EN10216-2 P235GH TC1 Alloy Steel Heat Exchanger Tube For Power Plants

EN 10216-2: This European standard specifies requirements for seamless tubes made from carbon and alloy steel for pressure equipment and piping systems, particularly for high-temperature service where pressure resistance and good mechanical properties are essential.

P235GH: A non-alloy steel grade offering good weldability, moderate strength, and excellent high-temperature performance. The "P" indicates pressure applications, while "235" refers to the minimum yield strength (235 MPa) at room temperature.

GH: Indicates the steel grade is designed for high-temperature applications (typically up to 400°C+), making it suitable for heat exchangers, boilers, and other high-pressure equipment.

• Tensile Strength (R_m): 360-510 MPa
• Yield Strength (R_eH): ≥ 235 MPa
• Elongation: 22% (in 5.65 √S)
• Hardness: Typically ≤ 180 HB

• Yield Strength: Minimum 235 MPa at room temperature, suitable for medium-pressure applications
• Tensile Strength: 360-510 MPa range ensures capability to handle mechanical stresses
• Temperature Resistance: Designed for elevated temperature environments with resistance to creep and high-temperature oxidation
