EN 10277-2 S235JRG2C: Premium Cold-Drawn Steel for Folding & Cold Forming

S235JRG2C is used for folding, cold forming and cold drawing grade. The steel is applicable for welding constructions of temperatures up to -20°C depending on load. Max. product thickness accounts 20 mm for folding grades and 8 mm for cold forming grades. As a bright steel product it is used in the form of bars, bright, straight, in various conditions (see DIN EN 10277 : 1999-10).
