properties making them the material of choice in many fields. Below are the main characteristics and applications of different types of stainless steel industrial pipes:

  1. 304L Stainless Steel Industrial Pipe:
    • Low carbon 304 steel
    • Excellent resistance to intergranular corrosion
    • Maintains good corrosion resistance after welding without heat treatment
  2. 304 Stainless Steel Industrial Pipe:
    • Good corrosion resistance, heat resistance, and low-temperature strength
    • Excellent mechanical properties and thermal processing characteristics
    • Applications: Cutlery, cabinets, boilers, automotive parts, medical equipment, building materials, food industry
    • Operating temperature range: -196°C to 700°C
  3. 310 Stainless Steel Industrial Pipe:
    • Main feature is high-temperature resistance
    • Commonly used in boiler interiors and automobile exhaust pipes
  4. 303 Stainless Steel Industrial Pipe:
    • Addition of small amounts of sulfur and phosphorus for easier machining
    • Other properties similar to 304
  5. 302 Stainless Steel Industrial Pipe:
    • Widely used in automotive parts, aerospace, hardware tools, chemical industry, etc.
    • Austenitic steel, higher hardness than 304 (HRC≤28)
    • Good rust and corrosion resistance
  6. 301 Stainless Steel Industrial Pipe:
    • Good ductility, suitable for formed products
    • Good weldability, better wear resistance and fatigue strength than 304
  7. 202 and 201 Stainless Steel Industrial Pipes:
    • Chromium-nickel-manganese austenitic stainless steel
    • 202 performs better than 201
    • 201 has lower magnetic properties
  8. 410 Stainless Steel Industrial Pipe:
    • Martensitic high-strength chromium steel
    • Good wear resistance but poorer corrosion resistance
  9. 420 Stainless Steel Industrial Pipe:
    • “Cutlery grade” martensitic steel
    • Used for surgical instruments, can be polished to a very bright finish
  10. 430 Stainless Steel Industrial Pipe:
    • Ferritic stainless steel
    • Mainly used for decorative purposes, such as automotive trim
    • Good formability but poorer temperature resistance and corrosion resistance

Overall, stainless steel industrial pipes are widely used in modern industry due to their excellent corrosion resistance, strength, and processing properties. Different types of stainless steel industrial pipes are suitable for various application scenarios, and can be selected based on specific requirements. These characteristics make stainless steel industrial pipes indispensable materials in industries such as construction, chemical, food, and medical sectors.
