Frequently asked questions about S235JR
Can S235JR be used for pressure applications?
S235JR is a structural steel – for pressurised piping, creep-resistant boiler steels such as P235GH are used.
What does JR mean in S235JR?
J stands for the impact energy (27 J) and R for the test temperature at room temperature (+20 °C).
Request S235JR?
Grade, standard, size, pressure rating and quantity are enough – on request with an EN 10204 3.1 / 3.2 mill certificate. Your quote usually the same day.
All data are typical values per the relevant EN standards for first orientation – without warranty. The applicable standard and the mill certificate of the delivery are decisive.
