P235GH Steel Typical Applications
P235GH steel plate is mainly used in equipment working under moderate pressure and elevated temperature, including:
- Pressure vessels and pressure containers
- Industrial boilers and boiler drums
- Heat exchangers and condensers
- Storage tanks for oil, gas and chemical media
- Process piping and pipe components
- Petrochemical reactors and separators
This grade is especially suitable for oil & gas, petrochemical plants, power stations and industrial energy projects, where stable performance and safety are critical.
Why Choose P235GH Steel Plate?
Compared with ordinary carbon steel, P235GH offers several practical benefits:
- Reliable strength at elevated temperatures, suitable for long-term service
- Excellent weldability, reducing fabrication difficulty and welding costs
- Good forming and bending performance, ideal for vessel and boiler manufacturing
- Stable impact toughness, ensuring safety under pressure conditions
- Cost-effective solution for pressure equipment compared with higher alloy grades
For projects that do not require very high strength but demand safe, stable and economical materials, P235GH is often the preferred choice.
Delivery Condition & Supply Form
P235GH steel plates are normally supplied in the Normalized (N) condition, which ensures:
Uniform grain structure
Stable mechanical properties

Packing
What is P235gh equivalent to?
Equivalent Astm Material is A285 Grade C.
Is P235gh carbon steel?
P235GH is a normalized carbon alloy steel and is available ex-stock from our warehouse with mill certification and stamping.
What is the difference between P235gh and P265gh?
The major difference between both these grades is their mechanical properties. P235gh is designed with a minimum yield strength of 235mpa with a minimum tensile strength between 360 to 480mpa. P265gh grade possesses a minimum yield strength of 265mpa with a tensile strength between 410 to 530mpa min.
