Steel Grade

The steel grades specified in DIN 28181 include:

  • P235GH: A non-alloy steel grade suitable for pressure vessels and heat exchangers.
  • 16Mo3: A chromium-molybdenum alloy steel known for its high-temperature strength.
  • P215NL: A low-alloy steel grade with good weldability and toughness.
  • X5CrNi18-10: Austenitic stainless steel with excellent corrosion resistance.
  • X5CrNiMo17-12-2: Austenitic stainless steel with added molybdenum for enhanced corrosion resistance.

Application

These welded steel tubes are primarily used in:

  • Heat Exchangers: For transferring heat between fluids.
  • Boilers: In power generation and industrial processes.
  • Pressure Vessels: For storing gases and liquids under pressure.
  • Chemical Processing: In environments where corrosion resistance is critical.

Possible Alternative Grades

Depending on specific application requirements, alternative grades may include:

  • P265GH: Similar to P235GH but with higher strength.
  • SAE 304: An alternative austenitic stainless steel with good corrosion resistance.
  • SAE 316: Offers better corrosion resistance than 304, especially in chloride environments.
  • P355GH: A higher strength alternative for pressure applications.
