P235GH is a European standard pressure vessel steel with the designation EN 10028-2. Here is an overview of its typical material composition:
1. Carbon (C): The carbon content of P235GH material is typically around 0.16% - 0.20%.
2. Manganese (Mn): The manganese content ranges from 0.60% - 1.20%. Manganese improves the strength and hardenability of the steel.
3. Phosphorus (P): The maximum phosphorus content is restricted to 0.025%. Lower phosphorus content helps improve the weldability and ductility of the steel.
4. Sulfur (S): The maximum sulfur content is limited to 0.015%. Low sulfur content improves the steel's machinability and reduces the risk of hot cracking during welding.
5. Silicon (Si): The silicon content typically ranges from 0.10% - 0.35%. Silicon contributes to the steel's strength and enhances its resistance to oxidation and scaling at elevated temperatures.
6. Other elements: P235GH may also contain small amounts of other elements such as copper (Cu), nickel (Ni), and aluminum (Al), among others, depending on the specific manufacturing processes and requirements.
It's essential to note that precise material composition may vary slightly depending on the manufacturer and specific product specifications. Consulting the manufacturer or referring to the relevant standards is recommended for accurate and up-to-date information regarding P235GH material composition.
