Welding Procedure Qualification Record (WPQR) for Böhler K700 steel
Our company was approved to the WPQR for steel Böhler K700 in May 2016. Böhler K700 is the trade name for austenitic manganese steel DIN 1.3401 / EN X120Mn12.
The Steel is wear resisting hard manganese steel featuring high toughness and excellent weldability which acquires its working hardness (surface hardness up to 600 Vickers) by strain hardening, thus being particularly suited for applications involving wear by impact or pressure. The steel is not recommended to be machined, thus welding is the only method for connecting plates of different thicknesses. Our company has the WPQR for fillet welding and for partial butt welding
