Chemical Composition – P235GH
| Element | C | Si | Mn | P max | S max | Al |
|---|---|---|---|---|---|---|
| Requirement | ≤0.16 | ≤0.35 | 0.60-1.20 | 0.025 | 0.015 | ≥0.020 |
💡 Low phosphorus and sulfur ensures excellent toughness and weldability for pressure equipment service. Aluminum (≥0.020%) provides grain refinement for improved properties.
Mechanical Properties
| Property | Value | Significance |
|---|---|---|
| Tensile Strength | 360 – 500 MPa | Adequate for pressure equipment |
| Yield Strength | ≥235 MPa | Good strength for general pressure |
| Elongation | ≥25% | Excellent ductility for forming |
| Charpy Impact (TC2) | 27J min at 0°C | Guaranteed low temperature toughness |
TC1 vs TC2 – Quality Levels
| Feature | TC1 | TC2 |
|---|---|---|
| Charpy Impact Test | Not required | Required (27J at 0°C) |
| NDT Requirements | Standard | Stricter acceptance |
| Typical Application | General pressure equipment | Critical applications, low temp start-up |
| Cost | $ | $$ |
💡 Choose TC2 when impact toughness is required – typically specified for low temperature start-up conditions or critical pressure equipment.
Manufacturing Process – Cold Drawing
Cold Drawing Process for Pressure Tubes:
-
Hot rolled tubes are pickled to remove scale
-
Cold drawing precisely reduces the diameter – increases strength
-
Annealing (normalizing) – ensures fine grain structure, restores ductility
-
Straightening – ensures straightness for installation
-
Precision cutting – to exact customer length
-
100% NDT and hydrostatic testing – guarantees integrity
-
Charpy impact testing (TC2) – verifies low temperature toughness
Elevated Temperature Yield Strength (Rp0.2 MPa min)
| Temp (°C) | 50 | 100 | 150 | 200 | 250 | 300 | 350 | 400 |
|---|---|---|---|---|---|---|---|---|
| P235GH | 190 | 180 | 170 | 155 | 145 | 135 | 130 | 120 |
💡 P235GH maintains good strength up to 400°C – above this temperature, use 16Mo3 or 13CrMo4-5 alloy grades.
Key Applications
| Industry | Application | Recommended Quality |
|---|---|---|
| Power Generation | Boiler tubes, low pressure steam | TC1, TC2 |
| Pressure Vessels | Drums, accumulators, headers | TC1, TC2 |
| Industrial Boilers | Steam generators, economizers | TC1 |
| Heat Exchangers | Shell and tube assemblies | TC1, TC2 |
| Petrochemical | High temperature process piping | TC2 |
💡 TC2 is recommended for critical applications requiring impact toughness at low temperature start-up conditions.
DIN 17175 Cross-Reference
| EN 10216-2 | DIN 17175 (Withdrawn) |
|---|---|
| P235GH | St35.8 |
| P265GH | St45.8 |
| 16Mo3 | 15Mo3 |
| 13CrMo4-5 | 13CrMo44 |
💡 P235GH is the direct replacement for St35.8 – for legacy projects, we supply both standards.
