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.
