list of EN10253-2 P265GH pipe fittings

 

P265GH is a low alloy high temperature structural steel, in accordance with the European standard EN10253-2. It is a kind of European standard boiler vessel plate.

In P265GH steel grade, G stands for others, H stands for high temperature, P stands for steel for pressure bearing components, and 265 stands for standard yield strength. It is equivalent to 25MnG in China. 25MnG is GB 5310-2008 high pressure boiler material, the performance and material of both are roughly the same. P265GH has good plasticity, toughness, cold bending and weldability, and is often used in nuclear power plant, boiler manufacturing, pressure vessel and pipeline transportation of hot liquid.

Heat treatment: heat treatment temperature 1100 ~ 850 ℃, normalizing temperature 520 ~ 580 ℃, annealing temperature 890 ~ 950 ℃.

Delivery status: Normalized +Tempered.
