EN10216 P235GH and P195GH are non-alloy carbon steel grades specified in the European standard for seamless tubes designed for high-temperature and pressure applications. These tubes are widely used in boilers, heat exchangers, and industrial systems requiring reliability under thermal stress.
| Property | P235GH | P195GH |
|---|---|---|
| Material Type | Non-alloy carbon steel (high-temperature grade) | Non-alloy carbon steel (general-purpose grade) |
| Chemical Composition | C (≤0.16%), Mn (0.50-1.20%), Si (≤0.35%), low S/P (≤0.025%) | C (≤0.13%), Mn (0.40-1.20%), Si (≤0.35%), low S/P (≤0.025%) |
| Mechanical Properties | - Yield strength (Rp0.2): ≥235 MPa - Tensile strength (Rm): 360-510 MPa - Elongation (A5): ≥24% |
- Yield strength (Rp0.2): ≥195 MPa - Tensile strength (Rm): 330-510 MPa - Elongation (A5): ≥25% |
| High-Temperature Performance | - Stable up to 450°C (842°F) - Excellent creep resistance for long-term thermal loads |
- Suitable for ≤350°C (662°F) - Good oxidation resistance at moderate temperatures |
| Weldability | - Easily weldable with low-hydrogen electrodes - Preheating (100-200°C) recommended for thick sections |
- Excellent weldability with standard techniques - Minimal preheating required |
Standards & Compliance |
EN10216-2 (seamless tubes for high-temperature service) | EN10216-1/2 (general pressure purposes) |
Robust Mechanical Integrity:
High yield and tensile strength ensure reliability in pressurized systems.
P235GH excels in high-temperature environments, while P195GH offers cost efficiency for moderate conditions.
Superior Weldability and Formability:
Both grades support seamless welding and cold-forming processes, reducing fabrication complexity.
Thermal Stability:
Oxidation resistance and creep strength make P235GH ideal for boilers and superheaters.
P195GH performs well in low-to-medium temperature applications (e.g., water pipelines).
Compliance with Global Standards:
Manufactured under strict EN10216 guidelines, including hydrostatic testing, ultrasonic inspection (UT), and dimensional checks.
P235GH:
Power plant boilers and steam pipelines.
High-temperature heat exchangers and pressure vessels.
Petrochemical processing equipment.
P195GH:
Low-pressure boilers and hydraulic systems.
Structural components in HVAC and water distribution.
Industrial fluid transport at moderate temperatures.
Testing: Hydrostatic/pneumatic tests, non-destructive testing (NDT), and chemical/mechanical certification.
Traceability: Full material traceability ensures compliance with EN10216 specifications.
