EN 10025 Grade RSt37-2Cu3 untreated

EN 10025 Grade RSt37-2Cu3 untreated introduction

RSt37-2Cu3 is used for welded constructions stress dependent up to - 25 °C. It shows a better corrosion behaviour because of the Cu content.

Equivalent material: DIN 1.0167, DIN S235JRG2Cu, EN S235JRG2Cu, EN 1.0167
